And we may add Aquilo (north), which has no place in the famous battle of the winds to which Virgil refers. Some make the number of the winds twelve. They divide the four quarters of heaven into three parts each, adding two subsidiary winds to each of the principal ones. On this principle that diligent author, Varro, classifies them. And 3 there is good ground for it; the other method, which refers them to seasonal changes, is very unsatisfactory. For instance, the sun does not always rise or set at the same point. He has one place of rising at the equinox--indeed, the equinox occurs twice a year--another at the summer, and still another at the winter, solstice. The wind which sets in from the direction of sunrise at the equinoxes is with us called Subsolane (near the sun); the Greeks call it ἀφηλιώτης (from the sun). From sunrise in winter Eurus comes, named by our countrymen Vulturnus (_i.e._ from Mt. Vultur in the S.E.). Livy also calls it 4 by this name, in connection with that famous battle of Cannae, which proved so disastrous to Rome. Hannibal on that occasion managed to get our army with its face to the rising sun and to the wind; by the aid of the wind and the glare that dazzled the eyes of the enemy he snatched the victory. Varro likewise uses the same name. But Eurus is a name now naturalised, and has a place in our vocabulary that does not suggest any foreign origin. The wind that is raised by sunrise at the 5 summer solstice was called by the Greeks καικίας;[75] we have no name for it. Sunset at the equinox sends us Favonius, which even people who cannot speak Greek will tell you is called the Zephyr. Corus, which is by some called Argestes [from its clearness], comes from the sunset at the summer solstice. I do not approve of the identification; Corus is a vehement wind, rushing in one uniform direction, while Argestes is, as a rule, a gentle wind, and blows impartially on travellers coming and going along the same road (_i.e._ is constantly 6 shifting). From sunset in midwinter comes the rushing furious Africus (African wind), named by the Greeks the Libyan (λίψ). In the northern quarter the highest (_i.e._ most easterly) is Aquilo, the central one is Septemtrio, the lowest Thracias,[76] for which there is no corresponding word in Latin. In the southern region there is Euronotus, then Notus, or in Latin Auster, then Libonotus, which has no Latin name. [75] No explanation of this name of the nor’-easter is forthcoming. [76] _I.e._ the Thracian; Thrace must have been N.W. of the region in which the name had its origin. XVII
