In which year did Plato's "Academy" get closed?(I need exact date if possible)?

Answer 1

"The emperor Justinian closed the school in AD 529, a date that is often cited as the end of Antiquity. According to the sole witness, the historian Agathias, its remaining members looked for protection under the rule of Sassanid king Khosrau I in his capital at Ctesiphon, carrying with them precious scrolls of literature and philosophy, and to a lesser degree of science. After a peace treaty between the Persian and the Byzantine empire in 532 guaranteed their personal security (an early document in the history of freedom of religion), some members found sanctuary in the pagan stronghold of Harran, near Edessa. One of the last leading figures of this group was Simplicius, a pupil of Damascius, the last head of the Athenian school. The students of the Academy-in-exile, an authentic and important Neoplatonic school surviving at least until the 10th century, contributed to the Islamic preservation of Greek science and medicine, when Islamic forces took the area in the 7th century (Thiele)."

Answer 2

You can try to use Plato's death date, although he probably had a disciple or two who tried to carry on after Plato's death. Also, that answer is a bit simplistic. Eras, like the Romantic Era or the Victorian Era, don't begin on Aug. 11 1850 and end on whatever. And to a certain extent, the ame can be said of Plato's academy. Don't think of it as a school building that was closed and the doors padlocked from the outside. Think more interms of a second school of thought displacing Platonism. But strains of Platonic thought invade our thinking today -- in governmanet, in education, in religion even. So if you want to get tricky about the whole issue, it's not closed as long as there are questioning minds and believers in a realm of absolutes that we but see the shadows of on the wall of a cave.
