Persian domes or Iranian domes have an ancient origin and a history extending to the modern era. The use of domes in ancient Mesopotamia was carried forward through a succession of empires in the Greater Iran region.
142-404: An ancient tradition of royal audience tents representing the heavens was translated into monumental stone and brick domes due to the invention of the squinch , a reliable method of supporting the circular base of a heavy dome upon the walls of a square chamber. Domes were built as part of royal palaces, castles, caravansaries, and temples, among other structures. With the introduction of Islam in
284-507: A Babylonian rabbi called Samuel . This friendship was advantageous for the Jewish community and gave them a respite from the oppressive laws enacted against them. Later kings reversed Shapur's policy of religious tolerance. When Shapur's son Bahram I acceded to the throne, he was pressured by the Zoroastrian high-priest Kartir Bahram I to kill Mani and persecute his followers. Bahram II
426-525: A central dome with smaller domes on either side and elaborate muqarnas . An exaggerated style of onion dome on a short drum, as can be seen at the Shah Cheragh (1852–1853), first appeared in the Qajar period. Domes have remained important in modern mausoleums, such as the tombs of Ḥāfeẓ , Saʿdī , Reza Shah , and Ruhollah Khomeini in the twentieth century. Domed cisterns and icehouses remain common sights in
568-450: A central oculus in each dome, as at the Palace of Ardashir and as shown in the bas relief found at Kuyunjik, lighting was provided by a number of hollow terracotta cylinders set into the domes at regular intervals. Multiple written accounts from Arabic, Byzantine, and Western medieval sources describe a palace domed structure over the throne of Chosroes decorated in blue and gold. The dome
710-573: A dome chamber almost completely covered with decorative tilework is that of the Jame Mosque of Yazd (1364), as well as several of the mausoleums of Shah-i-Zinda in Samarkand . The development of taller drums also continued into the Timurid period. The mass killings by Mongol and Timurid troops impeded developments in geometry between 1000 and 1400. The mathematician al-Kashi (1390-1450) further developed
852-541: A domed throne room. Chahar-taqi , or "four vaults", were smaller Zoroastrian fire temple structures with four supports arranged in a square, connected by four arches, and covered by central ovoid domes. The Niasar Zoroastrian temple in Kashan and the chahar-taqi in Darreh Shahr are examples. They are numerous throughout the province of Pars , possibly starting from the early Sasanian empire, and are known to be part of
994-584: A funerary association with the domed form. The area of north-eastern Iran was, along with Egypt, one of two areas notable for early developments in Islamic domed mausoleums, which appear in the tenth century. The earliest known Islamic domes in Persia, such as the Great Mosque of Qom (878) and the tomb of Muhammed b. Musa (976), seem to have continued the rounded Sasanian form. Domed mausoleums contributed greatly to
1136-735: A further development at the shrine of Shaykh Abd al-Samad in Natanz, Iran. The architecture of Syria and the Jazira includes the widest variety of forms in the medieval Islamic world, being influenced by the surviving architecture of Late Antiquity , contemporary Christian buildings, and Islamic architecture from the east. There are some muqarnas domes of the Iraqi type, but most domes are slightly pointed hemispheres on either muqarnas pendentives or double zones of squinches and made of masonry, rather than brick and plaster. The domes cover single bay structures or are just
1278-559: A general amnesty, which brought Armenia back into the Sassanid Empire. Around 570, "Ma 'd-Karib", half-brother of the King of Yemen, requested Khosrow I's intervention. Khosrow I sent a fleet and a small army under a commander called Vahriz to the area near present Aden , and they marched against the capital San'a'l, which was occupied. Saif, son of Mard-Karib, who had accompanied the expedition, became King sometime between 575 and 577. Thus,
1420-620: A hollow, open half-cone (like a funnel) laid horizontally; or a small half-dome niche. They are designed to spread the load of a dome to the intersecting walls on which they are built. By bridging corners, they also visually transition an angular space to a round or near-circular zone. Squinches originated in the Sassanid Empire of Ancient Persia, remaining in use across Central and West Asia into modern times. From its pre-Islamic origin, it developed into an influential structure for Islamic architecture. Georgia and Armenia also inherited
1562-495: A hunting trip in 309. Following Hormizd II's death, northern Arabs started to ravage and plunder the western cities of the empire, even attacking the province of Fars, the birthplace of the Sassanid kings. Meanwhile, Persian nobles killed Hormizd II's eldest son, blinded the second, and imprisoned the third (who later escaped into Roman territory). The throne was reserved for Shapur II , the unborn child of one of Hormizd II's wives who

The Sasanian Empire's cultural influence extended far beyond the physical territory that it controlled, impacting regions as distant as Western Europe , Eastern Africa , and China and India . It also helped shape European and Asian medieval art. With
1846-581: A major Byzantine offensive in Armenia was defeated at Anglon . Also in 541, Khosrow I entered Lazica at the invitation of its king, captured the main Byzantine stronghold at Petra , and established another protectorate over the country, commencing the Lazic War . A five-year truce agreed to in 545 was interrupted in 547 when Lazica again switched sides and eventually expelled its Persian garrison with Byzantine help;
1988-681: A member of the Parthian House of Karen , one of the Seven Great Houses of Iran , quickly raised a new force and stopped the Hephthalites from achieving further success. Peroz's brother, Balash , was elected as shah by the Iranian magnates, most notably Sukhra and the Mihranid general Shapur Mihran . Balash (484–488) was a mild and generous monarch, and showed care towards his subjects, including

He exploited his success by advancing into Anatolia (260), but withdrew in disarray after defeats at the hands of the Romans and their Palmyrene ally Odaenathus , suffering the capture of his harem and the loss of all the Roman territories he had occupied. Shapur had intensive development plans. He ordered the construction of
2272-544: A network of small domes and windows to provide light to the interior. Palace gardens included open-plan domed pavilions. Safavid examples were expanded or imitated, as in the golden domes at Qom , Ray , and Mashhad . The movement to modern architecture meant less innovation in dome construction. Domes were built over madrasas, such as the 1848 Imam madrasa, or Sultani school, of Kashan , but they have relatively simple appearances and do not use tiled mosaics. The covered markets or bazaars ( tīmcās ) at Qom and Kashan feature
2414-616: A number of battles he crushed them and drove them out beyond the Oxus river in 450. During his eastern campaign, Yazdegerd II grew suspicious of the Christians in the army and expelled them all from the governing body and army. He then persecuted the Christians in his land, and, to a much lesser extent, the Jews . In order to reestablish Zoroastrianism in Armenia, he crushed an uprising of Armenian Christians at
2556-653: A part of larger constructions. Syrian mausoleums consist of a square stone chamber with a single entrance and a mihrab and a brick lobed dome with two rows of squinches. The dome at the Silvan Mosque, 13.5 meters wide and built from 1152 to 1157, has an unusual design similar to the dome added to the Friday Mosque of Isfahan in 1086-1087: once surrounded by roofless aisles on three sides, it may have been meant to be an independent structure. The congregational mosque at Kızıltepe , with its well integrated dome of about 10 meters,
2698-412: A pilgrimage site. This did not occur and it became his own mausoleum instead. The dome measures 50 meters high and almost 25 meters in diameter and has the best surviving tile and stucco work from this period. The thin, double-shelled dome was reinforced by arches between the layers. The dome has been proposed as an influence on the design of that of Florence Cathedral , built a century later. The mausoleum
2840-410: A rational system of taxation based upon a survey of landed possessions , which his father had begun, and he tried in every way to increase the welfare and the revenues of his empire. Previous great feudal lords fielded their own military equipment, followers, and retainers. Khosrow I developed a new force of dehqans , or "knights", paid and equipped by the central government and the bureaucracy, tying
2982-457: A relatively peaceful era with the Romans, and he even took the young Theodosius II (408–450) under his guardianship. Yazdegerd also married a Jewish princess, who bore him a son called Narsi. Yazdegerd I's successor was his son Bahram V (421–438), one of the most well-known Sasanian kings and the hero of many myths. These myths persisted even after the destruction of the Sasanian Empire by

In 1088 Tāj-al-Molk , a rival of Nizam al-Mulk, built another dome at the opposite end of the same mosque with interlacing ribs forming five-pointed stars and pentagons. This is considered the landmark Seljuk dome, and may have inspired subsequent patterning and the domes of the Il-Khanate period. The five-fold geometry of this design, a spherical dodecahedron , has led to speculation that mathematician Omar Khayyam

The tent had four archways and was surrounded by a lower attached portico or gallery on all four sides. A miniature painted at Samarkand shows that bulbous cupolas were used to cover small wooden pavilions in Persia by the beginning of the 15th century. They gradually gained in popularity. The large, bulbous, fluted domes on tall drums that are characteristic of 15th century Timurid architecture were

Shapur therefore marched east toward Transoxiana to meet the eastern nomads, leaving his local commanders to mount nuisance raids on the Romans. He crushed the Central Asian tribes, and annexed the area as a new province. In the east around 325, Shapur II regained the upper hand against the Kushano-Sasanian Kingdom and took control of large territories in areas now known as Afghanistan and Pakistan . Cultural expansion followed this victory, and Sasanian art penetrated Transoxiana , reaching as far as China. Shapur, along with
3550-448: A third conical shell over the existing two domed shells. The domes of the Safavid dynasty (1501–1732) are characterized by a distinctive bulbous profile and are considered to be the last generation of Persian domes. They are generally thinner than earlier domes and are decorated with a variety of colored glazed tiles and complex vegetal patterns. A popular feature of Safavid architecture was
3692-467: A wooden dome. The room "contained a portrait of Mithradates II and, along with other structures at the site, hosted some sort of cult activities connected to the memory of the kings of kings." The Sun Temple at Hatra appears to indicate a transition from columned halls with trabeated roofing to vaulted and domed construction in the first century AD, at least in Mesopotamia.

In 230, Ardashir raided deep into Roman territory, and a Roman counter-offensive two years later ended inconclusively. Ardashīr began leading campaigns into Greater Khurasan as early as 233, extending his power to Khwarazm in

The Mausoleum of Fakhreddin Razi [ tk ] in Konye-Urgench , Turkmenistan , was built with a discontinuous double-shell dome with an outer conical shell. After the disruptive effects of several Mongol invasions , Persian architecture again flourished in the Ilkhanate and Timurid periods. Characteristic of these domes are the use of high drums and several types of discontinuous double-shells, and
4402-508: Is the only remaining important building to survive from Öljaitü's capital city. Tower tombs of this period, such as the tomb of Abdas-Samad Esfahani in Natanz , sometimes have muqarnas domes, although they are usually plaster shells that hide the underlying structures. The tall proportions of the Jameh Mosque of Varamin resulted primarily from the increased height of the zone of transition, with

The palace of Ālī Qāpū includes small domed rooms decorated with artificial vegetation. The removal of thousands of Armenian Christians to the Isfahan suburb city of New Julfa by Shah Abbas resulted in the "unusual sight of Ṣafawid-style domes topped by a cross" in that city.

His book, Key of Arithmetic , included five methods of drawing an arch profile and he created methods to calculate the surface areas and volumes of dome shells. They were frequently used in dome design. In the Timurid period, taller domes were built, often as double-shell domes, and melon domes were built in Samarqand , Herat , Balkh , and Kirmān . Muqarnas features held in place by "slats and scaffolding anchored by mortar" were used in

After the rise of Islam, it remained a feature of Islamic architecture , especially in Iran , and was often covered by corbelled stalactite-like structures known as muqarnas . It was used in the Middle East and in eastern Romanesque architecture , although pendentives are more common in Byzantine architecture. The Hagia Sophia features both squinches and pendentives, in combination. It spread to

Previous transitions to a dome from a square chamber existed but were makeshift in quality and only attempted on a small scale, not being reliable enough for large constructions. The squinch enabled domes to be widely used and they moved to

Mausoleums were rarely built as free-standing structures after the 14th century, being instead often attached to madrasas in pairs. Domes of these madrasas, such as those of the madrasa of Gawhar Shad (1417–1433) and
6390-491: The 7th century , mosque and mausoleum architecture also adopted and developed these forms. Structural innovations included pointed domes, drums, conical roofs, double and triple shells, and the use of muqarnas and bulbous forms. Decorative brick patterning, interlaced ribs, painted plaster, and colorful tiled mosaics were used to decorate the exterior as well as the interior surfaces. Persian architecture likely inherited an architectural tradition of dome-building dating back to

Khosrow's generals systematically subdued the heavily fortified frontier cities of Byzantine Mesopotamia and Armenia, laying the foundations for unprecedented expansion. The Persians overran Syria and captured Antioch in 611. In 613, outside Antioch, the Persian generals Shahrbaraz and Shahin decisively defeated a major counter-attack led in person by

Both were physically and diplomatically powerful, opportunistic, practiced religious tolerance and provided freedom for the rise of religious minorities. Yazdegerd stopped the persecution against the Christians and punished nobles and priests who persecuted them. His reign marked

The Sassanid dream of restoring the Achaemenid boundaries was almost complete, while the Byzantine Empire was on the verge of collapse. This remarkable peak of expansion was paralleled by a blossoming of Persian art , music , and architecture . While successful at its first stage (from 602 to 622),

Capitalizing on this success, the Persians then ravaged Syria, causing Justin II to agree to make annual payments in exchange for a five-year truce on the Mesopotamian front, although the war continued elsewhere. In 576 Khosrow I led his last campaign, an offensive into Anatolia which sacked Sebasteia and Melitene , but ended in disaster: defeated outside Melitene,

The octagonal mausoleum of Khwaja Rabi (1617–1622) uses the oldest version of the Safavid onion dome type. The tomb of Amin-edin Jabrail [ fa ] , begun in 1380, was completed around 1700. Fath-Ali Shah Qajar built a series of mosques named "Masjid-i Shāh" at Qazvin (1808), Zanjan , Semnan (1827), Tehran (1840), and Borujerd . They include
9940-399: The Tigris, and agreed not to interfere in the affairs of Armenia and Georgia. In the aftermath of this defeat, Narseh gave up the throne and died a year later, leaving the Sassanid throne to his son, Hormizd II . Unrest spread throughout the land, and while the new king suppressed revolts in Sakastan and Kushan, he was unable to control the nobles and was subsequently killed by Bedouins on
10082-691: The Tigris, had to hand over all the provinces the Persians had ceded to Rome in 298, as well as Nisibis and Singara, to secure safe passage for his army out of Persia. From around 370, however, towards the end of the reign of Shapur II , the Sasanians lost the control of Bactria to invaders from the north: first the Kidarites , then the Hephthalites and finally the Alchon Huns , who would follow up with an invasion of India . These invaders initially issued coins based on Sasanian designs. Various coins minted in Bactria and based on Sasanian designs are extant, often with busts imitating Sassanian kings Shapur II (r. 309 to 379) and Shapur III (r. 383 to 388), adding
10224-459: The Timurid era. The dome of the Amir Chakhmaq mosque (1437) has a semi-circular inner shell and an advanced system of stiffeners and wooden struts supporting a shallow pointed outer shell. Notably, the dome has a circular drum with two tiers. Another double shell dome from the early Seljuq period at the shrine complex of Bayazid Bastami was changed in the Timurid period in 1300 by the addition of
10366-592: The Timurid period the curved surface was divided by a pattern of intersecting arches called an "arch net", or rasmi sazi , which had its culmination in the Safavid period. Persian domes from different historical eras can be distinguished by their transition tiers: the squinches, spandrels, or brackets that transition from the supporting structures to the circular base of a dome. Drums, after the Ilkanate era, tend to be very similar and have an average height of 30 to 35 meters from
10508-458: The addition of a sixteen-sided section above the main zone of muqarnas squinches. The tomb of Hamd-allah Mustawfi was built around 1340. The 7.5 meter wide double dome of Soltan Bakht Agha Mausoleum (1351–1352) is the earliest known example in which the two shells of the dome have significantly different profiles, which spread rapidly throughout the region. The inner and outer shells had radial stiffeners and struts between them. An early example of
10650-444: The alliance, Khosrow also married Maurice's daughter Miriam. Under the command of Khosrow and the Byzantine generals Narses and John Mystacon , the new combined Byzantine-Persian army raised a rebellion against Bahram, defeating him at the Battle of Blarathon in 591. When Khosrow was subsequently restored to power he kept his promise, handing over control of western Armenia and Caucasian Iberia . The new peace arrangement allowed
10792-421: The army and bureaucracy more closely to the central government than to local lords. Emperor Justinian I (527–565) paid Khosrow I 440,000 pieces of gold as a part of the "eternal peace" treaty of 532. In 540, Khosrow broke the treaty and invaded Syria, sacking Antioch and extorting large sums of money from a number of other cities. Further successes followed: in 541 Lazica defected to the Persian side, and in 542
10934-460: The attention of Artabanus IV, the Parthian king, who initially ordered the governor of Khuzestan to wage war against Ardashir in 224, but Ardashir was victorious in the ensuing battles. In a second attempt to destroy Ardashir, Artabanus himself met Ardashir in battle at Hormozgan, where the former met his death. Following the death of the Parthian ruler, Ardashir went on to invade the western provinces of
11076-436: The campaign of Khosrau II had actually exhausted the Persian army and treasuries. In an effort to rebuild the national treasuries, Khosrau overtaxed the population. Thus, while his empire was on the verge of total defeat, Heraclius (610–641) drew on all his diminished and devastated empire's remaining resources, reorganised his armies, and mounted a remarkable, risky counter-offensive. Between 622 and 627, he campaigned against
11218-598: The ceiling, which corresponds to Buyid burial customs described in the 14th century. The Seljuq Turks built tower tombs, called "Turkish Triangles", as well as cube mausoleums covered with a variety of dome forms. Seljuk domes included conical, semi-circular, and pointed shapes in one or two shells. Shallow semi-circular domes are mainly found from the Seljuk era. The double-shell domes were either discontinuous or continuous. The continuous double-shell domes separated from one another at an angle of 22.5 degrees from their base, such as
11360-619: The coinage of Bukhara (in modern Uzbekistan ). Bahram deposed the vassal king of the Iranian-held area of Armenia and made it a province of the empire. Bahram V's son Yazdegerd II (438–457) was in some ways a moderate ruler, but, in contrast to Yazdegerd I, he practised a harsh policy towards minority religions, particularly Christianity . However, at the Battle of Avarayr in 451, the Armenian subjects led by Vardan Mamikonian reaffirmed Armenia's right to profess Christianity freely. This
11502-472: The countryside. The Melik Gazi tomb in Turkey was built in 1200. Squinch In architecture , a squinch is a structural element used to support the base of a circular or octagonal dome that surmounts a square-plan chamber. Squinches are placed to diagonally span each upper corner where the walls meet. Constructed from masonry, they have several forms, including: a graduated series of stepped arches;
11644-473: The culmination of the Central Asian and Iranian tradition of tall domes with glazed tile coverings in blue and other colors. The Mausoleum of Khoja Ahmed Yasawi , situated in southern Kazakhstan was never finished, but has the largest existing brick dome in Central Asia , measuring 18.2 m in diameter. The dome exterior is covered with hexagonal green glazed tiles with gold patterns. In Afghanistan, Timurid ribbed domes with glazed tiles began to be built in
11786-627: The details of the fall of the Parthian Empire and subsequent rise of the Sassanian Empire in mystery. The Sassanian Empire was established in Estakhr by Ardashir I . Ardashir's father, Papak , was originally the ruler of a region called Khir. However, by 200, Papak had managed to overthrow Gochihr and appoint himself the new ruler of the Bazrangids . Papak's mother, Rodhagh, was the daughter of
11928-538: The development and spread of the dome in Persia early in the Islamic period. By the 10th century, domed tombs had been built for Abbasid caliphs and Shiite martyrs. Pilgrimage to these sites may have helped to spread the form. The earliest surviving example in Islamic architecture, the Qubbat-al Sulaibiya [ ar ] , was an octagonal structure with a central dome on a drum built around 892 in Samarra on
12070-429: The development of triple-shells and internal stiffeners occurred at this time. Beginning in the Ilkanate, Persian domes achieved their final configuration of structural supports, zone of transition, drum, and shells, and subsequent evolution was restricted to variations in form and shell geometry. The construction of tomb towers decreased. The tomb of Ala al-Din was built in 1289. The Shaykh abd al-samad shrine complex
12212-661: The dome of the Friday mosque in Ardestan , whereas the discontinuous domes remained completely separate, such as those of the tower tombs of Kharrqan. This pair of brick tower tombs from the 11th century in Kharraqan, Iran, are the earliest known masonry double shell domes. The domes may have been modeled on earlier wooden double shell domes, such as that of the Dome of the Rock . It is also possible, because
12354-523: The dome. Cylindrical or polygonal plan tower tombs with conical roofs over domes also exist beginning in the 11th century. The earliest example is the Gonbad-e Qabus tower tomb , 57 meters high and spanning 9.7 meters, which was built in 1007. Although no burial has been found at the site, the Ziyarid ruler was purported by a 16th century Arab historian to have been in a glass coffin suspended by chains from
12496-450: The domed enclosure in front of the mosque's mihrab , which would become popular in Persian congregational mosques , although domed rooms may have also been used earlier in small neighborhood mosques. The domed enclosure of the Jameh Mosque of Isfahan , built in 1086-7 by Nizam al-Mulk , was the largest masonry dome in the Islamic world at that time, had eight ribs, and introduced a new form of corner squinch with two quarter domes supporting
12638-573: The earliest Mesopotamian domes. In Central Asia, mudbrick domes have been documented as far back as the late third millennium BC. Buildings with domes made of un-fired bricks have been found at fourth century BC sites at Balandy 2 and Koj Krylgan kala in Khorezm . Due to the scarcity of wood in many areas of the Iranian plateau , domes were an important part of vernacular architecture throughout Persian history. Persian dome chambers in mosques were derived from
12780-421: The empire passed on to his half-brother Ardashir II (379–383; son of Hormizd II) and his son Shapur III (383–388), neither of whom demonstrated their predecessor's skill in ruling. Bahram IV (388–399) also failed to achieve anything important for the empire. During this time Armenia was divided by a treaty between the Roman and Sasanian empires. The Sasanians reestablished their rule over Greater Armenia, while
12922-437: The empire. Nonetheless, Ardashir I further expanded his new empire to the east and northwest, conquering the provinces of Sakastan , Gorgan , Khorasan , Marw (in modern Turkmenistan ), Balkh and Chorasmia . He also added Bahrain and Mosul to the Sassanid possessions. Later Sassanid inscriptions also claim the submission of the kings of Kushan , Turan and Makuran to Ardashir, although based on numismatic evidence it
13064-521: The forefront of Persian architecture as a result. The ruins of the Palace of Ardashir and Ghal'eh Dokhtar in Fars Province , Iran, built by Ardashir I (224–240) of the Sasanian Empire, have the earliest known examples of squinches. The three domes of the Palace of Ardashir are 45 feet in diameter and vertically elliptical, each with a central opening or oculus to admit light. They were built with local stone and mortar and covered with plaster on
13206-595: The form from the Sassanids, where squinches were widely employed in buildings of all kinds. They are heavily featured in surviving or ruined medieval Christian churches of the region. An alternative approach to the structural problem of translating square space to round superstructure is the pendentive , much used in late Roman Empire and Byzantine architecture. Domes built in the Roman-influenced world utilised separately-evolved construction methods. The dome chamber in
13348-567: The former's disadvantage: the rugged Armenian terrain was favourable to Roman infantry, but not to Sassanid cavalry. Local aid gave Galerius the advantage of surprise over the Persian forces, and, in two successive battles, Galerius secured victories over Narseh. During the second encounter, Roman forces seized Narseh's camp, his treasury, his harem, and his wife. Galerius advanced into Media and Adiabene , winning successive victories, most prominently near Erzurum , and securing Nisibis ( Nusaybin , Turkey) before 1 October 298. He then advanced down
13490-546: The frontiers to act as guardians against invaders. He was tolerant of all religions, though he decreed that Zoroastrianism should be the official state religion , and was not unduly disturbed when one of his sons became a Christian. After Khosrow I, Hormizd IV (579–590) took the throne. The war with the Byzantines continued to rage intensely but inconclusively until the general Bahram Chobin , dismissed and humiliated by Hormizd, rose in revolt in 589. The following year, Hormizd
13632-550: The ground. They are where windows are located. Inner shells are commonly semi-circular, semi-elliptical, pointed, or saucer shaped. The outer shell of a Persian dome reduces in thickness every 25 or 30 degrees from the base. Outer shells can be semi-circular, semi-elliptical, pointed, conical, or bulbous, and this outer shape is used to categorize them. Pointed domes can be sub-categorized as having shallow, medium, and sharp profiles, and bulbous domes as either shallow or sharp. Double domes use internal stiffeners with wooden struts between
13774-459: The head of a large army granted to him by the Hephthalite king, returned to the empire's capital. Jamasp stepped down from his position and returned the throne to his brother. No further mention of Jamasp is made after the restoration of Kavad I, but it is widely believed that he was treated favourably at the court of his brother. The second golden era began after the second reign of Kavad I. With
13916-498: The inclusion of symmetrical pairs of key elements, including dome chambers. Extensive and colorful tilework was used in this period, including floral and arabesque patterns on dome exteriors, enabled by the use of less expensive large square underglaze -painted tiles that were not dependent on firing special glazes at the optimum temperature in order to achieve the coloration. Small scale domes were included in palace architecture, utility structures, and caravanserais . The dome of
14058-551: The interior to hide the squinches, arches, and vaults actually supporting the domes. The external zone of transition to the dome was reduced or removed, such as stepped features, polygonal drums, and galleries. Jahangir Mausoleum in Uzbekistan was built in 1400. At the Timurid capital of Samarkand, nobles and rulers in the 14th and 15th centuries began building tombs with double-shelled domes containing cylindrical masonry drums between
14200-572: The interior. At the center of the palace of Shahpur, at Bishapur, there is a vertically- elliptical dome that rests directly on the ground and is dated to 260. The large brick dome of the Sarvestan Palace , also in Fars but later in date, shows more elaborate decoration and four windows between the corner squinches. Also called "the Temple of Anahita", the building may have been a Fire temple . Instead of using
14342-498: The kingdom. Peroz tried again to drive out the Hephthalites, but on the way to Balkh his army was trapped by the Huns in the desert. Peroz was defeated and killed by a Hephthalite army near Balkh. His army was completely destroyed, and his body was never found. Four of his sons and brothers had also died. The main Sasanian cities of the eastern region of Khorasan − Nishapur , Herat and Marw were now under Hephthalite rule. Sukhra ,
14484-428: The madrasa at Ḵargerd (1436–1443), had dramatically innovative interiors. They used intersecting arches to support an inner dome narrower than the floor below, a change that may have originated with the 14th century use of small lantern domes over transverse vaulting. The madrasa of Gawhar Shad is also the first triple-shell dome. The middle dome may have been added as reinforcement. Triple-shelled domes are rare outside of
14626-462: The majority of the domes in the Islamic periods. Although the Sasanians did not create monumental tombs, the domed chahar-taqi may have served as memorials. A Soghdian painting fragment from the early eighth century found at Panjakent appears to depict a funerary dome (possibly a tent) and this, along with a few ossuaries of an architectural nature, indicates a possible tradition in central Asia of
14768-526: The most common form was a single shell of brick, with the reverse of the interior pattern visible on the exterior. The Damascus mausoleum of Nur al-Din (1172) and the shrine of Zumurrud Khatun in Baghdad are examples. The dome of Nur al-Din was originally hemispherical and similar to those of the mosques of the Artuqids , but it has been replaced with a style of dome similar to those used in local shrines. A third type
14910-629: The neighbouring Roman Empire . It was founded by Ardashir I , a ruler who rose to power as Parthia weakened amidst internal strife and the Roman–Persian Wars . After defeating Artabanus IV of Parthia during the Battle of Hormozdgan in 224, Ardashir's dynasty replaced that of the Arsacids and promptly set out to restore the legacy of the Achaemenid Empire by expanding the newly acquired Sasanian dominions. At its greatest territorial extent,
15052-402: The nomad King Grumbates , started his second campaign against the Romans in 359 and soon succeeded in retaking Singara and Amida. In response the Roman emperor Julian struck deep into Persian territory and defeated Shapur's forces at Ctesiphon . He failed to take the capital, however, and was killed while trying to retreat to Roman territory. His successor Jovian , trapped on the east bank of
15194-477: The north and Sistan in the south while capturing lands from Gorgan to Abarshahr, Marw, and as far east as Balkh . Ardashir I's son Shapur I continued the expansion of the empire, conquering Bactria and the western portion of the Kushan Empire, while leading several campaigns against Rome. Invading Roman Mesopotamia , Shapur I captured Carrhae and Nisibis , but in 243 the Roman general Timesitheus defeated
15336-502: The now defunct Parthian Empire. At that time the Arsacid dynasty was divided between supporters of Artabanus IV and Vologases VI , which probably allowed Ardashir to consolidate his authority in the south with little or no interference from the Parthians. Ardashir was aided by the geography of the province of Fars, which was separated from the rest of Iran. Crowned in 224 at Ctesiphon as
15478-538: The palatial architecture of Ardashir I. Such temples, square domed buildings with entrances at the axes, inspired the forms of early mosques after the Islamic conquest of the empire in the 7th century. These domes are the most numerous surviving type from the Sasanian period, with some having been converted into mosques. The later isolated dome chambers called the "kiosk mosque" type may have developed from this. Pre-Islamic domes in Persia are commonly semi-elliptical, with pointed domes and those with conical outer shells being
15620-417: The petty landholding nobility who were the backbone of later Sassanid provincial administration and the tax collection system. Khosrow I built infrastructure, embellishing his capital and founding new towns with the construction of new buildings. He rebuilt the canals and restocked the farms destroyed in the wars. He built strong fortifications at the passes and placed subject tribes in carefully chosen towns on
15762-445: The protests of his other brothers, who were put to death, Ardashir declared himself ruler of Pars. Once Ardashir was appointed shah (king), he moved his capital further to the south of Pars and founded Ardashir-Khwarrah (formerly Gur , modern day Firuzabad ). The city, well protected by high mountains and easily defensible due to the narrow passes that approached it, became the center of Ardashir's efforts to gain more power. It
15904-438: The provincial governor of Pars . Papak and his eldest son Shapur managed to expand their power over all of Pars. Subsequent events are unclear due to the elusive nature of the sources. It is certain that following the death of Papak, Ardashir, the governor of Darabgerd , became involved in a power struggle with his elder brother Shapur. Sources reveal that Shapur was killed when the roof of a building collapsed on him. By 208, over
16046-556: The rich should divide their wives and their wealth with the poor. By adopting the doctrine of the Mazdakites, his intention evidently was to break the influence of the magnates and the growing aristocracy. These reforms led to his being deposed and imprisoned in the Castle of Oblivion in Khuzestan , and his younger brother Jamasp (Zamaspes) became king in 496. Kavad, however, quickly escaped and
16188-572: The second longest-lived Persian imperial dynasty after the directly preceding Arsacid dynasty of Parthia . It fell to the Rashidun Caliphate during the early Muslim conquests , which marked the beginning of a monumental societal shift by initiating the Islamization of Iran . Upon succeeding the Parthians, the Sasanian dynasty re-established the Persian nation as a major power in late antiquity , and also continued to compete extensively with
16330-510: The shells of discontinuous double domes to provide structural stability as late at the 14th century. The large dome of Bibi-Khanym Mosque in Samarkand was damaged by an earthquake during Timur's lifetime. It was built between 1398 and 1405. An account by ambassador Ruy González de Clavijo describes a huge square Timurid pavilion tent with a dome at the top that resembled a castle from a distance due to its size. It measured one hundred paces on
16472-487: The shells, with the exception of those with conical outer shells. Although they had palaces of brick and stone, the kings of Achaemenid Persia held audiences and festivals in domical tents derived from the nomadic traditions of central Asia. They were likely similar to the later tents of the Mongol Khans . Called "Heavens", these tents emphasized the cosmic significance of the divine ruler. They were adopted by Alexander
16614-497: The shells. In the Gur-e Amir , built by Timur around 1404, a timber framework on the inner dome supports the outer, bulbous dome. Radial tie-bars at the base of the bulbous dome provide additional structural support. Timber reinforcement rings and rings of stone linked by iron cramps were also used to compensate for the structural problems introduced by using such drums. Radial sections of brick walls with wooden struts were used between
16756-403: The sole ruler of Persia, Ardashir took the title shahanshah , or "King of Kings" (the inscriptions mention Adhur-Anahid as his Banbishnan banbishn , "Queen of Queens", but her relationship with Ardashir has not been fully established), bringing the 400-year-old Parthian Empire to an end, and beginning four centuries of Sassanid rule. In the next few years, local rebellions occurred throughout
16898-572: The square room with the zone of transition and uses plain squinches like those of the earlier Seljuq period. On the exterior, multiple levels of glazed arabesque are blended with an unglazed brick background. The domes of the Shah Mosque (later renamed the Imam Mosque) and the Mādar-e Šāh madrasa (1706-1714) have a similar exterior pattern against a background of light blue glazed tile. The bulbous dome of
17040-485: The support of the Hephthalites , Kavad launched a campaign against the Romans. In 502, he took Theodosiopolis in Armenia, but lost it soon afterwards. In 503 he took Amida on the Tigris. In 504, an invasion of Armenia by the western Huns from the Caucasus led to an armistice, the return of Amida to Roman control and a peace treaty in 506. In 521/522 Kavad lost control of Lazica , whose rulers switched their allegiance to
17182-499: The temple was preceded by a barrel vaulted iwan , a combination that would be used by the subsequent Persian Sasanian Empire . A bulbous Parthian dome can be seen in the relief sculpture of the Arch of Septimius Severus in Rome, its shape apparently due to the use of a light tent-like framework. An account of a Parthian domed palace hall from around 100 AD in the city of Babylon can be found in
17324-652: The term is first attested in the trilingual Great Inscription of Shapur I , where the king says "I am the lord of the Empire of the Iranians". More commonly, as the ruling dynasty was named after Sasan , the empire is known as the Sasanian Empire in historical and academic sources. This term is also recorded in English as the Sassanian Empire , the Sasanid Empire , and the Sassanid Empire . Conflicting accounts shroud
17466-518: The two empires to focus on military matters elsewhere: Khosrow focused on the Sassanid Empire's eastern frontier while Maurice restored Byzantine control of the Balkans . Circa 600, the Hephthalites had been raiding the Sassanid Empire as far as Spahan in central Iran. The Hephthalites issued numerous coins imitating the coinage of Khosrow II. In c. 606/607 , Khosrow recalled Smbat IV Bagratuni from Persian Armenia and sent him to Iran to repel
17608-405: The upper portions of both of the outer shells are missing, that some portion of the outer domes may have been wooden. These brick mausoleum domes were built without the use of centering, a technique developed in Persia. The dome of a tomb at Sangbast [ fa ] has been dated to the 11th or 12th century and used brick arranged in a herringbone pattern . The Seljuq Empire introduced
17750-582: The war resumed but remained confined to Lazica, which was retained by the Byzantines when peace was concluded in 562. In 565, Justinian I died and was succeeded by Justin II (565–578), who resolved to stop subsidies to Arab chieftains to restrain them from raiding Byzantine territory in Syria. A year earlier, the Sassanid governor of Armenia, Chihor-Vishnasp of the Suren family, built a fire temple at Dvin near modern Yerevan , and he put to death an influential member of
17892-487: The war, defeated the Romans at Barbalissos (253), and then probably took and plundered Antioch . Roman counter-attacks under the emperor Valerian ended in disaster when the Roman army was defeated and besieged at Edessa and Valerian was captured by Shapur, remaining his prisoner for the rest of his life. Shapur celebrated his victory by carving the impressive rock reliefs in Naqsh-e Rostam and Bishapur , as well as
18034-470: Was a mausoleum with a square base roofed with two shells. Domed mausoleums in the Greater Khorasan region used a two story cubic structure covered by domes in two dissimilar shells, with a lack of structural knowledge resulting in damage to the outer pointed dome shells. An anonymous mausoleum and the mausoleum of Sultan Sanjar are examples, before conservation efforts. The largest Seljuq domed chamber
18176-540: Was also amenable to the wishes of the Zoroastrian priesthood. During his reign, the Sassanid capital Ctesiphon was sacked by the Romans under Emperor Carus , and most of Armenia, after half a century of Persian rule, was ceded to Diocletian . Succeeding Bahram III (who ruled briefly in 293), Narseh embarked on another war with the Romans. After an early success against the Emperor Galerius near Callinicum on
18318-677: Was built between 1000 and 1325. The two major domes of the IlKhanate period are the no-longer-existing mausoleum of Ghazan in Tabriz and the Mausoleum of Öljaitü in Soltaniyeh , the latter having been built to rival the former. Öljaitü was the first sovereign of Persia to declare himself of the Shia sect of Islam and built the mausoleum, with the largest Persian dome, to house the bodies of Ali and Hussein as
18460-492: Was covered with depictions of the sun, moon, stars, planets, the zodiac , astrapai, and kings, including Chosroes himself. According to Ado and others, the dome could produce rain, and could be rotated with a sound like thunder by means of ropes pulled by horses in a basement. The castle of Qasr-e Shirin had a domed chamber at the end of a long barrel-vaulted iwan. The late-Sasanian Tāq-i Kasrā in Ctesiphon may also have led to
18602-419: Was crowned in utero : the crown was placed upon his mother's stomach. During his youth the empire was controlled by his mother and the nobles. Upon coming of age, Shapur II assumed power and quickly proved to be an active and effective ruler. He first led his small but disciplined army south against the Arabs, whom he defeated, securing the southern areas of the empire. He then began his first campaign against
18744-443: Was defeated at the Battle of Dara . In the same year, a second Persian army under Mihr-Mihroe was defeated at Satala by Roman forces under Sittas and Dorotheus, but in 531 a Persian army accompanied by a Lakhmid contingent under Al-Mundhir III defeated Belisarius at the Battle of Callinicum , and in 532 an "eternal peace" was concluded. Kavad succeeded in restoring order in the interior and fought with general success against
18886-473: Was designed according to the geometric principles of mathematicians al-Khorezmi , al-Fargani , and Ibn-Sino . It dates to no later than 943 and is the first to have squinches create a regular octagon as a base for the dome, which then became the standard practice. The Arab-Ata Mausoleum , also in Transoxiana, may be dated to 977–78 and uses muqarnas between the squinches for a more unified transition to
19028-452: Was given refuge by the Hephthalite king. Jamasp (496–498) was installed on the Sasanian throne upon the deposition of Kavad I by members of the nobility. He was a good and kind king; he reduced taxes in order to improve the condition of the peasants and the poor. He was also an adherent of the mainstream Zoroastrian religion, diversions from which had cost Kavad I his throne and freedom. Jamasp's reign soon ended, however, when Kavad I, at
19170-564: Was included in a brick inscription band just below the dome, making it the earliest dated dome in central Iran . The ambulatory may have been for circumambulation , suggesting that the structure was a shrine to a descendant of the Prophet , or Imamzadeh . In the 10th century, domed mausoleums of the domed square type became popular in the Transoxiana region. The Ismail Samanid mausoleum in Bukhara
19312-422: Was involved in the design. The Jameh Mosque of Zavareh (1135-1136) is the earliest existing example of the standard Iranian mosque type in which four iwans are arranged around a courtyard, with a dome behind the qibla iwan. The layout is found in a group of mosques in the region centered around Isfahan. The use of tile and of plain or painted plaster to decorate dome interiors, rather than brick, increased under
19454-556: Was killed by his brother Peroz in 459. At the beginning of the 5th century, the Hephthalites (White Huns), along with other nomadic groups, attacked Iran. At first Bahram V and Yazdegerd II inflicted decisive defeats against them and drove them back eastward. The Huns returned at the end of the 5th century and defeated Peroz I (457–484) in 483. Following this victory, the Huns invaded and plundered parts of eastern Iran continually for two years. They exacted heavy tribute for some years thereafter. These attacks brought instability and chaos to
