Invisible Cities deconstructs an archetypal example of the
travel literature genre,
The Travels of Marco Polo, which depicts the eponymous Venetian merchant's journey across
Asia and in
Yuan China (
Mongol Empire). The original 13th-century travelogue shares with Calvino's novel the brief, often fantastic accounts of the cities Polo claimed to have visited, along with descriptions of the city's inhabitants, notable
imports and exports, and stories by Polo about the region.
Invisible Cities is an example of Calvino's use of
combinatory literature, and shows influences of
semiotics and
structuralism. In the novel, the reader finds themself playing a game with the author, wherein they must find the patterns hidden in the book. The book has nine chapters, but there are also hidden divisions within the book: each of the 55 cities belongs to one of eleven thematic groups (explained below). The reader can therefore play with the book's structure, and choose to follow one group or another, rather than reading the book in chronological chapters. At a 1983 conference held at Columbia University, Calvino himself stated that there is no definite end to
Invisible Cities because "this book was made as a
polyhedron, and it has conclusions everywhere, written along all of its edges." ==Structure==
