As to Europe, however, it is clearly not known by any, either as regards the parts which are towards the rising sun or those towards the North, whether it be surrounded by sea: but in length it is known to stretch along by both the other divisions. And I am not able to understand for what reason it is that to the Earth, which is one, three different names are given derived from women, and why there were set as boundaries to divide it the river Nile of Egypt and the Phasis in Colchis (or as some say the Maiotian river Tanais and the Cimmerian ferry); nor can I learn who those persons were who made the boundaries, or for what reason they gave the names. Libya indeed is said by most of the Hellenes to have its name from Libya a woman of that country, and Asia from the wife of Prometheus: but this last name is claimed by the Lydians, who say that Asia has been called after Asias the son of Cotys the son of Manes, and not from Asia the wife of Prometheus; and from him too they say the Asian tribe in Sardis has its name.
