King Theodoric the Great raises the Frankish siege at Arles; the city is heroically defended by its inhabitants, assisted by the Ostrogothic general Theudis. The Ostrogoths overrun Provence (Southern Gaul), and consolidate their gains in the region.
Aryabhata, Indian astronomer and mathematician, comes up with concepts of mathematical equations, one of which explains the rotation of the Earth on its axis. This concept is far ahead of its time and he is fairly accurate in his description of it. He also comes up with a lot of other ideas about the Solar System, but many of them are flawed because he considers the Earth to be the center of the universe. Aryabhata is often given credit for coming up with the number zero and using it as a placeholder.
Revolt of Vitalian: Byzantine general Vitalian revolts against Emperor Anastasius I, and conquers a large part of the Diocese of Thrace. He gains the support of the local people, and assembles an army of 50,000–60,000 men.
Anastasius I reduces taxes in the provinces of Bithynia and Asia, to prevent them from joining the rebellion. Vitalian marches to Constantinople and encamps at the suburb of Hebdomon (modern Turkey).
Vitalian accepts an agreement and returns with his army to Lower Moesia. After a few inconclusive skirmishes, Anastasius I sends a Byzantine army (80,000 men) under his nephew Hypatius.
Vitalian defeats the Byzantines at Acris (Bulgaria), on the Black Sea coast. He attacks their fortified Laager in darkness, and in a crushing defeat kills a large part of the imperial army.
Vitalian, Byzantine general, marches again to Constantinople. A fleet of 200 vessels sails from the Black Sea ports and blockades the entrance of the harbor capital. Emperor Anastasius I is disquieted by riots in the city, which cost many casualties, and decides to negotiate with Vitalian.
Vitalian accepts the receipt of ransom money and gifts worth 5,000 pounds of gold for the release of Hypatius, a nephew of Anastasius I who has been a prisoner since the attack at Acris (see 513). Vitalian retreats back to Lower Moesia.
Marinus lands with an army on the shore of Sycae and defeats the rebels. Disheartened by the losses suffered, Vitalian flees north under cover of the night.[9]
July 9 – Emperor Anastasius I dies childless at Constantinople, age 88, after a 27-year reign in which he has abolished the sale of offices, reformed taxation, and perfected the empire's monetary system, but antagonized some with his heretical Monophysite religious policies. He is succeeded by Justin (Flavius Justinus), his comes excubitorum, commander of the palace guard. After his death, he leaves the imperial treasury richer by 23,000,000 solidi or 320,000 pounds of gold.[14]
August 28 – The end of Theodoric's tricennium, a thirty year statute of limitations after which unlawful seizures of land during his 489 invasion of Italy can no longer be contested.
