It must be remembered that we still possess well-executed hieroglyphic inscriptions dating from the time of Decius, 250 years after Christ. Thus the Egyptian commentator on Greek poetry could hardly have needed a translator, whereas the Hieroglyphica seems to have been first rendered into Greek by Philippus. The combination by which the author called in Egyptian Horus (the son of Isis) is supposed to have been born in Philae, where the cultus of the Egyptian heathen was longest practised, and where some familiarity with hieroglyphics must have been preserved to a late date, takes into due account the real state of affairs at the period I have selected for my story.
