The Histories · 2.71

The river-horse is sacred in the district of Papremis, but for the other Egyptians he is not sacred; and this is the appearance which he presents: he is four-footed, cloven-hoofed like an ox, flat-nosed, with a mane like a horse and showing teeth like tusks, with a tail and voice like a horse, and in size as large as the largest ox; and his hide is so exceedingly thick that when it has been dried shafts of javelins are made of it.
