Ennosigaeus

Graece enim fulmen κεραυνος ceraunos dicitur, et acra ακρα sumitas'; and a great many Greek and Hebrew words are given transliterated into Latin, ballein, fagein, Ennosigaeus.

Zeus, although he could claim supreme dominion under the law of primogeniture, was originally only a coequal ruler with his two brothers, Hades, king of the underworld, and Ennosigaeus, monarch of the salt sea-foam.
