An Egyptian priest and annalist; born at Sebennytus, in Lower Egypt; lived about 250 B. C. He composed three books in Greek, which purported to give the history of Egypt from the mythical period downward; but only fragments remain, imbedded in the works of Josephus and other writers. His writings, coming down through translations and transliterations of Syncellus, Eusebius, Jerome, and Africanus, have been the chief source of information as to the successive dynasties of Egypt; and with the inscriptions coming to light, assist archaeologists in framing its chronology.
