According to Lorton, in the Papyrus Bremner-Rhind 28, 20–24, in a document called 'Book of Overthrowing Apophis', there is a poem narrating how the sun god Ra had created the god Shu and goddess Tefnut by fellating himself and spitting out his own semen onto the ground. Egyptologist David Lorton says that many ancient texts refer to autofellatio within the religion of Egypt, both in the realm of the gods and among the followers performing religious rituals.
