Isis the daughter of Hermes

“Moreover, many writers have held her to be the daughter of Hermes,9 and many others the daughter of Prometheus, because of the belief that Prometheus is the discoverer of wisdom and forethought, and Hermes the inventor of grammar and music. For this reason they call the first of the Muses at Hermopolis Isis as well as Justice: for she is wise, as I have said, and discloses the divine mysteries to those who truly and justly have the name of ‘bearers of the sacred vessels’ and ‘wearers of the sacred robes.’” – Plutarch, On Isis and Osiris 352b
