Jupiter Optimus Maximus Helipolitanus: Latin name of the supreme god venerated in the great temple of Baalbek.
According to the Roman author Macrobius, the cult statue in Baalbek had been taken from Egypt, was made of gold, and showed the god as a beardless, young man, "with its right hand raised and holding a whip, like a charioteer," while the left hand held "a lightning bolt, and ears of grain" (Macrobius, Saturnalia, 1.23.12).
We also know that the statue was flanked by two bulls (Hadad's animal), and that the god wore representations of the Sun and Moon on his breast. On his head, he wore a basket-shaped hat, a kalathos. With so many names and attributes, it is fitting that the god of Heliopolis also embodied several qualities: fertility god, lord of thunder and rain, oracular god, supreme deity. He was also a sun god, which may or may not explain the orientation of the temple, more or less on the east.
Macrobius informs us that during a session of the oracle, the statue was placed in a litter; the bearers sort of sensed the divine will and carried it in certain directions, which could be "decoded" by the priests (Saturnalia, 1.23.13). A similar practice is known from the oracle of Ammon in Siwa in Egypt.
