Rulers in the late New Kingdom promoted a particularly important group of three gods above all others: Amun, Ra, and Ptah. These deities stood for the plurality of all gods, as well as for their own cult centers (the major cities of Thebes, Heliopolis, and Memphis) and for many threefold sets of concepts in Egyptian religious thought.
During the late New Kingdom period, prominent rulers elevated a distinctive trinity of gods to paramount importance: Amun, Ra, and Ptah. This pantheon embodied the diversity of all deities, as well as their respective cult centers (Thebes, Heliopolis, and Memphis) and various triple aspects in Egyptian theology.
