Byzantine scholars at the Neoplatonic Academy fled to Persia after it was closed by Justinian. Later in the 8th Century, the Greaco-Arabic Translation Movement gathered books and translated original Greek texts into Arabic at the House of Wisdom (Grand Library of Baghdad). Study of hellenic philosophy restarted in the Arabic world until the Golden Age of Islamic Philosophy with Averroes whose commentarities reintroduced Hellenic philosophy to Europe in the 12th century.
