The Peruvians not only employed a marly mortar 
in the great edifices of Pacaritambo % but made 
use of a cement of asphalt um (hetun) ; a mode 
of construction^, wliich on the banks of the Eu- 
phrates and the Tigris may be traced back to 
the remotest antiquity. 
The porphyry made use of for the buildings of 
Cannar is cut into parallelopipedons with such 
perfection, that the joints of the stone would be 
imperceptible, as M. de la Condamine remarks^, 
if their exterior surface were a plane ; but the 
outer surface of each stone is slightly convex, 
and cut slantingly towards the edge ; so that the 
joints form small flutings, which serve as orna- 
ments, like the separations of the stones in rustic 
work. This cut of the stone, which the Italian 
architects call bugnato, is found in the ruins of 
Callo, near Mulado, where I have sketched it in 
detail^ : it gives the walls of the Peruvian build- 
ings a great resemblance to certain Roman 
structures, for instance, to the 7nuro di Nerva at 
Rome. 
What chiefly characterizes the monuments of 
Peruvian architecture is the form of the doors, 
which are generally nineteen or twenty deci- 
metres (six or eight feet) high, so that the Inca,
