Following Alexander's conquest of Egypt, the cult of Isis spread across the Mediterranean, with its popularity reaching its zenith in the Roman period, when the "goddess of a thousand names" became one of the Mediterranean's principal deities. It is generally recognized that the iconography of Isis nursing Harpocrates influenced Christian representations of the Madonna and Child, particularly the Virgo lactans type popular in Medieval Europe.
