“Far from being a science, mapmaking was still an exercise of fancy, or religious devotion, or fear of the unknown.” 

Cartography was in its infancy at this time. The Renaissance was in its infancy as well, and so many maps at the time were done by religious men. So much of the world was unknown, which was something that people feared.

“The result was that the Great Khan, holding them in high esteem, frequently summoned them to talk with him.” 

The Polos impressed Kublai Khan with their knowledge of the world and their respect for other people and their customs.

This was a lucky charm for the Polos time and again, as having this tablet in the name of Kublai Khan himself enabled them to skip lengthy interrogations and save significant amounts of money on food and accommodations. They could travel in style, where others might have struggled. They also found out just how important that connection was when they had to forgo such protection after the Great Khan died.
