Ptolemy the Geographer, (second century C.E.), Alexandrian astronomer and geograher. Among his many works was a "Geography" in eight books in which he fixed the longitude and latitude of thousands of places, including many in Palestine: Ptolemais (Acre), Sycaminon (Haifa), Mount Carmel, Caesarea Stratonis (Caesarea), Iope (Jaffa), Ascalon (Askelon), Tiberias, Neapolis (Nablus), Gaza, Lydda, Hierosolyma (Jerusalem). However, Ptolemy's locations are often in error.
