"Trajan was, in fact, quite active in Egypt. Separate scenes of Domitian and Trajan making offerings to the gods appear on reliefs on the propylon of the Temple of Hathor at Dendera. There are cartouches of Domitian and Trajan on the column shafts of the Temple of Knum at Esna, and on the exterior a frieze text mentions Domitian, Trajan, and Hadrian" Stadter, Philip A.; Stockt, L.
