Peripatetic school

The Peripatetic school was a school of philosophy in Ancient Greece. Its teachings derived from its founder, Aristotle (384–322 BC), and peripatetic is an adjective ascribed to his followers.

The school dates from around 335 BC when Aristotle began teaching in the Lyceum. It was an informal institution whose members conducted philosophical and scientific inquiries. After the middle of the 3rd century BC, the school fell into a decline, and it was not until the Roman era that there was a revival. Later members of the school concentrated on preserving and commenting on Aristotle's works rather than extending them; it died out in the 3rd century.

The study of Aristotle's works continued by scholars who were called Peripatetics through Late Antiquity, the Middle Ages, and the Renaissance. After the fall of the Western Roman Empire, the works of the Peripatetic school were lost to the Latin West, but they were preserved in Byzantium and also incorporated into early Islamic philosophy. Western Europe recovered Aristotelianism from Byzantium and from Islamic sources in the Middle Ages.
