Book excerpt: Tutu (Tithoes) was a popular god in the Ptolemaic and Roman periods of Egyptian history, with his origins in the earlier Egyptian religious tradition. The god provided protection against demons, and his appearance as a striding sphinx was often combined with symbols of his power and visual references to demons and other divinities. The god Tutu demonstrates the continuing vitality of the pharaonic religion under the pressure of foreign cultures and ideas. This monograph provides the first comprehensive study of the god Tutu. It is based upon a collection of attestations, largely unpublished, which derive from monuments in various parts of Egypt and from museum collections all over the world. Moreover, the results of recent archaeological field work in Shenhur and in the temple of Tutu in the Dakhla Oasis have been included in full. The catalogue of monuments is accompanied by an analysis of the god Tutu, his iconography and his place in the Egyptian religion.
