149-661: Howth ( / ˈ h oʊ θ / HOHTH ; Irish : Binn Éadair , meaning 'Éadar's peak'; Old Norse : Hǫfuð ) is an affluent peninsular village and outer suburb of Dublin , Ireland . The district as a whole occupies the greater part of the peninsula of Howth Head , which forms the northern boundary of Dublin Bay , and includes the island of Ireland's Eye , which holds multiple natural protection designations. Howth has been settled since prehistoric times, and features in Irish mythology. A fishing village and small trading port from at least

Ptolemy reviewed standard (and ancient, disused ) musical tuning practice of his day, which he then compared to his own subdivisions of the tetrachord and the octave , which he derived experimentally using a monochord / harmonic canon. The volume ends with a more speculative exposition of the relationships between harmony, the soul ( psyche ), and the planets ( harmony of
447-540: A unique dialect of Irish developed before falling out of use in the early 20th century. With a writing system , Ogham , dating back to at least the 4th century AD, which was gradually replaced by Latin script since the 5th century AD, Irish has one of the oldest vernacular literatures in Western Europe . On the island, the language has three major dialects: Connacht , Munster and Ulster Irish . All three have distinctions in their speech and orthography . There
596-601: A Roman citizen, but was ethnically either a Greek or at least a Hellenized Egyptian. Astronomy was the subject to which Ptolemy devoted the most time and effort; about half of all the works that survived deal with astronomical matters, and even others such as the Geography and the Tetrabiblos have significant references to astronomy. Ptolemy's Mathēmatikē Syntaxis ( Greek : Μαθηματικὴ Σύνταξις , lit. ' Mathematical Systematic Treatise ' ), better known as
745-697: A bargaining chip during government formation in Northern Ireland, prompting protests from organisations and groups such as An Dream Dearg . Irish became an official language of the EU on 1 January 2007, meaning that MEPs with Irish fluency can now speak the language in the European Parliament and at committees, although in the case of the latter they have to give prior notice to a simultaneous interpreter in order to ensure that what they say can be interpreted into other languages. While an official language of

The Strategy was produced on 21 December 2010 and will stay in action until 2030; it aims to target language vitality and revitalization of the Irish language. The 30-page document published by the Government of Ireland details the objectives it plans to work towards in an attempt to preserve and promote both the Irish language and the Gaeltacht. It
1043-470: A coherent mathematical description, which persists to the present as just intonation – the standard for comparison of consonance in the many other, less-than exact but more facile compromise tuning systems. During the Renaissance , Ptolemy's ideas inspired Kepler in his own musings on the harmony of the world ( Harmonice Mundi , Appendix to Book V). The Optica ( Koine Greek : Ὀπτικά ), known as
1192-472: A cultural and social force. Irish speakers often insisted on using the language in law courts (even when they knew English), and Irish was also common in commercial transactions. The language was heavily implicated in the "devotional revolution" which marked the standardisation of Catholic religious practice and was also widely used in a political context. Down to the time of the Great Famine and even afterwards,

Exemptions are made from this requirement for students who were born or completed primary education outside of Ireland, and students diagnosed with dyslexia . NUI Galway is required to appoint people who are competent in the Irish language, as long as they are also competent in all other aspects of
1490-460: A fully recognised EU language for the first time in the state's history. Before Irish became an official language it was afforded the status of treaty language and only the highest-level documents of the EU were made available in Irish. The Irish language was carried abroad in the modern period by a vast diaspora , chiefly to Great Britain and North America, but also to Australia , New Zealand and Argentina . The first large movements began in
1639-402: A handful of places. Ptolemy's real innovation, however, occurs in the second part of the book, where he provides a catalogue of 8,000 localities he collected from Marinus and others, the biggest such database from antiquity. About 6 300 of these places and geographic features have assigned coordinates so that they can be placed in a grid that spanned the globe. Latitude was measured from
SECTION 10
#17328489329261788-492: A long exposition on the relationship between reason and sense perception in corroborating theoretical assumptions. After criticizing the approaches of his predecessors, Ptolemy argues for basing musical intervals on mathematical ratios (as opposed to the ideas advocated by followers of Aristoxenus ), backed up by empirical observation (in contrast to the excessively theoretical approach of the Pythagoreans ). Ptolemy introduces
1937-587: A method for specifying the location of the Sun in three pairs of locally oriented coordinate arcs as a function of the declination of the Sun, the terrestrial latitude, and the hour. The key to the approach is to represent the solid configuration in a plane diagram that Ptolemy calls the analemma . In another work, the Phaseis ( Risings of the Fixed Stars ), Ptolemy gave a parapegma , a star calendar or almanac , based on
2086-461: A much later pseudepigraphical composition. The identity and date of the actual author of the work, referred to now as Pseudo-Ptolemy , remains the subject of conjecture. Ptolemy wrote a work entitled Harmonikon ( Greek : Ἁρμονικόν ), known as the Harmonics , on music theory and the mathematics behind musical scales in three books. Harmonics begins with a definition of harmonic theory, with

Official documents of the Irish government must be published in both Irish and English or Irish alone (in accordance with the Official Languages Act 2003, enforced by An Coimisinéir Teanga , the Irish language ombudsman). The National University of Ireland requires all students wishing to embark on
2682-604: A promontory in the Censure area of Howth was formerly on the Record of Protected Structures but removed as there were no structural elements remaining above ground to warrant retention. Alternative protection remains under the National Monuments Acts 1930–2004, as a Record Monument RMP Ref No. DU019-007. Howth remains an active centre of the fishing industry, one of Ireland's "tier 2" fishing ports, with some processing performed in
2831-611: A religious context. An Irish translation of the Old Testament by Leinsterman Muircheartach Ó Cíonga , commissioned by Bishop Bedell , was published after 1685 along with a translation of the New Testament. Otherwise, Anglicisation was seen as synonymous with 'civilising' the native Irish. Currently, modern day Irish speakers in the church are pushing for language revival. It has been estimated that there were around 800,000 monoglot Irish speakers in 1800, which dropped to 320,000 by
2980-538: A result of linguistic imperialism . Today, Irish is still commonly spoken as a first language in Ireland's Gaeltacht regions, in which 2% of Ireland's population lived in 2022. The total number of people (aged 3 and over) in Ireland who declared they could speak Irish in April 2022 was 1,873,997, representing 40% of respondents, but of these, 472,887 said they never spoke it and a further 551,993 said they only spoke it within
3129-543: A temple at Canopus , around 146–147 AD, known as the Canobic Inscription . Although the inscription has not survived, someone in the sixth century transcribed it, and manuscript copies preserved it through the Middle Ages. It begins: "To the saviour god, Claudius Ptolemy (dedicates) the first principles and models of astronomy", following by a catalogue of numbers that define a system of celestial mechanics governing

#17328489329263278-478: A thousand years or more". It was first translated from Arabic into Latin by Plato of Tivoli (Tiburtinus) in 1138, while he was in Spain. Much of the content of the Tetrabiblos was collected from earlier sources; Ptolemy's achievement was to order his material in a systematic way, showing how the subject could, in his view, be rationalized. It is, indeed, presented as the second part of the study of astronomy of which
3427-617: A train". On 26 July 1914, 900 rifles were landed at Howth by Erskine Childers for the Irish Volunteers . Many were used against the British in the Easter Rising and in the subsequent Anglo-Irish War . Among the members of the Howth branches of the Irish Volunteers and Cumann na mBan who participated in this event were the well-known writers Padraic Colum and Mary Colum . Members of both

Birds seen regularly include razorbill, guillemot, fulmar, kittiwake, cormorant, stonechat, linnet, whitethroat, yellowhammer, skylark, wheatear, swallow, house martin, peregrine, buzzard and kestrel. Howth is also a destination for cyclists, joggers and hill-walkers alike, particularly on weekends. One attraction is the six-kilometre long Cliff Path Loop. The loop walk takes about two hours to complete,
3725-553: A view supported by the Stoics. Although mainly known for his contributions to astronomy and other scientific subjects, Ptolemy also engaged in epistemological and psychological discussions across his corpus. He wrote a short essay entitled On the Criterion and Hegemonikon ( Greek : Περὶ Κριτηρίου καὶ Ἡγεμονικοῡ ), which may have been one of his earliest works. Ptolemy deals specifically with how humans obtain scientific knowledge (i.e.,

The territory of Howth was confirmed to Almaric de St. Laurence by King John.... Tristam built his first castle overlooking the harbour and the St. Lawrence link remained until 2019 (see Earl of Howth ). The original title of Baron of Howth was granted to Almeric St. Lawrence by Henry II of England in 1181, for one Knight's fee . Howth

Howth is located on the peninsula of Howth Head , which begins around 11 kilometres (6.8 mi) east-north-east of Dublin 's GPO, on the north side of Dublin Bay . The village itself is located just over 14 kilometres (8.7 mi) by road from Dublin city centre (the ninth of a series of eighteenth-century milestones from the Dublin General Post Office (GPO)
4619-558: Is also a waypoint for aircraft approaching Dublin Airport . The Irish name for Howth is Binn Éadair, meaning Éadar's Peak or Hill. In Old Irish, the name is recorded as Etar, which was first plundered by the Vikings around 819. One of the possible origins of the Irish name is from Étar, wife of one of the five Fir Bolg chieftains who is reported to have died at Howth. The name Howth is thought to be of Norse origin, perhaps being derived from

There are Gaeltacht regions in the following counties: Gweedore ( Gaoth Dobhair ), County Donegal, is the largest Gaeltacht parish in Ireland. Irish language summer colleges in the Gaeltacht are attended by tens of thousands of teenagers annually. Students live with Gaeltacht families, attend classes, participate in sports, go to céilithe and are obliged to speak Irish. All aspects of Irish culture and tradition are encouraged. The Act
6854-462: The Almagest , is the only surviving comprehensive ancient treatise on astronomy. Although Babylonian astronomers had developed arithmetical techniques for calculating and predicting astronomical phenomena, these were not based on any underlying model of the heavens; early Greek astronomers, on the other hand, provided qualitative geometrical models to "save the appearances" of celestial phenomena without

Thus explanations of a sort are provided for the astrological effects of the planets , based upon their combined effects of heating, cooling, moistening, and drying. Ptolemy dismisses other astrological practices, such as considering the numerological significance of names, that he believed to be without sound basis, and leaves out popular topics, such as electional astrology (interpreting astrological charts to determine courses of action) and medical astrology , for similar reasons. The great respect in which later astrologers held
7450-410: The Geography is likely to be of different dates, in addition to containing many scribal errors. However, although the regional and world maps in surviving manuscripts date from c. 1300 AD (after the text was rediscovered by Maximus Planudes ), there are some scholars who think that such maps go back to Ptolemy himself. Ptolemy wrote an astrological treatise, in four parts, known by
7599-645: The Middle Ages . However, it is likely that only a few truly mastered the mathematics necessary to understand his works, as evidenced particularly by the many abridged and watered-down introductions to Ptolemy's astronomy that were popular among the Arabs and Byzantines. His work on epicycles has come to symbolize a very complex theoretical model built in order to explain a false assumption. Ptolemy's date of birth and birthplace are both unknown. The 14th-century astronomer Theodore Meliteniotes wrote that Ptolemy's birthplace

8046-784: The Optics, is a work that survives only in a somewhat poor Latin version, which, in turn, was translated from a lost Arabic version by Eugenius of Palermo ( c. 1154 ). In it, Ptolemy writes about properties of sight (not light), including reflection , refraction , and colour . The work is a significant part of the early history of optics and influenced the more famous and superior 11th-century Book of Optics by Ibn al-Haytham . Ptolemy offered explanations for many phenomena concerning illumination and colour, size, shape, movement, and binocular vision. He also divided illusions into those caused by physical or optical factors and those caused by judgmental factors. He offered an obscure explanation of

The Irish Times , referring to his analysis published in the Irish language newspaper Foinse , quoted him as follows: "It is an absolute indictment of successive Irish Governments that at the foundation of the Irish State there were 250,000 fluent Irish speakers living in Irish-speaking or semi Irish-speaking areas, but
11026-497: The Macedonian family's rule. The name Claudius is a Roman name, belonging to the gens Claudia ; the peculiar multipart form of the whole name Claudius Ptolemaeus is a Roman custom, characteristic of Roman citizens. This indicates that Ptolemy would have been a Roman citizen . Gerald Toomer, the translator of Ptolemy's Almagest into English, suggests that citizenship was probably granted to one of Ptolemy's ancestors by either
11175-597: The Republic of Ireland ), new appointees to the Civil Service of the Republic of Ireland , including postal workers , tax collectors , agricultural inspectors, Garda Síochána (police), etc., were required to have some proficiency in Irish. By law, a Garda who was addressed in Irish had to respond in Irish as well. In 1974, in part through the actions of protest organisations like the Language Freedom Movement ,
11324-499: The Summit, one running at sea level near the coast, towards Sutton Cross. Howth is at the end of a regional road ( R105 ) from Dublin. One branch of the DART suburban rail system has its physical terminus by the harbour, the other northern terminus being Malahide 's station, which is actually on a through line for mainline rail towards Belfast. Under the bus route network for Dublin overseen by
11473-455: The Sun or Moon illusion (the enlarged apparent size on the horizon) based on the difficulty of looking upwards. The work is divided into three major sections. The first section (Book II) deals with direct vision from first principles and ends with a discussion of binocular vision. The second section (Books III-IV) treats reflection in plane, convex, concave, and compound mirrors. The last section (Book V) deals with refraction and includes
11622-422: The ability to make any predictions. The earliest person who attempted to merge these two approaches was Hipparchus , who produced geometric models that not only reflected the arrangement of the planets and stars but could be used to calculate celestial motions. Ptolemy, following Hipparchus, derived each of his geometrical models for the Sun, Moon, and the planets from selected astronomical observations done in
11771-520: The appearances and disappearances of stars over the course of the solar year. The Planisphaerium ( Greek : Ἅπλωσις ἐπιφανείας σφαίρας , lit. ' Flattening of the sphere ' ) contains 16 propositions dealing with the projection of the celestial circles onto a plane. The text is lost in Greek (except for a fragment) and survives in Arabic and Latin only. Ptolemy also erected an inscription in
11920-682: The beginning of the following academic year. For a number of years there has been vigorous debate in political, academic and other circles about the failure of most students in English-medium schools to achieve competence in Irish, even after fourteen years of teaching as one of the three main subjects. The concomitant decline in the number of traditional native speakers has also been a cause of great concern. In 2007, filmmaker Manchán Magan found few Irish speakers in Dublin , and faced incredulity when trying to get by speaking only Irish in Dublin. He
12069-403: The book on astrology and attributed it to Ptolemy". Historical confusion on this point can be inferred from Abu Ma'shar's subsequent remark: "It is sometimes said that the very learned man who wrote the book of astrology also wrote the book of the Almagest . The correct answer is not known." Not much positive evidence is known on the subject of Ptolemy's ancestry, apart from what can be drawn from
12218-508: The centre and east is protected as part of a Special Area of Conservation of 2.3 square kilometres (570 acres), as well as by a Special Amenity Area Order. The peninsula has a number of small, fast-running streams, three of which run through the village, with more, including the Bloody Stream, in the adjacent Howth Demesne. The streams passing through the village are, from east to west, Coulcour Brook (falling to Balscadden Bay), Gray's Brook or
12367-597: The consent of the Local Government Board for Ireland and despite the opposition of North Dublin rural district council. In 1942, it was transferred to Dublin county borough , with Dublin Corporation superseding the urban district council. In 1985, it was removed from the city and reassigned to the county. In 1994, it was in the area that became Fingal , the successor north of the River Liffey to County Dublin. At
12516-516: The control of Irish and localised Norse forces until the invasion of Ireland by the Anglo-Normans in 1169. Without the support of either the Irish or Scandinavian powers, Howth was isolated and fell to the Normans in 1177. One of the victorious Normans, Armoricus (or Almeric) Tristram, was granted much of the land between the village and Sutton. According to the historian Samuel Lewis: In 1177, Sir Amorey Tristram and Sir John de Courcy landed here at
12665-506: The data needed to compute the positions of the Sun, Moon and planets, the rising and setting of the stars, and eclipses of the Sun and Moon, making it a useful tool for astronomers and astrologers. The tables themselves are known through Theon of Alexandria 's version. Although Ptolemy's Handy Tables do not survive as such in Arabic or in Latin, they represent the prototype of most Arabic and Latin astronomical tables or zījes . Additionally,
12814-525: The designated area by restricting development there, while recognising the need "to encourage tourism-related developments in the remainder of Howth". The SAAO area runs from the vicinity of Bottle Quay northeast to Muck Rock, east to the reservoir at Balkill, east and south around the Loughoreen Hills and Black Linn, then to the Summit, turning north along the line of the Coulcour Brook, then taking in
12963-734: The details of his name, although modern scholars have concluded that Abu Ma'shar's account is erroneous. It is no longer doubted that the astronomer who wrote the Almagest also wrote the Tetrabiblos as its astrological counterpart. In later Arabic sources, he was often known as "the Upper Egyptian ", suggesting he may have had origins in southern Egypt . Arabic astronomers , geographers , and physicists referred to his name in Arabic as Baṭlumyus ( Arabic : بَطْلُمْيوس ). Ptolemy wrote in Koine Greek , and can be shown to have used Babylonian astronomical data . He might have been
13112-402: The earliest surviving table of refraction from air to water, for which the values (with the exception of the 60° angle of incidence) show signs of being obtained from an arithmetic progression. However, according to Mark Smith, Ptolemy's table was based in part on real experiments. Ptolemy's theory of vision consisted of rays (or flux) coming from the eye forming a cone, the vertex being within
13261-400: The east end to act as a private chapel; inside is the tomb of Christopher St Lawrence, 2nd Baron Howth , who died in 1462, and his wife, Anna Plunkett of Ratoath. Also of historic interest is a building known as The College or The Old College , on Abbey Street which was primarily constructed in the late 15th or early 16th century but also with earlier medieval elements. Drumleck Castle on
13410-713: The education system. Linguistic analyses of Irish speakers are therefore based primarily on the number of daily users in Ireland outside the education system, which in 2022 was 20,261 in the Gaeltacht and 51,707 outside it, totalling 71,968. In response to the 2021 census of Northern Ireland , 43,557 individuals stated they spoke Irish on a daily basis, 26,286 spoke it on a weekly basis, 47,153 spoke it less often than weekly, and 9,758 said they could speak Irish, but never spoke it. From 2006 to 2008, over 22,000 Irish Americans reported speaking Irish as their first language at home, with several times that number claiming "some knowledge" of
13559-469: The elevation of the north celestial pole for a few cities. Although maps based on scientific principles had been made since the time of Eratosthenes ( c. 276 – c. 195 BC ), Ptolemy improved on map projections . The first part of the Geography is a discussion of the data and of the methods he used. Ptolemy notes the supremacy of astronomical data over land measurements or travelers' reports, though he possessed these data for only
13708-543: The emperor Claudius or the emperor Nero . The 9th century Persian astronomer Abu Ma'shar al-Balkhi mistakenly presents Ptolemy as a member of Ptolemaic Egypt's royal lineage , stating that the descendants of the Alexandrine general and Pharaoh Ptolemy I Soter were wise "and included Ptolemy the Wise, who composed the book of the Almagest ". Abu Ma'shar recorded a belief that a different member of this royal line "composed
13857-425: The empirical musical relations he identified by testing pitches against each other: He was able to accurately measure relative pitches based on the ratios of vibrating lengths two separate sides of the same single string , hence which were assured to be under equal tension, eliminating one source of error. He analyzed the empirically determined ratios of "pleasant" pairs of pitches, and then synthesised all of them into
14006-468: The end of the famine, and under 17,000 by 1911. Irish is recognised by the Constitution of Ireland as the national and first official language of Republic of Ireland (English being the other official language). Despite this, almost all government business and legislative debate is conducted in English. In 1938, the founder of Conradh na Gaeilge (Gaelic League), Douglas Hyde , was inaugurated as
14155-419: The eye, and the base defining the visual field. The rays were sensitive, and conveyed information back to the observer's intellect about the distance and orientation of surfaces. Size and shape were determined by the visual angle subtended at the eye combined with perceived distance and orientation. This was one of the early statements of size-distance invariance as a cause of perceptual size and shape constancy,
14304-545: The first President of Ireland . The record of his delivering his inaugural Declaration of Office in Roscommon Irish is one of only a few recordings of that dialect. In the 2016 census, 10.5% of respondents stated that they spoke Irish, either daily or weekly, while over 70,000 people (4.2%) speak it as a habitual daily means of communication. From the foundation of the Irish Free State in 1922 (see History of
14453-528: The fishing harbour area, and some boat maintenance. There is a State Fisheries Centre, including an ice-making plant, and a dry dock. The area is active commercially, with a range of retail and leisure outlets, including multiple restaurants, two convenience stores and a post office, although the nearest supermarket is at Sutton Cross and the nearest service stations are in Baldoyle and Bayside. Howth, having once held at least seven hotels, four still as of 1990, saw
14602-498: The harbour. The earliest church on this site was built by Sitric, King of Dublin, in 1042. It was replaced around 1235 by a parish church, when that function was moved from the church on Ireland's Eye, and then, in the second, half of the 14th century, the present church was built. The building was modified in the 15th and 16th centuries, when the gables were raised, a bell cote was built and a new porch and south door were added. The St. Lawrence family, of nearby Howth Castle, also modified
14751-517: The head of a large military force, and totally defeated the Danish inhabitants in a sanguinary battle at the bridge of Evora, over a mountain stream which falls into the sea near the Baily lighthouse. This victory secured to Sir Amorey the lordship of Howth, of which his descendants have continued in possession to the present day, under the name of St. Laurence , which Almaric, third baron, assumed in fulfilment of
14900-553: The history of science". One striking error noted by Newton was an autumn equinox said to have been observed by Ptolemy and "measured with the greatest care" at 2pm on 25 September 132, when the equinox should have been observed around 9:55am the day prior. In attempting to disprove Newton, Herbert Lewis also found himself agreeing that "Ptolemy was an outrageous fraud," and that "all those result capable of statistical analysis point beyond question towards fraud and against accidental error". The charges laid by Newton and others have been
15049-599: The introduction to the Handy Tables survived separately from the tables themselves (apparently part of a gathering of some of Ptolemy's shorter writings) under the title Arrangement and Calculation of the Handy Tables . The Planetary Hypotheses ( Greek : Ὑποθέσεις τῶν πλανωμένων , lit. ' Hypotheses of the Planets ' ) is a cosmological work, probably one of the last written by Ptolemy, in two books dealing with
15198-698: The language family, is derived from the Old Irish term. Endonyms of the language in the various modern Irish dialects include: Gaeilge [ˈɡeːlʲɟə] in Galway, Gaeilg / Gaeilic / Gaeilig [ˈɡeːlʲəc] in Mayo and Ulster , Gaelainn / Gaoluinn [ˈɡeːl̪ˠən̠ʲ] in West/Cork, Kerry Munster , as well as Gaedhealaing in mid and East Kerry/Cork and Waterford Munster to reflect local pronunciation. Gaeilge also has
15347-410: The language was in use by all classes, Irish being an urban as well as a rural language. This linguistic dynamism was reflected in the efforts of certain public intellectuals to counter the decline of the language. At the end of the 19th century, they launched the Gaelic revival in an attempt to encourage the learning and use of Irish, although few adult learners mastered the language. The vehicle of
15496-472: The language. For most of recorded Irish history , Irish was the dominant language of the Irish people , who took it with them to other regions , such as Scotland and the Isle of Man , where Middle Irish gave rise to Scottish Gaelic and Manx . It was also, for a period, spoken widely across Canada , with an estimated 200,000–250,000 daily Canadian speakers of Irish in 1890. On the island of Newfoundland ,
15645-755: The last, the Deer Park Hotel, on the Howth Estate, close in April 2014, although the premises continued to trade as a bar, and base for the Deer Park golf courses and a 'FootGolf' course, and later housed refugees. The area has multiple bed-and-breakfast establishments, and Airbnb hosts. The nearest operational hotel, The Marine Hotel (formerly the Golfers Hotel and the Strand Hotel), is located at Sutton Cross, approximately 2.5 km from Howth harbour. Other hotels that have closed include The Howth Lodge Hotel (formerly
15794-709: The late 17th century. This is the subject of a picture, Howth Lighthouse, from the Needles , by George Petrie , which appears in Fisher's Drawing Room Scrap Book, 1835, with an attached poetical illustration by Letitia Elizabeth Landon . At the end of the East Pier of Howth Harbour are the Howth Harbour Lighthouse , built in the 19th century and no longer in service, and the pole-mounted light which replaced it. In Howth village are St. Mary's Church and its graveyard, overlooking
15943-500: The mathematics of music should be based on only the one specific ratio of 3:2, the perfect fifth , and believed that tunings mathematically exact to their system would prove to be melodious, if only the extremely large numbers involved could be calculated (by hand). To the contrary, Ptolemy believed that musical scales and tunings should in general involve multiple different ratios arranged to fit together evenly into smaller tetrachords (combinations of four pitch ratios which together make
16092-563: The mid-18th century, English was becoming a language of the Catholic middle class, the Catholic Church and public intellectuals, especially in the east of the country. Increasingly, as the value of English became apparent, parents sanctioned the prohibition of Irish in schools. Increasing interest in emigrating to the United States and Canada was also a driver, as fluency in English allowed
16241-555: The modern title is thought to be an Arabic corruption of the Greek name Hē Megistē Syntaxis (lit. "The greatest treatise"), as the work was presumably known in Late Antiquity . Because of its reputation, it was widely sought and translated twice into Latin in the 12th century , once in Sicily and again in Spain. Ptolemy's planetary models, like those of the majority of his predecessors, were geocentric and almost universally accepted until
16390-477: The motions of the Sun, Moon, planets, and stars. In 2023, archaeologists were able to read a manuscript which gives instructions for the construction of an astronomical tool called a meteoroscope ( μετεωροσκόπιον or μετεωροσκοπεῖον ). The text, which comes from an eighth-century manuscript which also contains Ptolemy's Analemma , was identified on the basis of both its content and linguistic analysis as being by Ptolemy. Ptolemy's second most well-known work
16539-771: The name of the language is Gaeilge , from the South Connacht form, spelled Gaedhilge prior the spelling reform of 1948, which was originally the genitive of Gaedhealg , the form used in Classical Gaelic . The modern spelling results from the deletion of the silent ⟨dh⟩ in Gaedhilge . Older spellings include Gaoidhealg [ˈɡeːʝəlˠəɡ] in Classical Gaelic and Goídelc [ˈɡoiðʲelɡ] in Old Irish . Goidelic , used to refer to
16688-463: The new immigrants to get jobs in areas other than farming. An estimated one quarter to one third of US immigrants during the Great Famine were Irish speakers. Irish was not marginal to Ireland's modernisation in the 19th century, as is often assumed. In the first half of the century there were still around three million people for whom Irish was the primary language, and their numbers alone made them
16837-420: The north. A Martello tower exists on each of these islands with another tower overlooking Howth harbour (opened as a visitor centre and Ye Olde Hurdy Gurdy Museum of Vintage Radio on 8 June 2001) and another tower at Red Rock, Sutton. These are part of a series of towers built around the coast of Ireland during the 19th century. More than half of Howth Head, and of the Howth area, totalling around 1,500 acres,
16986-639: The number now is between 20,000 and 30,000." In the 1920s, when the Irish Free State was founded, Irish was still a vernacular in some western coastal areas. In the 1930s, areas where more than 25% of the population spoke Irish were classified as Gaeltacht . Today, the strongest Gaeltacht areas, numerically and socially, are those of South Connemara , the west of the Dingle Peninsula , and northwest Donegal, where many residents still use Irish as their primary language. These areas are often referred to as
17135-461: The observations were taken at 12:30pm. The overall quality of Ptolemy's observations has been challenged by several modern scientists, but prominently by Robert R. Newton in his 1977 book The Crime of Claudius Ptolemy , which asserted that Ptolemy fabricated many of his observations to fit his theories. Newton accused Ptolemy of systematically inventing data or doctoring the data of earlier astronomers, and labelled him "the most successful fraud in
17284-498: The other official language, if not already passed in both official languages. In November 2016, RTÉ reported that over 2.3 million people worldwide were learning Irish through the Duolingo app. Irish president Michael D. Higgins officially honoured several volunteer translators for developing the Irish edition, and said the push for Irish language rights remains an "unfinished project". There are rural areas of Ireland where Irish
17433-539: The political party holding power in the Stormont Parliament , the Ulster Unionist Party (UUP), was hostile to the language. The context of this hostility was the use of the language by nationalists. In broadcasting, there was an exclusion on the reporting of minority cultural issues, and Irish was excluded from radio and television for almost the first fifty years of the previous devolved government. After
17582-401: The radius of the sphere of the fixed stars was 20 000 times the radius of the Earth. The work is also notable for having descriptions on how to build instruments to depict the planets and their movements from a geocentric perspective, much as an orrery would have done for a heliocentric one, presumably for didactic purposes. The Analemma is a short treatise where Ptolemy provides
17731-486: The reappearance of heliocentric models during the scientific revolution . Under the scrutiny of modern scholarship, and the cross-checking of observations contained in the Almagest against figures produced through backwards extrapolation, various patterns of errors have emerged within the work. A prominent miscalculation is Ptolemy's use of measurements that he claimed were taken at noon, but which systematically produce readings now shown to be off by half an hour, as if
17880-487: The relationship between the three Goidelic languages (Irish, Scottish Gaelic and Manx). Gaelic is a collective term for the Goidelic languages, and when the context is clear it may be used without qualification to refer to each language individually. When the context is specific but unclear, the term may be qualified, as Irish Gaelic, Scottish Gaelic or Manx Gaelic. Historically the name "Erse" ( / ɜːr s / URS )
18029-432: The requirement for entrance to the public service was changed to proficiency in just one official language. Nevertheless, Irish remains a required subject of study in all schools in the Republic of Ireland that receive public money (see Education in the Republic of Ireland ). Teachers in primary schools must also pass a compulsory examination called Scrúdú Cáilíochta sa Ghaeilge . As of 2005, Garda Síochána recruits need
18178-625: The revival was the Gaelic League ( Conradh na Gaeilge ), and particular emphasis was placed on the folk tradition, which in Irish is particularly rich. Efforts were also made to develop journalism and a modern literature. Although it has been noted that the Catholic Church played a role in the decline of the Irish language before the Gaelic Revival, the Protestant Church of Ireland also made only minor efforts to encourage use of Irish in
18327-405: The secondary literature, while noting that issues with the accuracy of Ptolemy's observations had long been known. Other authors have pointed out that instrument warping or atmospheric refraction may also explain some of Ptolemy's observations at a wrong time. In 2022 the first Greek fragments of Hipparchus' lost star catalog were discovered in a palimpsest and they debunked accusations made by
18476-455: The site close to the demesne gate immediately sold on again for development, to Glenveagh Properties. Howth Head is one of the dominant features of Dublin Bay , with a number of peaks, the highest of which is Black Linn. In one area, near Shielmartin, there is a small peat bog, the "Bog of the Frogs". The wilder parts of Howth can be accessed by a network of paths (many are rights of way) and much of
18625-474: The spanning of more than 800 years; however, many astronomers have for centuries suspected that some of his models' parameters were adopted independently of observations. Ptolemy presented his astronomical models alongside convenient tables, which could be used to compute the future or past position of the planets. The Almagest also contains a star catalogue , which is a version of a catalogue created by Hipparchus . Its list of forty-eight constellations
18774-451: The spheres ). Although Ptolemy's Harmonics never had the influence of his Almagest or Geography , it is nonetheless a well-structured treatise and contains more methodological reflections than any other of his writings. In particular, it is a nascent form of what in the following millennium developed into the scientific method, with specific descriptions of the experimental apparatus that he built and used to test musical conjectures, and
18923-440: The structure of the universe and the laws that govern celestial motion . Ptolemy goes beyond the mathematical models of the Almagest to present a physical realization of the universe as a set of nested spheres, in which he used the epicycles of his planetary model to compute the dimensions of the universe. He estimated the Sun was at an average distance of 1 210 Earth radii (now known to actually be ~23 450 radii), while
19072-517: The subject of wide discussions and received significant push back from other scholars against the findings. Owen Gingerich , while agreeing that the Almagest contains "some remarkably fishy numbers", including in the matter of the 30-hour displaced equinox, which he noted aligned perfectly with predictions made by Hipparchus 278 years earlier, rejected the qualification of fraud. Objections were also raised by Bernard Goldstein , who questioned Newton's findings and suggested that he had misunderstood
19221-496: The supremacy of mathematical knowledge over other forms of knowledge. Like Aristotle before him, Ptolemy classifies mathematics as a type of theoretical philosophy; however, Ptolemy believes mathematics to be superior to theology or metaphysics because the latter are conjectural while only the former can secure certain knowledge. This view is contrary to the Platonic and Aristotelian traditions, where theology or metaphysics occupied
19370-573: The third part of the Geography , Ptolemy gives instructions on how to create maps both of the whole inhabited world ( oikoumenē ) and of the Roman provinces, including the necessary topographic lists, and captions for the maps. His oikoumenē spanned 180 degrees of longitude from the Blessed Islands in the Atlantic Ocean to the middle of China , and about 80 degrees of latitude from Shetland to anti-Meroe (east coast of Africa ); Ptolemy
19519-705: The vacancy to which they are appointed. This requirement is laid down by the University College Galway Act, 1929 (Section 3). In 2016, the university faced controversy when it announced the planned appointment of a president who did not speak Irish. Misneach staged protests against this decision. The following year the university announced that Ciarán Ó hÓgartaigh , a fluent Irish speaker, would be its 13th president. He assumed office in January 2018; in June 2024, he announced he would be stepping down as president at
19668-399: The views from the summit, to walk the piers, and to taste locally sourced seafood. Howth is a common area for birdwatching and sailing , and is also popular with anglers. Fish like cod and ray can be caught from Howth's rocky shore marks. Sea mammals, such as seals, are common sights in and near the harbour. It used to be popular to feed the seals but authorities banned the practice for
19817-594: The work of such writers as Geoffrey Keating , is said to date from the 17th century, and was the medium of popular literature from that time on. From the 18th century on, the language lost ground in the east of the country. The reasons behind this shift were complex but came down to a number of factors: The change was characterised by diglossia (two languages being used by the same community in different social and economic situations) and transitional bilingualism (monoglot Irish-speaking grandparents with bilingual children and monoglot English-speaking grandchildren). By
19966-461: Was Ptolemais Hermiou , a Greek city in the Thebaid region of Egypt (now El Mansha, Sohag Governorate ). This attestation is quite late, however, and there is no evidence to support it. It is known that Ptolemy lived in or around the city of Alexandria , in the Roman province of Egypt under Roman rule . He had a Latin name, Claudius, which is generally taken to imply he was a Roman citizen . He
20115-457: Was a minor trading port from at least the 14th century, with both health and duty collection officials supervising from Dublin, although the harbour was not built until the early 19th century. A popular tale concerns the clan leader and sometime pirate Gráinne O'Malley , who was rebuffed in 1576 while attempting a courtesy visit to Howth Castle , home of the Earl of Howth . In retaliation, she abducted
20264-523: Was also sometimes used in Scots and then in English to refer to Irish; as well as Scottish Gaelic. Written Irish is first attested in Ogham inscriptions from the 4th century AD, a stage of the language known as Primitive Irish . These writings have been found throughout Ireland and the west coast of Great Britain. Primitive Irish underwent a change into Old Irish through the 5th century. Old Irish, dating from
20413-431: Was an Alexandrian mathematician , astronomer , astrologer , geographer , and music theorist who wrote about a dozen scientific treatises , three of which were important to later Byzantine , Islamic , and Western European science. The first was his astronomical treatise now known as the Almagest , originally entitled Mathematical Treatise ( Greek : Μαθηματικὴ Σύνταξις , Mathēmatikḗ Syntaxis ). The second
20562-403: Was chosen as the location for the harbour for the mail packet (postal service) ship. Construction began in 1807. One of the arguments used against Howth by the advocates of Dún Laoghaire was that coaches might be raided in the badlands of Sutton (at the time Sutton was open countryside). However, due to silting , the harbour needed frequent dredging to accommodate the packet and the service
20711-519: Was done on the much-delayed project in 1986), with distinct fishing and leisure areas formed, and the installation of a modern ice-making facility. A new lifeboat house was later constructed, and Howth is today home to units of both the RNLI (lifeboat service) and the Irish Coastguard. In 2019, Howth Castle and its demesne, including Ireland's Eye, were sold to Tetrarch Investment group, with an element of
20860-643: Was enacted 1 July 2019 and is an 18-page document that adheres to the guidelines of the Official Languages Act 2003 . The purpose of the Scheme is to provide services through the mediums of Irish and/or English. According to the Department of the Taoiseach, it is meant to "develop a sustainable economy and a successful society, to pursue Ireland's interests abroad, to implement the Government's Programme and to build
21009-659: Was establishing itself as the primary language. Irish speakers had first arrived in Australia in the late 18th century as convicts and soldiers, and many Irish-speaking settlers followed, particularly in the 1860s. New Zealand also received some of this influx. Argentina was the only non-English-speaking country to receive large numbers of Irish emigrants, and there were few Irish speakers among them. Ptolemy Claudius Ptolemy ( / ˈ t ɒ l ə m i / ; Ancient Greek : Πτολεμαῖος , Ptolemaios ; Latin : Claudius Ptolemaeus ; c. 100 – c. 170 AD)
21158-614: Was familiar with Greek philosophers and used Babylonian observations and Babylonian lunar theory. In half of his extant works, Ptolemy addresses a certain Syrus, a figure of whom almost nothing is known but who likely shared some of Ptolemy's astronomical interests. Ptolemy died in Alexandria c. 168 . Ptolemy's Greek name , Ptolemaeus ( Πτολεμαῖος , Ptolemaîos ), is an ancient Greek personal name . It occurs once in Greek mythology and
21307-561: Was his cottage home from 1880 to 1883. The plaque contains the couplet “I have spread my dreams under your feet/ Tread softly because you tread on my dreams” from his poem ' Aedh Wishes for the Cloths of Heaven ' (1899). Howth would feature in Yeats writings. The first time is the 1893 essay 'Village Ghosts' recounting the paranormal folklore of the village and the second is in the poem 'Beautiful Lofty Things' (1938); " Maud Gonne at Howth station waiting
21456-464: Was not based solely on data from Hipparchus’ Catalogue. ...
