The track from Iôlkos to Kolchis, however, though plausible as far as it went, did not realize all the conditions of the genuine fabulous voyage: it did not explain the evidences of the visit of these maritime heroes which were to be found in Libya, in Krêtê in Anaphê, in Korkyra, in the Adriatic Gulf, in Italy and in Æthalia. It became necessary to devise another route for them in their return, and the Hesiodic narrative was (as I have before observed), that they came back by the circumfluous ocean; first going up the river Phasis into the circumfluous ocean; following that deep and gentle stream until they entered the Nile, and came down its course to the coast of Libya. This seems also to have been the belief of Hekatæus.[611] But presently several Greeks (and Herodotus among them) began to discard the idea of a circumfluous ocean-stream, which had pervaded their old geographical and astronomical fables, and which explained the supposed easy communication between one extremity of the earth and another. Another idea was then started for the returning voyage of the Argonauts. It was supposed that the river Ister, or Danube, flowing from the Rhipæan mountains in the north-west of Europe, divided itself into two branches, one of which fell into the Euxine Sea, and the other into the Adriatic. [611] See above, p. 239. There is an opinion cited from Hekatæus in Schol. Apoll. Rhod. iv. 284. contrary to this, which is given by the same scholiast on iv. 259. But, in spite of the remarks of Klausen (ad. Fragment. Hekatæi, 187. p. 98), I think that the Schol. ad. iv. 284 has made a mistake in citing Hekatæus; the more so as the scholiast, as printed from the Codex Parisinus, cites the same opinion without mentioning Hekatæus. According to the old Homeric idea, the ocean stream flowed all round the earth, and was the source of all the principal rivers which flowed into the great internal sea, or Mediterranean (see Hekatæus, Fr. 349; Klausen, ap. Arrian. ii. 16, where he speaks of the Mediterranean as the μεγάλη θάλασσα). Retaining this old idea of the ocean-stream, Hekatæus would naturally believe that the Phasis joined it: nor can I agree with Klausen (ad Fr. 187) that this implies a degree of ignorance too gross to impute to him.
