Aelian
Among the Aigyptians Apis is believed to be the god whose presence is most manifest. He is born of a cow on which a flash of light from heaven has fallen and caused his engendering. The Greeks call him Epaphos and trace his descent from his mother the Argive Io, daughter of Inakhos. The Aigyptians however reject the story as false, and appeal to time as their witness, for they maintain that Epaphos was born late down the ages, whereas the first Apis visited mankind many, many thousands of years earlier. — 11.10
