Ammon, a deity extensively worshipped in ancient times in many countries of Africa and Europe. The Egyptians called him Amen or Amen-Ra (Amnion the Sun), the Hebrews Amon, the Greeks Zeus Ammon, and the Romans Jupiter Ammon. His most celebrated temples were at Thebes in Upper Egypt, in the Libyan oasis of Ammonium (now Siwah), and at Dodona in Greece. He was generally represented in the form of a ram, or as a human being with the head of a ram. This representation meant probably that Ammon stood in the same relation to men as the ram does to the flock; that he was the guide, governor, and protector of the people. The derivations of the name Amen are numerous, but none has as yet obtained general acceptance.
