 It is impossible to say which of the two branches was regarded by the ancients as the true Himera; but in either case that river has a course of above from north to south, and its sources are not more than from the north coast of the island.Hence Polybius and Livy's statement that the Himera nearly divides the whole of Sicily into two parts, is accurate.But it is evidently this circumstance, coupled with the fact that there was another river of the same name flowing into the Tyrrhenian Sea, which gave rise to the fable above noticed.
