The Sistrum, as one of the insignia of Isis is seen in the hands of that deity, on coins of the Caecilia family; and on coins of Hadrian, the two Faustinas, Commodus, Claudius II Gothicus, Julian II ("The Apostate"), and other emperors. The same instrument is generally seen in the right hand of Egypt and Alexandria personified. "Isis (says Vaillant) was believed to be the genius of Egypt, who, by the shaking of the sistrum, signified the increase of the Nile." It also appears in the hand of Anubis, another of the monster-divinities of Egypt, on coins of Julian II and of Helena.
