on voyages — but their object is profit not know- 

 ledge ; and in their bHnd engrossment with avarice 

 they do not reflect that knowledge is a more re- 

 liable means even of making profit. Consequently 

 in view of these thousands of persons who go on 

 voyages I will give a more detailed account of the 

 winds than is perhaps suited to the task I have set 

 in hand. 



XLVI. The ancients noticed four winds in all, Desirmntim 

 corresponding to the four quarters of the world (this "/""'"^- 

 is the reason why even Homer mentions no more) — 

 a duU-witted system, as it was soon afterwards 

 considered ; the following age added eight — this 

 system on the other hand was too subtle and meticul- 

 ous. Their successors adopted a compromise, adding 

 to the short Ust four winds from the long one. There 

 are consequently two winds in each of the four 

 quarters of the heaven : Subsolanus blowing from 

 the equinoctial sunrise (E). and Vulturnus from the 

 winter sunrise (S.E.) — the former designated by the 

 Greeks ApeUotes, the latter Eurus ; Auster from the 

 sim at midday (S.) and Africus from the winter sunset 

 (S.W.) — named in Greek Notus and Libs ; Favonius 

 from the equinoctial sunset (W.), Corus from the 

 sunset at the solstice (N.W.) — these the Greeks call 

 Zephyr and Argestes ; Septentrio from the North 

 and Aquilo between him and sunrise at the solstice 

 (N.E.) — called in Greek Aparctias and Boreas.

 these : Thrascias (N.N.W.) in the space between 

 Septentrio (N.) and the sunset at the solstice (N.W.) 

 and also Caecias (E.N.E.) in the space between 

 Aquilo (N.E.) and the equinoctial sunrise (E.) on the 

 side of the sunrise at the solstice, and Phoenix
