82 HERODOTUS. [CHAP. to the other two combined, and much broader than they were *" Though he was well aware that the Arabian Tnlf i Boundaries * i , vjuii between them, was a long and narrow sea to the eastward of Africa, he maintained that the western frontier of Egypt formed the true boundary of that continent on the side towards Asia1. He admits that the Nile was the limit usually accepted by the Greeks, but objects to it on the ground that on this supposition Egypt, through which that river fl0wS) would be partly in Asia and partly in Libya. Again, whilc he men- tions the view that the Cimmerian Bosporus and the Tanais were to be regarded as dividing Asia from Europe, he himself would draw the line at the Phasis, the Caspian Sea, and the Araxes, in a direction running due east3, ' The mention of the last-named river introduces one of the most puzzling questions ^Hisconfu- of Herodotean geography. ^He seems indeed to sion about the have confused together two streams called Araxes— one the modem Aras, which discharges its waters into the western side of the Caspian, for he says that the Araxes rose in the land of the Matieni, i.e. ia tjjC nQT^ of Armenia, where the sources of the Aras lie ; the other— which Cyrus had to cross in order to attack the Massagetae and which is described as a great river, not much inferior to the Danube— the Jaxartes, which flows into the sea of Aral- but as that piece of water was unknown to the ancients it is not surprising that Herodotus represents it as reaching the Caspian3. But the difficulty does not end here, for £ his description of the boundary line between Europe and Asia he says definitely that the Araxes, which lies beyond the Caspian flows towards the rising sun4; that is to say, in a direction exactly opposite to the course of the Jaxartes, and away from the Caspian. Unless we accept Canon Rawlinson's somewhat drastic suggestion that the writer here made a lapsus and described the river as running east, when he meaat to say that it ran west, the confusion appears to be inextricable In his account of the geography of Asia Herodotus introduces . 4. 40 ; 6 Apdftj jrora/ify ftw vpbs iJAiov di^ovra.
