Roman rebel
Flavius Marcianus (Greek: Μαρκιανός, fl. AD 469–484) was a member of the Leonid dynasty. The son of the Western emperor Anthemius, Marcianus married Leontia, the daughter of the Eastern Roman emperor Leo I. He was consul twice, and in 479 unsuccessfully attempted to overthrow the emperor Zeno. After his capture he was forced to become a monk; he escaped and raised an army but was defeated and recaptured by Flavius Appalius Illus Trocundes. In 484, when the Isaurian general Illus revolted against Zeno, Marcianus was freed and Illus proclaimed him emperor, before deposing him in favour of Leontius.
