344 MURAL ARCHITECTURE 
of the Greeks, only by the joints being sloping, 
instead of vertical, as may be seen in Drawing 
XI.* Some specimens of this are certainly 
found in Htruria, and also at Pompeii, but abound . 
still more in the ruins of ancient Greek walls, as 
at Messalogion, Galaxidi, Delphi, Platea, and 
Pharsalia.+ 
In the examination of these stupendous for- 
tresses, especially those of the Amorphous and 
Polygonal orders, two questions force themselves 
upon our minds :— 
I.— What could have been the inducement of 
the architects to adopt the Polygonal style, which 
would seem to require more skill and labour than 
the regular cubes which the Htruscans employed, 
and which have since been universal ? 
II.—What means could they have possessed, in 
so rude and remote an age, for cutting, raising, 
and transporting such enormous blocks as these, 
which composed their walls ?
