330 MURAL ARCHITECTURE 
Both questions are difficult and perhaps impos- 
sible to decide. 
I. The principle of the three styles seems to 
me essentially distinct, and is, I think, generally 
allowed to be so; but some writers conceive at 
least two of them, and perhaps all three, to be 
simply different methods, employed by the same 
people, or the same age, for particular purposes, 
or according to the dictates of caprice, or the skill 
of the individual architect. ‘For,’ they argue 
“the walls of Mycene afford specimens of all the 
three styles, though undoubtedly the polygonal 
predominates.* At Cossa, on the Adriatic, the 
lower part of the walls is polygonal, while the 
upper is arranged in horizontal courses ;f and the 
Treasury of Atreus, at Mycene, exhibits a far 
more perfect specimen of parallel courses of 
hewn stone, than any of the Hirwscan cities can 
furnish.}”
