ZOROASTER, as many say, was the same as the son of Noah named Ham. He was the first king of the Bactrians, and the first inventor of the arts of magic, and the seven liberal arts, and the courses of the sky and the stars. There are those who will report that he laughed as he was born. This should not be taken as a good omen; common people wail while being born. And so he was conquered by Ninus, and Ninus was also struck by an arrow; he died of this wound, leaving behind his son and heir, who was named Ninias. Ninus built the city of Nineveh, which took three days to walk around, and which Cyrus, King of the Assyrians, destroyed.
