Cardenio between Cervantes and Shakespeare - Roger (College de France) Chartier - Bog

How should we read a text that does not exist, or present a play the manuscript of which is lost and the identity of whose author cannot be established for certain? Such is the enigma posed by Cardenio - a play performed in England for the first time in 1612 or 1613 and attributed forty years later to Shakespeare (and Fletcher).
