Like most Indo-Greek rulers, Strato I Soter Dikaios ("savior" and "the just") is unknown to history apart from his coins, which suggest his rule encompassed Gandhara and the Punjab. His earliest coins show a youthful bust cojoined with that of a woman named Agathokleia, possibly his mother, who may have ruled as regent during his minority (see previous lot). His solo portraits show a somewhat older visage, eventually acquiring a beard (although a new theory posits that the bearded portrait depicts a different king of the same name, possibly Agathokleia's brother). Athena appears in several poses on the reverses of his coins, here in the traditional stance of Athena Alkidemos, preparing to hurl a thunderbolt.
