ZOSIMUS, an ancient historian who lived at the end of the fourth and beginning of the fifth centuries. There are six books of his history extant; in the first of which he runs over the Roman affairs in a very succinct manner from Augustus to Diocletian; the other five are written more diffusively. Zosimus was a zealous Pagan; whence we find him frequently inveighing with great bitterness against the Christian princes, particularly against Constantine the Great, and the elder Theodosius. His history has been published with the Latin version of Leunclavius at Frankfurt, 1590, with the other minor historians of Rome, in folio; and at Oxford in 8vo. 1679.
