Hence the whole perimeter was just about 18
English miles, or less than 16 Italian miles. If, however, a pair of
compasses be run round Taidu and Yenking (as we have laid the latter down
from such data as could be had) together, the circuit will be something
like 24 Italian miles, and this may have to do with Polo's error.
["The Yuen shi states that Ta-tu was 60 li in circumference. The
Ch'ue keng lu, a work published at the close of the Yuen Dynasty, gives
the same number of li for the circuit of the capital, but explains that
li of 240 pu each are meant. If this statement be correct, it would
give only 40 common or geographical li for the circuit of the Mongol
town." (Bretschneider, Peking, 13.) Dr. Bretschneider writes (p. 20):
"The outlines of Khanbaligh, partly in contradiction with the ancient
Chinese records, if my view be correct, would have measured about 50
common li in circuit (13 li and more from north to south, 11.64 from
east to west.") - H. C.]
Polo [and Odoric] again says that there were 12 gates - 3 to every side.
Both Gaubil and Martini also say that there were 12 gates.
