391 CE
Quintus Aurelius Symmachus, urban prefect of Rome, pleads for traditional cult practices. He petitions Theodosius I to re-open the pagan temples, but is opposed by Ambrose. A Rouran chief named Heduohan (曷多汗) is defeated and killed in battle against the Tuoba Northern Wei Dynasty. Surviving Rouran move west towards the Gaoche, led by Heduohan's brother and successor, Shelun. Flames destroy the great Library of Alexandria, established in the Mouseion in the fourth century BC. Among the items lost in the fire are works of science, including parchments by the Greek astronomer Aristarchus of Samos asserting that the Earth orbits the Sun, and dozens of dramatic works by Euripides and Sophocles.
