Jupiter or Jove, Zeus to the Greeks, was the king of the gods and god of the sky and thunder, and of laws and social order. As the patron deity of ancient Rome, he was the chief god of the Capitoline Triad, with his sister and wife Juno. The father of Mars, he is, therefore, the grandfather of Romulus and Remus, the legendary founders of Rome. Emperors frequently made vows to Jupiter for protection. The Roman's believed as the king of the gods, Jupiter favored emperors and kings, those in positions of authority similar to his own.
