The Temple of Vesta (Rome)

Year 391 ( CCCXCI ) was a common year starting on Wednesday of the Julian calendar. At the time, it was known as the Year of the Consulship of Tatianus and Symmachus (or, less frequently, year 1144 Ab urbe condita ). The denomination 391 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Events

By place

Roman Empire

• Emperor Theodosius I establishes Christianity as the official state religion. All non-Christian temples in the Roman Empire are closed. The eternal fire in the Temple of Vesta at the Roman Forum is extinguished, and the Vestal Virgins are disbanded.
• 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.
• Saint Telemachus dies after being stoned to death. His date of death is also given to the year 404.

Asia

• 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.
• King Gwanggaeto the Great of Goguryeo (Korea) ascends to the throne. ^[1]

Literature

• 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.

Religion

• Patriarch Theophilus destroys all pagan temples in Alexandria under orders from Theodosius I. Christians go on an iconoclastic rampage, smashing religious symbols or monuments through the city and destroying the Temple of Serapis. The "Order of Monks" known as the Parabalani take charge of patrolling the streets.
