DELMATIUS (Flavius Julius) or Dalmatius, for the name is spelt in both ways on coins and by authors, was the son of Dematius, brother of Constantine the Great, who was elevated to the office of Caeser. He was born at Toulouse, or, as some say, Arles. His mother 's name is unknown. Being a favorite with his uncle Constantine, whom he resembled in character, he was elected Consul u. c. 1086 (A.D. 333) and two years afterwards (335) was created Caeser. Whilst yet is a private capacity, he defeated Calaocerus, who revolted in Cyprus, and brought him prisoner to his uncle, who consigned him to the flames. In the memorable partition of the empire, which Constantine made in the latter year, Delmatius received as his share Thrace, Macedonia and Achaia ; but shortly after the decease of Constantine. he was put to death by the soldiers, A.D. 337, under the pretence of desiring to be governed only by the children of Constantine; and this was done with the connivance of Constantius II. who was envious of him.
On his coins, which are rare even in brass and of the highest rarity in gold and silver, he is styled DELMATIVS CAESAR--DEMATIVS NOB (ILISSIMVS) CAESAR--and FL IVL. DELMATIVS (or DALMATIVS) NOB C.
