102-513: A bulletin board ( pinboard , pin board , noticeboard , or notice board in British English) is a surface intended for the posting of public messages, for example, to advertise items wanted or for sale, announce events, or provide information. Bulletin boards are often made of a material such as cork to facilitate addition and removal of messages, as well as a writing surface such as blackboard or whiteboard . A bulletin board which combines
204-718: A gas mixture similar to the air, making them behave as authentic "pads," which contributes to the capability of cork to recover after compression. There are about 2,200,000 hectares of cork oak ( Quercus suber ) forest in the Mediterranean basin , the native area of the species. The most extensively managed habitats are in Portugal (34%) and in Spain (27%). Annual production is about 300,000 tons; 49.6% from Portugal, 30.5% from Spain, 5.8% from Morocco , 4.9% from Algeria , 3.5% from Tunisia , 3.1% from Italy , and 2.6% from France . Once

TCA is the main documented cause of cork taint in wine. However, some in the wine industry say natural cork stoppers are important because they allow oxygen to interact with wine for proper aging, and are best suited for wines purchased with
408-536: A 'strongman' was often the best solution. Athens fell under a tyranny in the second half of the 6th century BC. When this tyranny was ended, the Athenians founded the world's first democracy as a radical solution to prevent the aristocracy regaining power. A citizens' assembly (the Ecclesia ), for the discussion of city policy, had existed since the reforms of Draco in 621 BC; all citizens were permitted to attend after

The cellular wall consists of a thin, lignin-rich middle lamella (internal primary wall), a thick secondary wall made up from alternating suberin and wax lamella, and a thin tertiary wall of polysaccharides. Some studies suggest that the secondary wall is lignified, and therefore, may not consist exclusively of suberin and waxes. The cells of cork are filled with
714-495: A coalition of 31 Greek city states, including Athens and Sparta, determined to resist the Persian invaders. At the same time, Greek Sicily was invaded by a Carthaginian force. In 480 BC, the first major battle of the invasion was fought at Thermopylae , where a small rearguard of Greeks, led by three hundred Spartans, held a crucial pass guarding the heart of Greece for several days; at the same time Gelon , tyrant of Syracuse, defeated

For example, to produce 1,000 cork stoppers 1.5 kg CO 2 are emitted, but to produce the same amount of plastic stoppers 14 kg of CO 2 are emitted and for the same amount of aluminium screw caps 37 kg CO 2 are emitted. The Chinese cork oak is native to East Asia and is cultivated in a limited extent in China; the cork produced is considered inferior to Q. suber and are used to produce agglomerated cork products. The so-called "cork trees" ( Phellodendron ) are unrelated to

Only free, land-owning, native born men could be citizens entitled to the full protection of the law in a city-state. In most city-states, unlike the situation in Rome , social prominence did not allow special rights. Sometimes families controlled public religious functions, but this ordinarily did not give any extra power in
1122-514: A decisive victory, and in 447 lost Boeotia again. Athens and Sparta signed the Thirty Years' Peace in the winter of 446/5, ending the conflict. Despite the treaty, Athenian relations with Sparta declined again in the 430s, and in 431 BC the Peloponnesian War began. The first phase of the war saw a series of fruitless annual invasions of Attica by Sparta, while Athens successfully fought

#17330851894521224-570: A decline in use as wine-stoppers due to the increase in the use of synthetic alternatives, cork wine-stoppers are making a comeback and currently represent approximately 60% of wine-stoppers in 2016. Because of the cellular structure of cork, it is easily compressed upon insertion into a bottle and will expand to form a tight seal. The interior diameter of the neck of glass bottles tends to be inconsistent, making this ability to seal through variable contraction and expansion an important attribute. However, unavoidable natural flaws, channels, and cracks in
1326-436: A group of city-states allied themselves to defend Greece, the vast majority of poleis remained neutral, and after the Persian defeat, the allies quickly returned to infighting. Thus, the major peculiarities of the ancient Greek political system were its fragmented nature (and that this does not particularly seem to have tribal origin), and the particular focus on urban centers within otherwise tiny states. The peculiarities of
1428-423: A massive expansion, particularly due to the development of several cork-based agglomerates. In China , Egypt , Babylon , and Persia from about 3000 BC, cork was already used for sealing containers , fishing equipment, and domestic applications. In ancient Greece (1600 to 1100 years BC) cork was used in footwear , to manufacture a type of sandals attached to the foot by straps, generally leather and with
1530-414: A number of Internet forums or discussion groups. An online board can serve the same purpose as a physical bulletin board, with the added benefit of not being bound by geographical location. Magnet boards, or magnetic bulletin boards, are a popular substitute for cork boards because they lack the problem of board deterioration from the insertion and removal of pins over time. Cork (material) Cork
1632-550: A one-year life cycle analysis comparison with plastic stoppers and aluminum screw caps. Ancient Greece Ancient Greece ( Ancient Greek : Ἑλλάς , romanized : Hellás ) was a northeastern Mediterranean civilization, existing from the Greek Dark Ages of the 12th–9th centuries BC to the end of classical antiquity ( c. 600 AD ), that comprised a loose collection of culturally and linguistically related city-states and other territories. Prior to

Bulletin boards can also be entirely in the digital domain and placed on computer networks so people can leave and erase messages for other people to read and see, as in a bulletin board system . Bulletin boards are particularly prevalent at universities. They are used by many sports groups and extracurricular groups and anything from local shops to official notices. Dormitory corridors, well-trafficked hallways, lobbies, and freestanding kiosks often have cork boards attached to facilitate
1836-745: A result of Epaminondas ' liberation of Messenia from Spartan rule, the helot system there came to an end and the helots won their freedom. However, it did continue to persist in Laconia until the 2nd century BC. For most of Greek history, education was private, except in Sparta. During the Hellenistic period, some city-states established public schools . Only wealthy families could afford a teacher. Boys learned how to read, write and quote literature. They also learned to sing and play one musical instrument and were trained as athletes for military service. They studied not for
1938-477: A sole in cork or leather. In the second century AD, a Greek physician, Dioscorides , noted several medical applications of cork, mainly for hair loss treatment. Nowadays, the majority of people know cork for its use as stoppers in wine bottles . The innovation of using cork as stopper can be traced back to the late 17th century, attributed to Dom Pierre Pérignon . Cork stoppers were adopted in 1729 by Ruinart and in 1973 by Moët et Chandon . Cork presents
2040-516: A special type of slaves called helots . Helots were Messenians enslaved en masse during the Messenian Wars by the state and assigned to families where they were forced to stay. Helots raised food and did household chores so that women could concentrate on raising strong children while men could devote their time to training as hoplites . Their masters treated them harshly, and helots revolted against their masters several times. In 370/69 BC, as
2142-481: A suitable material for fishing floats and buoys, as well as handles for fishing rods (as an alternative to neoprene ). Granules of cork can also be mixed into concrete . The composites made by mixing cork granules and cement have lower thermal conductivity, lower density, and good energy absorption. Some of the property ranges of the composites are density (400–1500 kg/m ), compressive strength (1–26 MPa), and flexural strength (0.5–4.0 MPa). As late as

Although the First Macedonian War was inconclusive, the Romans, in typical fashion, continued to fight Macedon until it was completely absorbed into the Roman Republic (by 149 BC). In the east, the unwieldy Seleucid Empire gradually disintegrated, although a rump survived until 64 BC, whilst the Ptolemaic Kingdom continued in Egypt until 30 BC when it too
2346-669: A year, the Thirty had been overthrown. The first half of the fourth century saw the major Greek states attempt to dominate the mainland; none were successful, and their resulting weakness led to a power vacuum which would eventually be filled by Macedon under Philip II and then Alexander the Great. In the immediate aftermath of the Peloponnesian war, Sparta attempted to extend their own power, leading Argos, Athens, Corinth, and Thebes to join against them. Aiming to prevent any single Greek state gaining

It is the phellem layer of bark tissue which is harvested for commercial use primarily from Quercus suber (the cork oak), which is native to southwest Europe and northwest Africa . Cork is composed of suberin , a hydrophobic substance. Because of its impermeable, buoyant, elastic, and fire retardant properties, it is used in a variety of products,
2550-423: Is gaining popularity as a non-allergenic, easy-to-handle and safe alternative to petrochemical-based insulation products. Cork is also used to make vinyl record slipmats, due to its ability to not attract dust. They also dampen static and vibrations. Sheets of cork, also often the by-product of stopper production, are used to make bulletin boards as well as floor and wall tiles . Cork's low density makes it

Regionalism and regional conflicts were prominent features of ancient Greece. Cities tended to be located in valleys between mountains, or on coastal plains, and dominated a certain area around them. In the south lay the Peloponnese , consisting of

Bark from initial harvests can be used to make flooring, shoes, insulation and other industrial products. Subsequent extractions usually occur at intervals of nine years, though it can take up to thirteen for the cork to reach an acceptable size. If
2958-475: Is unclear exactly how this change occurred. For instance, in Athens, the kingship had been reduced to a hereditary, lifelong chief magistracy ( archon ) by c. 1050 BC; by 753 BC this had become a decennial, elected archonship; and finally by 683 BC an annually elected archonship. Through each stage, more power would have been transferred to the aristocracy as a whole, and away from a single individual. Inevitably,

Their scope is further limited by a focus on political, military and diplomatic history, ignoring economic and social history. The archaic period, lasting from approximately 800 to 500 BC, saw the culmination of political and social developments which had begun in the Greek dark age, with the polis (city-state) becoming
3366-727: The Archaic period and the colonization of the Mediterranean Basin. This was followed by the age of Classical Greece , from the Greco-Persian Wars to the death of Alexander the Great in 323 BC, and which included the Golden Age of Athens and the Peloponnesian War . The unification of Greece by Macedon under Philip II and subsequent conquest of the Achaemenid Empire by Alexander the Great spread Hellenistic civilization across
3468-656: The Archaic period , the Greek population grew beyond the capacity of the limited arable land of Greece proper, resulting in the large-scale establishment of colonies elsewhere: according to one estimate, the population of the widening area of Greek settlement increased roughly tenfold from 800 BC to 400 BC, from 800,000 to as many as 7 + 1 ⁄ 2 -10 million. This was not simply for trade, but also to found settlements. These Greek colonies were not, as Roman colonies were, dependent on their mother-city, but were independent city-states in their own right. Greeks settled outside of Greece in two distinct ways. The first

Following the Athenian surrender, Sparta installed an oligarchic regime, the Thirty Tyrants , in Athens, one of a number of Spartan-backed oligarchies which rose to power after the Peloponnesian war. Spartan predominance did not last: after only
3672-653: The Boeotian League and finally to the League of Corinth led by Macedon . This period was shaped by the Greco-Persian Wars , the Peloponnesian War , and the Rise of Macedon . Following the Classical period was the Hellenistic period (323–146 BC), during which Greek culture and power expanded into the Near and Middle East from the death of Alexander until the Roman conquest. Roman Greece
3774-564: The Delian League gradually transformed from a defensive alliance of Greek states into an Athenian empire, as Athens' growing naval power intimidated the other league states. Athens ended its campaigns against Persia in 450, after a disastrous defeat in Egypt in 454, and the death of Cimon in action against the Persians on Cyprus in 450. As the Athenian fight against the Persian empire waned, conflict grew between Athens and Sparta. Suspicious of

Chalcidice was settled early on by southern Greek colonists and was considered part of the Greek world, while from the late 2nd millennium BC substantial Greek settlement also occurred on the eastern shores of the Aegean , in Anatolia . During

In Western history , the era of classical antiquity was immediately followed by the Early Middle Ages and the Byzantine period. Three centuries after the decline of Mycenaean Greece during the Bronze Age Collapse , Greek urban poleis began to form in the 8th century BC, ushering in
4080-449: The poleis grouped themselves into leagues, membership of which was in a constant state of flux. Later in the Classical period, the leagues would become fewer and larger, be dominated by one city (particularly Athens , Sparta and Thebes ); and often poleis would be compelled to join under threat of war (or as part of a peace treaty). Even after Philip II of Macedon conquered the heartlands of ancient Greece, he did not attempt to annex

The war turned after Athenian victories led by Cleon at Pylos and Sphakteria , and Sparta sued for peace, but the Athenians rejected the proposal. The Athenian failure to regain control of Boeotia at Delium and Brasidas ' successes in northern Greece in 424 improved Sparta's position after Sphakteria. After

Many Greeks migrated to Alexandria, Antioch and the many other new Hellenistic cities founded in Alexander's wake, as far away as present-day Afghanistan and Pakistan , where the Greco-Bactrian Kingdom and the Indo-Greek Kingdom survived until
4692-460: The Greek colonies Syracusae ( Συράκουσαι ), Neapolis ( Νεάπολις ), Massalia ( Μασσαλία ) and Byzantion ( Βυζάντιον ). These colonies played an important role in the spread of Greek influence throughout Europe and also aided in the establishment of long-distance trading networks between the Greek city-states, boosting the economy of ancient Greece . Ancient Greece consisted of several hundred relatively independent city-states ( poleis ). This

Supported by troops sent from Athens and Eretria , they advanced as far as Sardis and burnt the city before being driven back by a Persian counterattack. The revolt continued until 494, when the rebelling Ionians were defeated. Darius did not forget that Athens had assisted
4896-476: The Greek system are further evidenced by the colonies that they set up throughout the Mediterranean , which, though they might count a certain Greek polis as their 'mother' (and remain sympathetic to her), were completely independent of the founding city. Inevitably smaller poleis might be dominated by larger neighbors, but conquest or direct rule by another city-state appears to have been quite rare. Instead
4998-803: The Greeks began 250 years of expansion, settling colonies in all directions. To the east, the Aegean coast of Asia Minor was colonized first, followed by Cyprus and the coasts of Thrace , the Sea of Marmara and south coast of the Black Sea . Eventually, Greek colonization reached as far northeast as present-day Ukraine and Russia ( Taganrog ). To the west the coasts of Illyria , Southern Italy (called " Magna Graecia ") were settled, followed by Southern France , Corsica , and even eastern Spain . Greek colonies were also founded in Egypt and Libya . Modern Syracuse , Naples , Marseille and Istanbul had their beginnings as
5100-423: The Greeks were very aware of their tribal origins; Herodotus was able to extensively categorise the city-states by tribe. Yet, although these higher-level relationships existed, they seem to have rarely had a major role in Greek politics. The independence of the poleis was fiercely defended; unification was something rarely contemplated by the ancient Greeks. Even when, during the second Persian invasion of Greece,

Some consumers may have conceptions about screw caps being representative of lower quality wines, due to their cheaper price; however, in Australia, for example, much of the non-sparkling wine production now uses these Stelvin caps as a cork alternative, although some have recently switched back to cork citing issues using screw caps. The alternatives to cork have both advantages and disadvantages. For example, screwtops are generally considered to offer
5712-575: The ancient Greeks did not think in terms of race . Most families owned slaves as household servants and laborers, and even poor families might have owned a few slaves. Owners were not allowed to beat or kill their slaves. Owners often promised to free slaves in the future to encourage slaves to work hard. Unlike in Rome, freedmen did not become citizens. Instead, they were mixed into the population of metics , which included people from foreign countries or other city-states who were officially allowed to live in

Antigonus attempted to expand his territory by attacking the other successor kingdoms until they joined against him, and he was killed at the Battle of Ipsus in 301 BC. His son Demetrius spent many years in Seleucid captivity, and his son, Antigonus II , only reclaimed the Macedonian throne around 276. Meanwhile, the Seleucid kingdom gave up territory in
7650-475: The extractor must not damage the underlying phellogen or the tree will be harmed. To free the cork from the tree, the extractor pushes the handle of the axe into the rulers. A good extractor needs to use a firm but precise touch in order to free a large amount of cork without damaging the product or tree. These freed portions of the cork are called planks . The planks are usually carried off by hand since cork forests are rarely accessible to vehicles. The cork
7752-464: The founding of Greek colonies around the Mediterranean, with Euboean settlements at Al-Mina in the east as early as 800 BC, and Ischia in the west by 775. Increasing contact with non-Greek peoples in this period, especially in the Near East, inspired developments in art and architecture, the adoption of coinage, and the development of the Greek alphabet. Athens developed its democratic system over
7854-569: The government. In Athens, the population was divided into four social classes based on wealth. People could change classes if they made more money. In Sparta, all male citizens were called homoioi , meaning "peers". However, Spartan kings, who served as the city-state's dual military and religious leaders, came from two families. Women in Ancient Greece appear to have primarily performed domestic tasks, managed households, and borne and reared children. Slaves had no power or status. Slaves had
7956-535: The increasing Athenian power funded by the Delian League, Sparta offered aid to reluctant members of the League to rebel against Athenian domination. These tensions were exacerbated in 462 BC when Athens sent a force to aid Sparta in overcoming a helot revolt, but this aid was rejected by the Spartans. In the 450s, Athens took control of Boeotia, and won victories over Aegina and Corinth. However, Athens failed to win
8058-479: The intent to age. Stoppers which resemble natural cork very closely can be made by isolating the suberin component of the cork from the undesirable lignin , mixing it with the same substance used for contact lenses and an adhesive, and molding it into a standardized product, free of TCA or other undesirable substances. Composite corks with real cork veneers are used in cheaper wines. Celebrated Australian wine writer and critic James Halliday has written that since
8160-514: The loss of Messenia's fertile land and the helot workforce it provided. The rising power of Thebes led Sparta and Athens to join forces; in 362 they were defeated by Thebes at the Battle of Mantinea . In the aftermath of Mantinea, none of the major Greek states were able to dominate. Though Thebes had won the battle, their general Epaminondas was killed, and they spent the following decades embroiled in wars with their neighbours; Athens, meanwhile, saw its second naval alliance, formed in 377, collapse in
8262-418: The mid-17th century, French vintners did not use cork stoppers, using instead oil-soaked rags stuffed into the necks of bottles. Wine corks can be made of either a single piece of cork, or composed of particles, as in champagne corks; corks made of granular particles are called "agglomerated corks". Natural cork closures are used for about 80% of the 20 billion bottles of wine produced each year. After
8364-495: The mid-350s. The power vacuum in Greece after the Battle of Mantinea was filled by Macedon, under Philip II . In 338 BC, he defeated a Greek alliance at the Battle of Chaeronea , and subsequently formed the League of Corinth . Philip planned to lead the League to invade Persia, but was murdered in 336 BC. His son Alexander the Great was left to fulfil his father's ambitions. After campaigns against Macedon's western and northern enemies, and those Greek states that had broken from
8466-539: The most common of which is wine stoppers . The montado landscape of Portugal produces approximately half of the cork harvested annually worldwide, with Corticeira Amorim being the leading company in the industry. Cork was examined microscopically by Robert Hooke , which led to his discovery and naming of the cell . Cork composition varies depending on geographic origin, climate and soil conditions, genetic origin, tree dimensions, age (virgin or reproduction), and growth conditions. However, in general, cork
8568-443: The most important unit of political organisation in Greece. The absence of powerful states in Greece after the collapse of Mycenaean power, and the geography of Greece, where many settlements were separated from their neighbours by mountainous terrain, encouraged the development of small independent city-states. Several Greek states saw tyrants rise to power in this period, most famously at Corinth from 657 BC. The period also saw
8670-462: The posting of notices. At some universities, lampposts, bollards, trees, and walls often become impromptu posting sites in areas where official boards are sparse in number. Internet forums are a replacement for traditional bulletin boards. Online bulletin boards are sometimes referred to as message boards. The terms bulletin board, message board and even Internet forum are interchangeable, although often one bulletin board or message board can contain
8772-410: The power of the rich and the poor. In the middle of the sixth century, Pisistratus established himself as a tyrant, and after his death in 527 his son Hippias inherited his position; by the end of the sixth century he had been overthrown and Cleisthenes carried out further democratising reforms. In Sparta, a political system with two kings, a council of elders , and five ephors developed over
8874-565: The product is of high quality it is known as gentle cork (Portuguese cortiça amadia , but also cortiça secundeira only if it is the second time; Spanish corcho segundero , also restricted to the second time ), and, ideally, is used to make stoppers for wine and champagne bottles. Cork's elasticity combined with its near-impermeability makes it suitable as a material for bottle stoppers , especially for wine bottles . Cork stoppers represent about 60% of all cork based production. Cork has an almost zero Poisson's ratio , which means
8976-497: The radius of a cork does not change significantly when squeezed or pulled. Cork is an excellent gasket material. Some carburetor float bowl gaskets are made of cork, for example. Cork is also an essential element in the production of badminton shuttlecocks . Cork's bubble-form structure and natural fire retardant make it suitable for acoustic and thermal insulation in house walls, floors, ceilings, and facades. The by-product of more lucrative stopper production, corkboard,
9078-613: The reforms of Solon (early 6th century), but the poorest citizens could not address the assembly or run for office. With the establishment of the democracy, the assembly became the de jure mechanism of government; all citizens had equal privileges in the assembly. However, non-citizens, such as metics (foreigners living in Athens) or slaves , had no political rights at all. After the rise of democracy in Athens, other city-states founded democracies. However, many retained more traditional forms of government. As so often in other matters, Sparta
9180-420: The regions of Laconia (southeast), Messenia (southwest), Elis (west), Achaia (north), Korinthia (northeast), Argolis (east), and Arcadia (center). These names survive to the present day as regional units of modern Greece , though with somewhat different boundaries. Mainland Greece to the north, nowadays known as Central Greece , consisted of Aetolia and Acarnania in the west, Locris , Doris , and Phocis in
9282-518: The right to have a family and own property, subject to their master's goodwill and permission, but they had no political rights. By 600 BC, chattel slavery had spread in Greece. By the 5th century BC, slaves made up one-third of the total population in some city-states. Between 40–80% of the population of Classical Athens were slaves. Slaves outside of Sparta almost never revolted because they were made up of too many nationalities and were too scattered to organize. However, unlike later Western culture ,
9384-448: The state. City-states legally owned slaves. These public slaves had a larger measure of independence than slaves owned by families, living on their own and performing specialized tasks. In Athens, public slaves were trained to look out for counterfeit coinage , while temple slaves acted as servants of the temple's deity and Scythian slaves were employed in Athens as a police force corralling citizens to political functions. Sparta had
9486-669: The territories they controlled. The most important of these rulers in the decades after Alexander's death were Antigonus I and his son Demetrius in Macedonia and the rest of Greece, Ptolemy in Egypt, and Seleucus I in Syria and the former Persian empire; smaller Hellenistic kingdoms included the Attalids in Anatolia and the Greco-Bactrian kingdom . In the early part of the Hellenistic period,
9588-510: The territory or unify it into a new province, but compelled most of the poleis to join his own Corinthian League . Initially many Greek city-states seem to have been petty kingdoms; there was often a city official carrying some residual, ceremonial functions of the king ( basileus ), e.g., the archon basileus in Athens. However, by the Archaic period and the first historical consciousness, most had already become aristocratic oligarchies . It
9690-608: The time of Alexander I of Macedon , the Argead kings of Macedon started to expand into Upper Macedonia , lands inhabited by independent Macedonian tribes like the Lyncestae , Orestae and the Elimiotae and to the west, beyond the Axius river , into Eordaia , Bottiaea , Mygdonia , and Almopia , regions settled by Thracian tribes. To the north of Macedonia lay various non-Greek peoples such as
9792-421: The trees are about 25 years old the cork is traditionally stripped from the trunks every nine years, with the first two harvests generally producing lower quality cork ( male cork or virgin cork ). The trees live for about 300 years. The cork industry is generally regarded as environmentally friendly. Cork production is generally considered sustainable because the cork tree is not cut down to obtain cork; only
9894-529: Was a notable exception to the rest of Greece, ruled through the whole period by not one, but two hereditary monarchs. This was a form of diarchy . The Kings of Sparta belonged to the Agiads and the Eurypontids, descendants respectively of Eurysthenes and Procles . Both dynasties' founders were believed to be twin sons of Aristodemus , a Heraclid ruler. However, the powers of these kings were held in check by both
9996-460: Was a situation unlike that in most other contemporary societies, which were either tribal or kingdoms ruling over relatively large territories. Undoubtedly, the geography of Greece —divided and sub-divided by hills, mountains, and rivers—contributed to the fragmentary nature of ancient Greece. On the one hand, the ancient Greeks had no doubt that they were "one people"; they had the same religion , same basic culture, and same language. Furthermore,
10098-732: Was conquered by the Romans. The Aetolian league grew wary of Roman involvement in Greece, and sided with the Seleucids in the Roman–Seleucid War ; when the Romans were victorious, the league was effectively absorbed into the Republic. Although the Achaean league outlasted both the Aetolian league and Macedon, it was also soon defeated and absorbed by the Romans in 146 BC, bringing Greek independence to an end. The Greek peninsula came under Roman rule during
10200-422: Was directed at Portuguese and Spanish cork suppliers who were suspected of deliberately supplying bad cork to non- EEC wine makers to help prevent cheap imports. Cheaper wine makers developed the aluminium "Stelvin" cap with a polypropylene stopper wad. More expensive wines and carbonated varieties continued to use cork, although much closer attention was paid to the quality. Even so, some high premium makers prefer
10302-417: Was in permanent settlements founded by Greeks, which formed as independent poleis. The second form was in what historians refer to as emporia ; trading posts which were occupied by both Greeks and non-Greeks and which were primarily concerned with the manufacture and sale of goods. Examples of this latter type of settlement are found at Al Mina in the east and Pithekoussai in the west. From about 750 BC
10404-590: Was preceded by the Greek Dark Ages ( c. 1200 – c. 800 BC ), archaeologically characterised by the protogeometric and geometric styles of designs on pottery. Following the Dark Ages was the Archaic Period , beginning around the 8th century BC, which saw early developments in Greek culture and society leading to the Classical Period from the Persian invasion of Greece in 480 BC until
