Before the flood, the great sin that brought ruin on the human race was, that the "Sons of God" married others than the daughters of God,--in other words, those who were not spiritually their "sisters." (Gen 6:2,3) In the new world, while the influence of Noah prevailed, the opposite practice must have been strongly inculcated; for a "son of God" to marry any one but a daughter of God, or his own "sister" in the faith, must have been a misalliance and a disgrace. Hence, from a perversion of a spiritual idea, came, doubtless, the notion of the dignity and purity of the royal line being preserved the more intact through the marriage of royal brothers and sisters. This was the case in Peru (PRESCOTT), in India (HARDY), and in Egypt (WILKINSON). Hence the relation of Jupiter to Juno, who gloried that she was "soror et conjux"--"sister and wife"--of her husband. Hence the same relation between Isis and her husband Osiris, the former of whom is represented as "lamenting her brother Osiris." (BUNSEN) For the same reason, no doubt, was Rhea, made the sister of her husband Kronos, to show her divine dignity and equality. It is well known that Kronos, or Saturn, was Rhea's husband; but it is not so well known who was Kronos himself. Traced back to his original, that divinity is proved to have been the first king of Babylon. Theophilus of Antioch shows that Kronos in the east was worshipped under the names of Bel and Bal; and from Eusebius we learn that the first of the Assyrian kings, whose name was Belus, was also by the Assyrians called Kronos. As the genuine copies of Eusebius do not admit of any Belus, as an actual king of Assyria, prior to Ninus, king of the Babylonians, and distinct from him, that shows that Ninus, the first king of Babylon, was Kronos. But, further, we find that Kronos was king of the Cyclops, who were his brethren, and who derived that name from him, * and that the Cyclops were known as "the inventors of tower-building."
* The scholiast upon EURIPIDES, Orest, says that "the Cyclops were so called from Cyclops their king." By this scholiast the Cyclops are regarded as a Thracian nation, for the Thracians had localised the tradition, and applied it to themselves; but the following statement of the scholiast on the Prometheus of Aeschylus, shows that they stood in such a relation to Kronos as proves that he was their king: "The Cyclops...were the brethren of Kronos, the father of Jupiter."
The king of the Cyclops, "the inventors of tower-building," occupied a position exactly correspondent to that of Rhea, who "first erected (towers) in cities." If, therefore, Rhea, the wife of Kronos, was the goddess of fortifications, Kronos or Saturn, the husband of Rhea, that is, Ninus or Nimrod, the first king of Babylon, must have been Ala mahozin, "the god of fortifications." (see note below)
The name Kronos itself goes not a little to confirm the argument.
