Epicurus (341–270 BC) was an ancient Greek philosopher and sage who founded a highly influential school of philosophy now called Epicureanism. He was born on the Greek island of Samos to Athenian parents. Influenced by Democritus, Aristotle, Pyrrho, and possibly the Cynics, he turned against the Platonism of his day and established his own school, known as "the Garden", in Athens. Epicurus and his followers were known for eating simple meals and discussing a wide range of philosophical subjects, and he openly allowed women to join the school as a matter of policy. An extremely prolific writer, he is said to have originally written over 300 works on various subjects, but the vast majority of these writings have been lost. Only three letters written by him—the Letters to Menoeceus, Pythocles, and Herodotus—and two collections of quotes—the Principle Doctrines and the Vatican Sayings—have survived intact, along with a few fragments and quotations of his other writings. Most knowledge of his teachings comes from later authors, particularly the Roman poet Lucretius, the biographer Diogenes Laërtius, the statesman Cicero, and the philosophers Philodemus and Sextus Empiricus.
