"This view of Egyptian religion played a central role in the two major ‘novels’ of the 2nd century AD, Heliodoros’ Aithiopika and Apuleius’ Metamorphoses or The Golden Ass. In his morally elevating and romantic story with a beautiful and virtuous Ethiopian – but not black – heroine, Heliodoros expressed great admiration for the Ethiopians and their gymnosophists (naked philosophers or gurus), but Aithiopika is focused on Egypt and the moral superiority of its religion. It also stresses the passionate interest taken in it by Greek priests, who saw it as the key to their own cults. When talking about the priests of Delphi bombarding a visiting Egyptian with questions, the author wrote: "In short, they forgot none of the interesting features of Egypt, for there is no country in the world which Greeks prefer to hear about.""
