About 8-10 years ago I was working on a writing project about Cleopatra. I remember one book talked about someone arranging for her temples/religious rites to keep going. Like basically the author's contention was that she was more closely linked to the priestly elite at Memphis than most people realize. They had the money, desire & connections to kind of keep her memory going. I'm trying to explain this Memphis thing to someone but I'm not doing it very well & I can't find that old notebook. I'd love to give her the name of the actual source. Any suggestions?
Off of the top of my head, Duane Roller's Cleopatra: A biography comes to mind. Roller is one of the main scholars who argued that Cleopatra, along with her father Ptolemy XII, was closely connected to the High Priest of Ptah in Memphis, and that within Egypt her memory was a lot more positive than it is in Graeco-Roman sources.
Roller also points out that the worship of Cleopatra (or the deified Cleopatra) in Egypt continued well into the Roman period, up until polytheism was supplanted by Christianity.
Roller's biography was published about 10 years ago, so that sounds like it could be a match.
