Agathias a Byzantine historian, was born at Myrina, in AEolis, about 536 or 537 A.D. He resided at Alexandria, and after 554 at Constantinople, where he practiced law, but whether he was a Christian or a heathen is uncertain. He died between 582 and 594. He wrote a valuable history of the eastern Roman empire, from 553 to 559, which was published in Greek by Vulcanus at Leyden (1594). The best edition is that of Niebuhr, in the Corpus Script. Byzant.
