Over time, Egyptologists examined possible motives and reasons as to how Khufu's reputation changed over time. Closer examinations of and comparisons between contemporary documents, later documents and Greek and Coptic readings reveal that Khufu's reputation changed slowly, and that the positive views about the king still prevailed during the Greek and Ptolemaic era. Alan B. Lloyd, for example, points to documents and inscriptions from the 6th dynasty listing an important town called "Menat-Khufu", meaning "nurse of Khufu". This town was still held in high esteem during the Middle Kingdom period. Lloyd is convinced that such a heart-warming name wouldn't have been chosen to honour a king with a bad (or, at least, questionable) reputation. Furthermore, he points to the overwhelming number of places where mortuary cults for Khufu were practiced, even outside Giza. These mortuary cults were still practiced even in Saitic and Persian periods.
