Cainan (sometimes the name is spelled Kainam) was the son of Arpachsad: "And the son grew, and his father taught him writing, and he went to seek for himself a place where he might seize for himself a city. And he found a writing, which former generations had carved on the rock, and he read what was thereon, and he transcribed it and sinned owing to it, for it contained the teaching of the Watchers in accordance with which they used to observe the omens of the sun, moon and stars in all the signs of heaven." Here, then, is the origin of the star worship of the Sabians traced all the way back to the mysterious Watchers--whoever they were, whatever they are--who settled in the Near East in antediluvian times, taught our ancestors forbidden knowledge, broke some fundamental commandment by mating with human women and, as a result, were remembered as being responsbile for the great global cataclysm of the Deluge.
