Solidus - Heraclius, Heraclius Constantine and Heraclonas VICTORIA AVGU, Constantinopolis

Heraclonas was elevated to co-emperor in 638, likely at the insistence of his mother Martina, Heraclius's niece-wife — a union the Byzantine clergy had condemned as incestuous from the start. The three-figure solidus therefore dates to a narrow three-year window defined as much by dynastic maneuvering as by the catastrophic Arab conquests unfolding simultaneously in Syria and Egypt. Heraclius died in February 641 having lost Jerusalem, Antioch, and Alexandria within a decade of having personally recovered them from Persia.

Heraclonas's own reign lasted months before the Senate had his nose cut off and exiled him to Rhodes.
