From
Αμμων (Ammon), the Greek form of Egyptian
Ymn (reconstructed as
Yamanu) which meant "the hidden one". In early Egyptian mythology he was a god of the air, creativity and fertility, who was particularly revered in Thebes. Later, during the Middle Kingdom, his attributes were combined with those of the god
Ra and he was worshipped as the supreme solar deity
Amon-Ra.
