This is a fine little bronze issue struck in Antioch in modern day Syria under Flavius Delmatius, a Caesar of the Roman Empire and member of the Constantinian dynasty.
Delmatius was the nephew of Constantine I. His father, also named Flavius Delmatius, was the half-brother of Constantine and served as censor. He was the brother of Hannibalianus.
On 18 September 335, Delmatius the younger was raised to the rank of Caesar, with the control of Thracia, Achaea and Macedonia. He died in late summer 337, killed by his own soldiers. It is possible that his death was related to the purge that hit the imperial family at the death of Constantine, and organized by Constantius II with the aim of removing any possible claimant to imperial power other than the sons of the late emperor.
