"In twenty five years, the Mongol army subjugated more lands and people than the Romans had conquered in four hundred years... On every level and from any perspective, the scale and scope of Genghis Khan's accomplishments challenge the limits of imagination and tax the resources of scholarly explanation."
"Instead of attacking the walls of Riazan, the Mongols used their massive number of conscripted laborers in a project that confused and terrified the citizens even more. The workers cut down trees, hauled them to the Mongol lines outside the city, and rapidly began building a wall completely surrounding the already walled city."
"The four serpents on the Silver Tree of Karakorum symbolized the four directions in which the Mongol Empire extended... When the khan wanted to summon drinks for his guests, the mechanical angel raised the trumpet to his lips and sounded the horn, whereupon the mouths of the serpents began to gush out a fountain of alcoholic beverages into large silver basins arranged at the base of the tree."
"The Mongols loved competitions of all sorts, and they organized debates among rival religions the same way they organized wrestling matches... Finally, as the effects of the alcohol became stronger, the Christians gave up trying to persuade anyone with logical arguments, and resorted to singing. The Muslims, who did not sing, responded by loudly reciting the Koran in an effort to drown out the Christians, and the Buddhists retreated into silent meditation."
So why didn't any of it last? The same reason so little lasted beyond the fifteenth century AD: the Black Death, which wiped out a fifth of the population of the planet. Having opened up the world from the Pacific to the Mediterranean, the Mongol Empire's extraordinary infrastructure collapsed from the casualties, a victim of its own success. Western Europe meanwhile, protected from the Mongol invasion by its forests, stepped into that world as soon as the coast was clear, and that's what we call the Renaissance. Would read again.
