Nikias, the Athenian, is said to have been so devoted to his art that he could think of nothing else: he would ask his servants if he had bathed or eaten, not being able to remember for himself. He was very rich, and when King Ptolemy of Egypt offered him more than sixty thousand dollars for his picture of Ulysses in the under-world, he refused this great sum, and gave the painting to his native city. Nikias seems to have greatly exalted and respected his art, for he contended that painters should not fritter away time and talent on insignificant subjects, but ought rather to choose some grand event, such as a battle or a sea-fight. His figures of women and his pictures of animals, especially those of dogs, were much praised. Some of his paintings were encaustic, that is to say, the colors were burned in; thus they must have been made on plaster or pottery of some sort. Nikias outlived Alexander the Great, and saw the beginning of the school of painters to which the great Apelles belonged--that which is called the Hellenic school, in which Greek art reached its highest point.
Apelles was the greatest of all Greek painters. He was born at Kolophon; but as he made his first studies at Ephesus he has been called an Ephesian: later he studied in the school of Sikyon, but even when a pupil there he was said to be the equal of all his instructors. Philip of Macedon heard of his fame, and persuaded Apelles to remove to his capital city, which was called Pella. While there Apelles became the friend of the young Alexander, and when the latter came to the throne he made Apelles his court-painter, and is said to have issued an edict forbidding all other artists from painting his portrait. Later on Apelles removed to Ephesus.
During the early part of his artistic life Apelles did little else than paint such pictures as exalted the fame of Philip, and afterward that of Alexander. He painted many portraits of both these great men; for one of Alexander he received nearly twenty-five thousand dollars; in it the monarch was represented as grasping the thunderbolt, as Jupiter might have done, and the hand appeared to be stretched out from the picture. This portrait was in the splendid temple of Diana, or Artemis, at Ephesus. Alexander was accustomed to say of it, "There are two Alexanders, one invincible, the living son of Philip--the other immutable, the picture of Apelles."
