A noble man who took part in the assassination
of Constans II in Syracuse, Mezezius was proclaimed emperor by the army
in the later part of 668. The news of Constans II assassination did
not reach Constantinople until November or December, where pressure as
placed on the exarch of Syracuse to proclim Constantine IV, son of Constans
II as emperor. At that time Mezezius was deposed and exiled.
The coinage was thought of be irregular products of Constantine IV until
the last decade where Mezezius took his rightful place in history.
The reference numbers for Dunbarton Oaks and Hahn are for those of Constantine
IV.
