About Athens
Athens, the capital of Greece since 1834, was the leading intellectual centre of the classical Greek world. Socrates taught there, and four major philosophical schools took root in the city: Plato's Academy, founded around 387 BCE, Aristotle's Lyceum, the Stoa of Zeno, and Epicurus' Garden. Under Hellenistic and Roman rule Athens remained a place of study that drew students from across the empire; in the 4th century CE the Christian writers Basil of Caesarea and Gregory of Nazianzus studied there together, while Neoplatonist teachers kept lecturing. Emperor Justinian's ban on pagan teaching of philosophy in 529 is generally taken to mark the end of the city's ancient history.
