How does Marco Polo use imagery in The Travels of Marco Polo?

Imagery:

"ARMENIA Major is an extensive province, at the entrance of which is a city named Arzingan, where there is a manufacture of very fine cotton cloth called bombazines, as well as of many other curious fabrics, which it would be tedious to enumerate. It possesses the handsomest and most excellent baths of warm water, issuing from the earth, that are anywhere to be found."
