whose full name was FLAVIUS VALERIUS LICINIANUS LICINIUS, was a son of the emperor Licinius and Constantia [CONSTANTIA ; THEODORA], and was born A. D. 315. On the first of March 317, when not yet twenty months old, he was proclaimed Caesar along with his cousins Crispus and Constantinus, and in 319 was the colleague in the consulship of his uncle Constantine the Great. But the poor boy was stripped of all his honours upon the downfal of his father in 323, and, according to Eutropius, whose account is corroborated by St. Jerome, was put to death in 323, at the same time with the ill-fated Crispus [CRISPUS]. It appears from medals that he enjoyed the haughty titles of Jovius and Dominus in common with his father; but although coins have been described on which he appears with the epithet Augustus we have no reason to believe that he had any formal claim to this designation, which was probably annexed to his name by moneyers in ignorance or flattery.
