Constantinius II (A.D. 337-362)
A.D. 348 to 363. First came into use by Constantinus II and used by Constans, Constantine Gallus, Magnetius and Julian II who ruled until 363 AD. Falling Horseman and all other FEL TEMP REPARATIO types began with the coinage reform of 348 that took place when the only emperors alive were Constans and Constantius II. Constantine I and II had both died. After Constans died, Constantius II appointed Constantius Gallus as Caesar and soon replaced him with Julian II so both of them also had the type. Shortly before he died, Constantius II ended the type in favor of his new one showing the emperor standing with legend SPES REPVBLICE.
