“As when two adverse winds, blowing from Thrace, Boreas and Zephyrus.”[170] But Posidonius remarks that none of those who are really acquainted with these subjects, such as Aristotle, Timosthenes, and Bion the astronomer, entertain so mistaken an opinion in regard to the winds. They say that the north-east (Cæcias) blows from the commencement of summer, and that the south-west wind (Libs), which is exactly opposite to this, blows from the decline of winter. And again, the south-east wind (Eurus), which is opposite to the north-west wind (Argestes), from the commencement of winter. The east and west winds being intermediate. When our poet makes use of the expression “stormy zephyr,” he means the wind which is now called by us the north-west; and by the “clear-blowing zephyr” our west wind; our Leuconotus is his Argestes-notus, or clearing south wind,[171] for this wind brings but few clouds, all the other southern winds bringing clouds and rain,[172] “As when whirlwinds of the west A storm encounter from the clearing south.”[173] Here he alludes to the stormy zephyr, which very frequently scatters the feathery clouds brought up by the Leuconotus, or, as it is called by way of epithet, the clearing south. The statements made by Eratosthenes in the first book of his Geography, require some such correction as this. 22. Persisting in his false views in relation to Homer, he goes on to say, “He was ignorant that the Nile separated into many mouths, nay, he was not even acquainted with the name of the river, though Hesiod knew it well, for he even mentions it.”[174] In respect of the name, it is probable that it had not then been given to the river, and as to the mouths, if they were obscure and little known, will not every one excuse him for not being aware whether there were several or merely one? At that time, the river, its rising, and its mouths were considered, as they are at the present day, amongst the most remarkable, the most wonderful, and most worthy of recording of all the peculiarities of Egypt: who can suppose that those who told our poet of the country and river of Egypt, of Egyptian Thebes, and of Pharos, were unaware of the many embouchures of the Nile; or that being aware, they would not have described them, were it not that they were too generally known? “But is it not inconceivable that Homer should describe Ethiopia, and the Sidonians, the Erembi, and the Exterior Sea,[175]—should tell us that Ethiopia was divided into two parts, and yet nothing about those things which were nearer and better known?” Certainly not, his not describing these things is no proof that he was not acquainted with them. He does not tell us of his own country, nor yet many other things. The most probable reason is, they were so generally known that they did not appear to him worth recording.[176]
