During the Old Kingdom, Memphis became the capital of Ancient Egypt for more than eight consecutive dynasties. The city reached a peak of prestige under the Sixth Dynasty as a centre for the worship of Ptah, the god of creation and artworks. The alabaster sphinx that guards the Temple of Ptah serves as a memorial of the city's former power and prestige. The Memphis triad, consisting of the creator god Ptah, his consort Sekhmet, and their son Nefertem, formed the main focus of worship in the city.
