Aristotle was born at Stageira, in the dominion of the kings of Macedonia, in 384 BC. For twenty years he studied at Athens in the Academy of Plato, on whose death in 347 he left, and, some time later, became tutor of the young Alexander the Great. When Alexander succeeded to the throne of Macedonia in 335, Aristotle returned to Athens and established his school and research institute, the Lyceum, to which his great erudition attracted a large number of scholars. After Alexander's death in 323, anti-Macedonian feeling drove Aristotle out of Athens, and he fled to Chalcis in Euboea, where he died in 322. His writings, which were of extraordinary range, profoundly affected the whole course of ancient and medieval philosophy, and they are still eagerly studied and debated by philosophers today. Very many of them have survived and among the most famous are the Ethics and the Politics. Quintus Horatius Flaccus was born in 6 B.C. at Venusia in Apulia. His father, though once a slave, had made enough money as an auctioneer to send his son to a well-known school in Rome and subsequently to university in Athens. There Horace joined Brutus' army and served on his staff until the defeat at Philippi in 42 BC. On returning to Rome, he found that his father was dead and his property had been confiscated, but he succeeded in obtaining a secretarial post in the treasury, which gave him enough to live on. The poetry he wrote in the next few years impressed Virgil, who introduced him to the great patron Maecenas in 38 BC. This event marked the beginning of a life-long friendship. From now on Horace had no financial worries; he moved freely among the leading poets and statesmen of Rome; his work was admired by Augustus, and indeed after Virgil's death in 19 BC he was virtually Poet Laureate. Horace died in 8 BC, only a few months after Maecenas.
