A literary masterpiece from the 13th dynasty talking about Khufu is the famous Papyrus Westcar, where king Khufu witnesses a magical wonder and receives a prophecy from a magician named Dedi. Within the story, Khufu is characterised in a difficult-to-assess way. On one hand, he is depicted as ruthless when deciding to have a condemned prisoner decapitated to test the alleged magical powers of Dedi. On the other hand, Khufu is depicted as inquisitive, reasonable and generous: He accepts Dedi's outrage and his subsequent alternative offer for the prisoner, questions the circumstances and contents of Dedi's prophecy and rewards the magician generously after all. The contradictory depiction of Khufu is the object of great dispute between Egyptologists and historians to this day. Especially earlier Egyptologists and historians such as Adolf Erman, Kurt Heinrich Sethe and Wolfgang Helck evaluated Khufu's character as heartless and sacrilegious. They leaned on the ancient Greek traditions of Herodotus and Diodorus Siculus, who described an exaggerated negative character image of Khufu, ignoring the paradoxical (because positive) traditions the Egyptians themselves had always taught.
