(Ἡρωδιανός), a writer on Roman history. He was a Greek, though he appears to have lived for a considerable period in Rome, but without holding any public office. From his work, which is still extant, we gather that he was still living at an advanced age in the reign of Gordianus III., who ascended the throne A. D. 238. Beyond this we know nothing respecting his life.
