While the unknown author is considered to have displayed a thorough knowledge of Manethon, the best indication of forgery is the introductory dedication to Ptolemy II Philadelphus, referring to him as "σεβαστῷ" ("sebastōi") — i.e. "august" or "Augustus", a Roman title that was not used until centuries after Manethon's death.
