Putting together these indications, I think we must conclude that the Boreas of Homer is a wind to the east of north. But it seems plain that he does not embrace nearly the whole quadrant from north to east. For, like and even more than Zephyr on the other side of the pole, he has a leaning towards the polar side, and, in the absence of more particular marks, Homer should be taken to mean by him a N.N.E. wind, that is, a wind ranging principally or wholly from N. to N.E. I take the line Il. ix. 5, which many have treated as a difficulty, for a sound and valuable geographical indication. Boreas and Zephyr blow from Thrace. To a Greek, say at Mycenæ, Thrace, which reaches from the Adriatic to the Euxine, covers more than ninety degrees of the horizon. It is from within those ninety degrees that every Boreas, and probably every Zephyr, of Homer can be shown to blow. These are facts which we may hold in deposit, ready for service in the explanation of the movements of the Outer Geography. And along with them we must keep in mind the Homeric affinity and sympathy established between Boreas and Zephyr. It is so considerable, and they are especially in such local proximity, that practically we should not go far wrong were we to say Homer divides the whole circumference of his horizon into three nearly equal arcs of 120 degrees, more or less. The first of these, beginning from due west, is given to Zephyr and to Boreas. The next, reaching to within 30° of the South Pole, to Eurus: and the third, embracing the residue of the circle, to Notus. ~_Points of the Compass for Notus and Eurus._~ Notus is the great southern wind, Eurus being comparatively of little account. Now, one of the chief _data_ applicable to determining the direction of these winds is the passage Il. ii. 144-6. Here they are described as disturbing the Icarian Sea, which was within the sphere of Greek navigation. Now the position of that sea, on the coast of Asia Minor to the south of Samos, shows, 1. That both these winds in Homer have a decidedly southern character. 2. That one, of course Eurus, must come from the east, and the other, Notus, in that place, from the west of south. Because the conflict of the two winds presumes a considerable space between the points from which they blow, while the position of the Icarian Sea requires both to be southern. But in the Fifth Odyssey, too, Notus is treated as the proper antagonist of Boreas. His centre therefore lies a little to the westward of due south; but Eurus does not approach the South Pole, and every wind from about S.S.E. to W. will probably fall within the Homeric description of Notus.
