Toward the end of the Third Intermediate Period and the start of the Late Period, during the 25th and 26th Dynasties, the office was at its height both politically and economically. As the role of the high priests of Amun changed from a mostly spiritual to a more 'earthly' role, the Divine Adoratrice became the main focus of the cult of Amun in Thebes.
