Moreover the isthmus itself was not passable for ships, and Eratosthenes is unfortunate in his conjecture, for he considers that the strait at the Pillars was not then formed, so that the Atlantic should by that channel communicate with the Mediterranean, and that this sea being higher than the Isthmus [of Suez], covered it; but when the Strait [of Gibraltar] was formed, the sea subsided considerably; and left the land about Casium[229] and Pelusium[230] dry as far over as the Red Sea. But what account have we of the formation of this strait, supposing it were not in existence prior to the Trojan war? Is it likely that our poet would make Ulysses sail out through the Strait [of Gibraltar] into the Atlantic Ocean, as if that strait already existed, and at the same time describe Menelaus conducting his ships from Egypt to the Red Sea, as if it did not exist. Further, the poet introduces Proteus as saying to him, “Thee the gods Have destined to the blest Elysian Isles, Earth’s utmost boundaries.”[231] And what this place was, namely, some far western region, is evident from [the mention of] the Zephyr in connexion with it: “But Zephyr always gently from the sea Breathes on them.”[232] This, however, is very enigmatical. 32. But if our poet speaks of the Isthmus of Suez as ever having been the strait of confluence between the Mediterranean and the Red Seas, how much more credit may we attribute to his division of the Ethiopians into two portions, being thus separated by so grand a strait! And what commerce could he have carried on with the Ethiopians who dwelt by the shores of the exterior sea and the ocean? Telemachus and his companions admire the multitude of ornaments that were in the palace, “Of gold, electrum, silver, ivory.”[233] Now the Ethiopians are possessed of none of these productions in any abundance, excepting ivory, being for the most part a needy and nomad race. True, [you say,] but adjoining them is Arabia, and the whole country as far as India. One of these is distinguished above all other lands by the title of Felix,[234] and the other, though not dignified by that name, is both generally believed and also said to be pre-eminently Blessed.
