The son of Adam. Concerning him it is said: "And the sons of God went in to the daughters of mankind" (that is, the daughters of Cain).[1] For the men of that time called Seth a god because he had invented the Hebrew letters and the names of the stars.[2] Besides, they admired his great piety. He was the first to be surnamed and called a god, just as the Lord also says to Moses: "I have given you as a god to Pharaoh."[3] And concerning the virtuous and spiritual men and the judges he said: "You shall not revile the gods, and you shall not speak evil of the leader of your people."[4] With reason therefore the children of Seth and Enos and Enoch were considered sons of God or sons of the gods according to Symmachus. Overcome by licentiousness they went in to the daughters of Cain. From these unlawful unions the giants were born. Because of the just [ancestor] they were strong and tall, but because of the unjust and impure [ancestor] they were wicked and extremely evil.[5]
