Jean Auguste Dominique Ingres, Jupiter and Thetis, 1811, oil on canvas, 324 x 260 cm, Musée Granet, Aix-en-Provence
Zeus (Greek) or Jupiter (Roman) is the king of the gods and the lord of the heavens. His father was Kronos/Saturn, an ancient god who ate all his other children. Raised by nymphs on Mount Ida, he eventually defeated his father, saved his siblings, and took control of the universe. He married his sister Hera/Juno, but had many affairs with both mortal women and goddesses (oftentimes in disguise) and fathered many children, including the gods Aphrodite/Venus, Apollo, Ares/Mars, Artemis/Diana, Athena/Minerva, Dionysus/Bacchus, Hermes/Mercury, and Hephaestus/Vulcan, as well as the mortals Helen of Troy, Hercules, and Perseus. His siblings include Demeter/Ceres, Hades/Pluto, Hestia/Vesta, and Poseidon/Neptune.
He is also frequently seen with a lightning bolt, and sometimes in a manner of disguises, including a bull or a swan.
