Between May 12,1664 and March 15,1669, there took place one of those battles of the theatre without the understanding of which it would be difficult to correctly evaluate the force of the theatre, its ability to adapt, and the limits of its evolution. The premiere of L'lmposteur—written by Molière who, after a none too easy career, was finally being spoiled by the muses and his king (without whom the contribution of the muses would have had less effect)—resulted in the banning of the play and a series of events that finally led to royal permission granting that a completed text be published and presented onstage, a permission under whose grace we still find ourselves. Between the possible premiere and the version considered acceptable, the text was changed several times, proposing even more variants for performance.
