On some of his silver coins Hermaeus is associated with his queen, Calliope, who, like Agathocleia, must have been a princess in her own right. In the *obv.* type which represents the jugate busts of the king and queen, both of them wear the diadem; and their names are associated in the Greek and Kharoshṭhī legends. These joint coins are distinguished from the other issues of Hermaeus by the *rev.* type ‘King on prancing horse’; and, as this type is characteristic of Antimachus and his successors, it is probable, as Cunningham suggested, that Calliope was a princess of this family (p. 546 f., and *Summary*, pp. 586).
