In this slight book I found poetry, philosophical discourse, the stakes to a game of chess, and one of the finest last lines to a novel: "...seek and learn to recognize who and what, in the midst of the inferno, are not inferno, then make them endure, give them space." A beautiful affirmation of humanity! This novel abounds with thoughtful and deep-inside-wrenching remarks, interlaced with poetic descriptions of countless imaginary cities that live and breath the characteristics of the all-too-real cities of the world today. The progression of city-experiences in this novel reminded me a little of the snapshot scenarios in Calvino's Marcovaldo. BUT, this book is still completely different! This book spurred my own imagination as Marco Polo's and Kublai Kahn's are intertwined within the covers. A wonder at many different levels and will be added to the very short list of books that I re-read every few years.
