The tradition of philosophy in Ancient Greece also added to the literary works. Greek learning has had a profound influence on Western and Middle Eastern civilisation. The works of Socrates, Plato, Aristotle, and other Greek philosophers profoundly influenced Classical thought, the Islamic Golden Age, and the Renaissance.
In astronomy, the Pythagoreans were well aware of the periodic numerical relations of the planets, moon, and sun. The celestial spheres of the planets were thought to produce a harmony called the music of the spheres. These ideas, as well as the ideas of the perfect solids, would later be used by Johannes Kepler in his attempt to formulate a model of the solar system in his work The Harmony of the Worlds. Pythagoreans also believed that the earth itself was in motion.
As for the Archaic period of Greek art, painted pottery and sculpture are almost the only forms of art which have survived in any quantity. Painting was in its infancy during this period, and no examples of it have survived. Although coins were invented in the mid 7th century BC, they were not common in most of Greece until the 5th century
The Greeks decided at a very early period that the human form was the most important subject for artistic endeavour. Since they saw their gods as having human form, there was no distinction between the sacred and the secular in art — the human body was both secular and sacred. A male nude could just as easily be Apollo or Herakles or that year's current Olympic boxing champion. In the Archaic Period the most important sculptural form was the kouros (plural kouroi), the standing male nude (See for example Biton and Kleobis). The kore (plural korai), or standing female figure, was also common, but since Greek society did not permit the public display of female nudity until the 4th century BC, the kore is considered to be of less importance in the development of sculpture.
The subsequent biographical traditions of Pythagoras reflect this split: they portray him alternately as a down-to-earth political reformer, a pioneering scientist, or a wild shaman-figure. The truth no doubt lies somewhere in between.
The great majority of Greek buildings have not survived to this day: either they had been pillaged in war, had been looted for building materials or had been destroyed in Greece’s many earthquakes. Only a handful of temples, such as the Parthenon and the Temple of Hephaestus in Athens, have been spared. Of the four Wonders of the World created by the Greeks — the Statue of Zeus at Olympia, the Temple of Artemis at Ephesus, the Colossus of Rhodes and Lighthouse of Alexandria) — nothing whatever survives.
According to the 2001 census, Greece had a population of 10,964,020. Of those, 58.8% lived in urban areas, whereas only 28.4% lived in rural areas. The population of the two largest cities in Greece, Athens and Thessaloniki, reached almost 4 million. Although the population of Greece continues to grow, Greece faces a serious demographic problem: for the first time in 2002 the number of deaths surpassed the number of births.
Greek folk traditions are said to derive from the music played by ancient Greeks. There are said to be two musical movements in Greek folk music: akritic and klephtic. Akritic music comes from the 9th century akrites, or border guards of the Byzantine Empire. Following the end of the Byzantine period, klephtic music arose before the Greek Revolution, developed among the kleftes, warriors who fought against the Ottoman Empire. Klephtic music is monophonic and uses no harmonic accompaniment.
Man himself and the animals had come into being by like transmutations. Mankind was supposed by Anaximander to have sprung from some other species of animals, probably aquatic. For this, even though he had no theory of natural selection, some people consider him to be evolutionary theory's most ancient proponent.
Whether or not we attribute the Pythagorean theorem to Pythagoras, it seems fairly certain that he had the pioneering insight into the numerical ratios which determine the musical scale, since this plays a key role in many other areas of the Pythagorean tradition and since no evidence remains of earlier Greek or Egyptian musical theories. Another important discovery of this school -- which upset Greek mathematics, as well as the Pythagoreans' own belief that whole numbers and their ratios could account for geometrical properties -- was the incommensurability of the diagonal of a square with its side. This result showed the existence of irrational numbers.
In the 1950s and 1960s Greece continued to develop slowly, initially with the help of the U.S.A Marshall programme and later with the growth of tourism. In 1967 the military seized power in a coup d'état, overthrew the social-democrat government of George Papandreou, senior and established what became known as the Régime of the Colonels, supported by the U.S.A. In 1973 the régime abolished the Greek monarchy. In 1974, dictator Papadopoulos denied help to the USA and as a result the (US/Kissinger) "appointed" a new dictator named Ioannides. Many hold Ioannides responsible for the coup against President Makarios of Cyprus -- the coup seen as the pretext for the first wave of the Turkish invasion of Cyprus in 1974. The Cyprus events and the outcry following a bloody suppression of Athens Polytechnic uprising in Athens led to the implosion of the military régime. A charismatic exiled politician, Konstantinos Karamanlis, returned from Paris as interim prime minister and later gained re-election for two further terms at the head of the conservative Nea Dimokratia party. In 1975, following a referendum to confirm the deposition of King Constantine II, a democratic republican constitution came into force. Another previously exiled politician, Andreas Papandreou also returned and founded the socialist PASOK party, which won the elections in 1981 and dominated the country's political course for almost two decades.
The majority of Greeks (95 to 98%) have at least nominal membership of the Eastern Orthodox Church, although religious observance has declined in recent years. Greek Muslims make up about 1.3% of the population, and live mainly in Thrace. Greece has some Roman Catholics: mainly in the Cyclades islands of Syros, Paros and Naxos; some Protestants and some Jews, mainly in Thessaloniki. Some groups in Greece have started an attempt to reconstruct Hellęnismos, the old Greek pagan religion. See also: Greek Orthodox Church.
Historically, Greece has been a net beneficiary of the EU budget. Net payments to Greece totaled $4.9 billion in 1998, representing 4.2% of GDP. Net inflows were estimated at about $5 billion in 1998. These funds contribute significantly to Greece's current accounts balance and reduce the state budget deficit.
The Greek media, collectively, is a very influential institution — usually aggressive, sensationalist, and frequently irresponsible with regard to content. Most of the media are owned by businessmen with extensive commercial interests in other sectors of the economy. They use their newspapers, magazines, and radio and TV channels to promote their commercial enterprises as well as to seek political influence.
