Zeús in Later Traditions
Roman religion identified Zeús directly with Iuppiter, importing his cult wholesale under the name Iuppiter Optimus Maximus; the equation was so natural that Greeks and Romans often treated them as one god with two names. In later antiquity Zeús-Iuppiter was syncretized with Semitic Baal and Egyptian Amun as a supreme sky deity, and the Hellenistic ruler cult made him the divine father of kings. Jupiter's planet and Tuesday (Germanic *Tīwaz's day) preserve his name's far-flung cognates, and the very words 'deus,' 'divine,' and 'day' descend from the same root family. The Christian God inherited much of Zeus's iconography — the enthroned father, the beard, the sky — without his mythology.
