xvii LOCAL WINDS 211 



the equinoctial, the wintry, the one that faces 

 the northern. A sixth is added in the zone which 

 separates the upper part of the world from the 

 lower. As you know, there is always one -half 

 the world above our head, and one -half beneath 

 our feet. This line which lies between the visible 

 and the concealed parts of the sky is called 

 by the Greeks the Horizon (opifav = bounding 

 line) : our school call it the Bounder ; others, the 

 Bounding [line]. To this must be added the 3 

 meridian circle, which cuts the horizon at right 

 angles. Some of these zones run transversely, 

 intersecting others. Now there must necessarily 

 be as many divisions of the heavens as there are 

 parts. So, then, the horizon or bounding circle 

 cuts those five zones, of whose position I have 

 just spoken, making ten parts, five to east and five 

 to west. The meridian circle which meets the 

 horizon gives two additional divisions. Thus the 4 

 air receives its twelve divisions, and yields a like 

 number of winds. 



There are some of the winds that are peculiar to 

 certain localities; they do not carry far, but reach only 

 the immediate vicinity. They do not derive their 

 impulse from a particular quarter of the world at large. 

 For example, the wind Atabulus haunts Apulia ; the 

 lapygian, Calabria ; the Scironian, Athens ; Cataegis, 

 Pamphylia ; Circius, Gaul. To the last mentioned, 

 though it shakes their houses, the people are very 

 grateful, believing they are indebted to it for the 

 healthiness of their climate. At any rate, the late 

 Emperor Augustus, when he was staying in Gaul, 

 erected to it a temple he had vowed. My task 

 would never be done if I were to attempt to 

 enumerate the individual winds. There is hardly
