2. FLAVIUS JULIUS DELMATIUS, who was educated at Narbonne under the care of the rhetorician Exsuperius; distinguished himself by suppressing the rebellion of Calocerus in Cyprus; was appointed consul A. D. 333; two years afterwards was created Caesar by his uncle, whom he is said to have resembled strongly in disposition; upon the division of the empire received Thrace, Macedonia, together with Achaia, as his portion; and was put to death by the soldiers in A. D. 337, sharing the fate of the brothers, nephews, and chief ministers of Constantine.
It must be observed that there is frequently great ditfficulty in distinguishing Delmatius the father from Delmatius the son. Many historians believe the former to have been the consul of A. D. 333, and the conqueror of Calocerus, the date of whose revolt is very uncertain.
A few coins of the younger in gold, silver, and small brass, are to to be found in all large collections, and on these his name is conjoined with the title of Caesar
and Princeps Juventutis,
the orthography being for the most part Delmatius,
also occasionally appears. (Auson. Prof.
