In late Greek mythology as developed in Ptolemaic Alexandria, Harpocrates is the god of silence, adapted from the Egyptian child god Horus. To the ancient Egyptians, Horus represented the new-born Sun, rising each day at dawn. When the Greeks conquered Egypt under Alexander the Great, they transformed the Egyptian Horus into their Hellenistic god known as Harpocrates, a rendering from Egyptian Har-pa-khered or Heru-pa-khered (meaning "Har, the Child"). Horus was conceived by Isis, the mother goddess, from Osiris, the original god-king of Egypt, who had been murdered by his brother Set. Among the Egyptians the full-grown Horus was considered the victorious god of the Sun who each day overcomes darkness. In this way Harpocrates, the child Horus, personifies the newborn sun each day, the first strength of the winter sun, and also the image of early vegetation. Egyptian statues represent the child Horus, pictured as a naked boy with his finger on his mouth, a realization of the hieroglyph for "child" , or with the mother Isis.
