"Invisible Cities" is a novel by Italian writer Italo Calvino, first published in Italy in 1972 by Giulio Einaudi Editore. The story is framed as a conversation between the Mongol emperor Kublai Khan and the explorer Marco Polo. Most of the book consists of short prose poems describing 55 imaginary cities, narrated by Polo, which reflect on culture, language, time, memory, death, and the human experience. This project spawned from a trip on the Orangle Line to Midway Airport in Chicago. Not as expansive as Marco Polo’s ventures, but an adventure nonetheless.
