If Herodotus must be blamed at all, it is for supposing that the Hyperboreans were so named in consequence of Boreas, or the north wind, not blowing upon them. The poets are allowed much licence in their modes of expression; but their commentators, who endeavour always to give us the correct view, tell us that the people who dwelt in the extreme north, were styled Hyperboreans. The pole is the boundary of the northern winds, and the equator of the southern; these winds have no other limit. 23. Eratosthenes next finds fault with the writers who fill their narrative with stories evidently feigned and impossible; some as mere fable, but others as history, which did not deserve mention. In the discussion of a subject like his, he should not have wasted his time about such trifles. Such is the way in which this writer completes the First Book of his Memoirs. CHAPTER IV. 1. In his Second Book Eratosthenes endeavours to correct some errors in geography, and offers his own views on the subject, any mistakes in which we shall endeavour in our turn to set right. He is correct in saying that the inductions of mathematics and natural philosophy should be employed, and that if the earth is spheroidal like the universe, it is inhabited in all parts; together with some other things of this nature. Later writers do not agree with him as to the size of the earth,[442] nor admit his measurement. However Hipparchus, when noting the celestial appearances for each particular locality, adopts his admeasurements, saying that those taken for the meridian of Meroe,[443] Alexandria, and the Dnieper, differ but very slightly from the truth. Eratosthenes then enters into a long discussion concerning the figure of the globe, proving that the form of the earth together with the water is spheroidal, as also the heavens. This however we imagine was foreign to his purpose, and should have been disposed of in the compass of a few words. 2. After this he proceeds to determine the breadth of the habitable earth: he tells us, that measuring from the meridian of Meroe[444] to Alexandria, there are 10,000 stadia. From thence to the Hellespont[445] about 8100. Again; from thence to the Dnieper, 5000; and thence to the parallel of Thule,[446] which Pytheas says is six days’ sail north from Britain, and near the Frozen Sea, other 11,500. To which if we add 3400 stadia above Meroe in order to include the Island of the Egyptians,[447] the Cinnamon country, and Taprobane,[448] there will be in all 38,000 stadia.
