What is "baudolino"

Baudolino is a 2000 novel by Umberto Eco about the adventures of a young man named Baudolino in the known and mythical Christian world of the 12th century.

Baudolino was translated into English in 2001 by William Weaver. The novel presented a number of particular difficulties in translation, not the least of which is that there are ten or so pages written in a made-up language that is a mixture of Latin, medieval Italian and other languages (intended to reconstruct how a barely-literate Italian peasant boy of the 12th Century would have tried to write in the vernacular).
