Mut, whose name means “mother,” was the consort of Amun at Thebes.
Mut was an ancient Egyptian mother goddess whose identity and attributes changed over many centuries. Although she had earlier forms and associations outside Thebes, she became Amun’s principal consort as the Theban god rose to national prominence. Her name’s meaning makes the question’s clue especially direct, but it refers to the goddess’s role and name rather than to a single universal creation story.
At Karnak, Mut formed part of the Theban Triad with Amun and their son Khonsu. The triad gave Theban theology a family structure: Amun was the chief god, Mut the maternal and royal consort, and Khonsu the lunar or youthful son. Mut was commonly shown as a woman wearing the combined crown of Upper and Lower Egypt, emphasizing sovereignty over the united land.
Neith, Hathor, and Isis were also major goddesses with maternal, royal, or protective roles, which can make them tempting alternatives. Mut is nevertheless the canonical answer because her name explicitly means “mother” and her best-known Theban relationship is as Amun’s consort. The first securely documented depiction of the full Theban triad dates to Hatshepsut’s reign.
