Jupiter or Jove. The sovereign divinity of the Romans from early times, with supreme power over gods and men. Originally a sky-god and responsible for the weather, he was particularly associated with rain and storms. His weapon was the thunderbolt. His temple, the center of the state cult, was on the Capitol at Rome and was shared with two other great Roman divinities, his wife Juno and daughter Minerva. He was identified with the Greek king of the gods, Zeus, and adopted Zeus' mythology as his own.

Juno. An ancient and important Italian goddess, the wife of Jupiter, and together with Jupiter and Minerva one of the three great deities of the Capitoline Triad. The goddess of marriage and, as Juno Lucina, of childbirth, Juno was early identified with the Greek Hera, adopting her characteristics and mythology. But Juno has one Roman myth, recounted by Ovid (Fasti 5.231-58). She was annoyed with Jupiter for producing Minerva from his own head without the need of a female, so the goddess Flora gave Juno a herb at whose touch she at once became pregnant. She gave birth to Mars, the Roman god of war. (In Greek myth, Hera is also the mother of the war-god, Ares. But his father is Zeus, the Greek equivalent of Jupiter; and the child that Hera bears without male assistance is Hephaestus, the god of fire.)
