Most documents that mention king Khufu were written by ancient Egyptian and Greek historians around 300 BC. Khufu's obituary is presented there in a conflicting way: while the king enjoyed a long-lasting cultural heritage preservation during the period of the Old Kingdom and the New Kingdom, the ancient historians Manetho, Diodorus and Herodotus hand down a very negative depiction of Khufu's character. Thanks to these documents, an obscure and critical picture of Khufu's personality persists.
