HELIOPOLIS, (anc. geog.), ſo called by Herodotus and Diodorus Siculus, by Moſes On, and in Jeremiah Bethfemes; a city of Egypt, to the ſouth-eaſt of the Delta, and eaſt of Memphis; of a very old ſtanding, its origin terminating in fablc. Here ſtood the temple of the ſun, held in religious veneration. The city ſtood on an extraordinary mount, but in Strabo's time was deſolate. It gave name to the Nomos Heliopolites.—There was another Heliopolis in Cæſolyria, near the ſprings of the Orontes; ſo called from the worſhip of the ſun, which was in great vogue over all Syria.
