In the Byzantine period, religious art was the dominate theme, with highly-decorated mosaics and icons adorning religious buildings. The Renaissance artist, El Greco (Domenikos Theotocopoulos), responded to Byzantine and 16th century Mannerist art, producing sculpture and paintings with a liberated form, light and colour that inspired 20th century artists such as Pablo Picasso and Jackson Pollock
Funeral statuary evolved during this period from the rigid and impersonal kouros of the Archaic period to the highly personal family groups of the Classical period. These monuments are commonly found in the suburbs of Athens, which in ancient times were cemeteries on the outskirts of the city. Although some of them depict "ideal" types — the mourning mother, the dutiful son — they increasingly depicted real people, typically showing the departed talking his dignified leave from his family. They are among the most intimate and affecting remains of the Ancient Greeks.
There is also a question relating to the word "art" in Ancient Greece. The Ancient Greek word te??? tekhnê, which is commonly translated as "art," more accurately means "skill" or "craftsmanship" (the English word "technique" derives from it). Greek painters and sculptors were craftsmen who learned their trade as apprentices, often being apprenticed to their fathers, and who were then hired by wealthy patrons. Although some became well-known and much admired, they were not in the same social position as poets or dramatists. It was not until the Hellenistic period (after about 320 BC) that "the artist" as a social category began to be recognised
About 80% of Greece is mountainous or hilly. Much of the country is dry and rocky; only 28% of the land is arable. Greece has mild, wet winters and hot, dry summers. Temperatures are rarely extreme, although snowfalls do occur in the mountains and occasionally even in Athens in the winter.
Their works, although connected in many fundamental ways, differ considerably in both style and substance. Plato wrote several dozen philosophical dialogues—arguments in the form of conversations, usually with Socrates as a participant—and a few letters. Though the early dialogues deal mainly with methods of acquiring knowledge, and most of the last ones with justice and practical ethics, his most famous works expressed a synoptic view of ethics, metaphysics, reason, knowledge, and human life. Predominant ideas include the notion that knowledge gained through the senses always remains confused and impure, and that the contemplative soul that turns away from the world can acquire "true" knowledge. The soul alone can have knowledge of the Forms, the real essences of things, of which the world we see is but an imperfect copy. Such knowledge has ethical as well as scientific import. One can view Plato, with qualification, as an idealist and a rationalist.
In the 19th century, opera composers like Nikolaos Mantzaros (1795 - 1872), Spyridion Xyndas (1812 - 1896) and Spyros Samaras (1861 - 1917) helped revitalize Greek classical music
The transition from the Classical to the Hellenistic period occurred during the 4th century. Following the conquests of Alexander the Great (336 BC to 323 BC), Greek culture spread across the known world as far as India. Thus it became more diverse and more influenced by the cultures of the peoples drawn into the Greek orbit. In the view of most art historians, it also declined in quality and originality; this, however, is a subjective judgement which artists and art-lovers of the time would not have shared. New centres of Greek culture, particularly in sculpture, developed in Alexandria, Antioch, Pergamum, and other cities. By the 2nd century the rising power of Rome had also absorbed much of the Greek tradition — and an increasing proportion of its products as well.
During this period sculpture became more and more naturalistic. Common people, women, children, animals and domestic scenes became acceptable subjects for sculpture, which was commissioned by wealthy families for the adornment of their homes and gardens. Realistic portraits of men and women of all ages were produced, and sculptors no longer felt obliged to depict people as ideals of beauty or physical perfection. At the same time, the new Hellenistic cities springing up all over Egypt, Syria, and Anatolia required statues depicting the gods and heroes of Greece for their temples and public places. This made sculpture, like pottery, an industry, with the consequent standardisation and some lowering of quality. For these reasons many more Hellenistic statues have survived than is the case with the Classical period.
The oldest surviving folk songs in all of Greece can be traced to the 17th century, when songs in the rizitika type were recorded by monks at Iviron and Xyropotamos at Mount Athos. Recording secular folk songs was almost certainly forbidden by the monk's code of conduct. However, the connection between music and religion continues in modern Crete; priests are said to be excellent folk singers, including the rizitiko singer Aggelos Psilakis. It was during this period, when modern Cretan folk music was formed, that Francisco Leontaritis was active. Leontaritis is said to be the father of modern Greek music.
Thales' most famous belief was his cosmological doctrine, which held that the world originated from water. Aristotle considered this belief roughly equivalent to the later ideas of Anaximenes, who held that everything in the world was composed of air. Thus it is sometimes assumed that Thales considered everything to be made from water. According to Lloyd, however, it's likely that while Thales saw water as an origin, he never pondered whether water continued to be the substance of the world.
