Amun, reconstructed Egyptian Yam nu, was a deity in Egyptian mythology who in the form of Amun-Ra became the focus of the most complex system of theology in Ancient Egypt. Whilst remaining hypostatic deities, Amun represented the essential and hidden, whilst in Ra he represented revealed divinity. As the creator deity "par excellence", he was the champion of the poor and central to personal piety. Amun was self created, without mother and father, and during the New Kingdom he became the greatest expression of transcendental deity in Egyptian theology. He was not considered to be immanent within creation nor was creation seen as an extension of himself. Amun-Ra, likewise with the Hebrew creator deity, did not physically engender the universe. His position as King of gods developed to the point of virtual monotheism where other gods became manifestations of him. With Osiris, Amun-Ra is the most widely recorded of the Egyptian gods.
