CONCERNING WEATHER SIGNS, 3-4-35 



of winter is also reversed. From whatever quarter 

 cloud streams out from a mountain peak, wind will 

 blow in the direction thus indicated. Clouds which 

 cling to the back of the mountain will also produce 

 wind from the back of it. If there is a girdle * of 

 cloud half way up Mount Athos, and if mountains 

 in general wear such a girdle, there will generally 

 follow a southerly wind. Comets 2 usually indicate 

 wind, arid, if there are many of them, drought is 

 also indicated. After snow 3 a south wind, after 

 hoar-frost a north wind generally blows. Snuff 4 in 

 a lamp indicates wind or rain from the south. 



The points from which the winds come are as 

 they are given in the figure. 5 The winds which 

 most often come on the top of other winds while 

 these are still blowing are the north wind (aparktias)? 

 the north-north-east and the north-west. When 

 however the winds are not dispersed by one another 

 but die down of their own accord, they change 7 to 

 the next winds on the figure, reckoning from left 



Arist. does not seem to distinguish #opeos and airapKrias : his 

 OpaffKlas is T.'s Opavias : his eight principal winds (underlined 

 in diagram) correspond to those represented on the famous 

 Tower of the Winds at Athens, built about two hundred 

 years later.
