Amun (Amun - Ra) mystery

Amun, reconstructed Egyptian Yamānu (also spelled Amon, Amoun, Amen, and rarely Imen, Greek Ἄμμων Ammon, and Ἅμμων Hammon), was the name of a deity in Egyptian mythology who gradually rose from being an abstract concept to the patron deity of Thebes and one of the most important deities in Ancient Egypt before fading into obscurity.-Wikipedia-
