220 ARCHITECTURE. 
6. Persia. The Bridge of Barbaruh at Ispahan over the Senderuth 
(fig. 8, the length ; jig. 4, front view; jig. 5, section of the side) is named 
from its builder, and is of an unknown antiquity. It is 2250 feet long, 120 
feet high, and 156 feet broad. The middle way, 60 feet broad, and the side 
ways are paved with marble, and the latter lead through arcades, to which 
the ascent is by stairs in the four towers of the bridge. ‘These stairs also 
lead under the bridge, where a way leads along the length of the bridge 
through the pillars, as the substructure reaches to the surface of the water, 
which flows only through bridged canals. The bridge has 29 arches of 50 
feet span, and the pillars are 25 feet thick. 
7. Cutna. The Chinese bridges have generally huge proportions, as, for 
instance, the Bridge of Loyang, which is 26,800 feet long, and that of 
Focheu, which is 22,000 feet long, and both are 60-70 feet wide. We 
have represented two specimens of Chinese bridges in jigs. 19 and 20, one 
with pointed, the other with round arches. These two bridges prove that 
the usual simplicity of Chinese bridges is not owing to ignorance of the art 
of vaulting, which on the contrary the Chinese appear to possess in 
perfection.
