The Blunderer is generally believed to have been first acted at Lyons in 1653, whilst Molière and his troupe were in the provinces. In the month of November 1658 it was played for the first time in Paris, where it obtained a great and well-deserved success. It is chiefly based on an it comedy, written by Nicolo Barbieri, known as Beltrame, and called L'Inavvertito, from which the character of Mascarille, the servant, is taken, but differs in the ending, which is superior in the it play.
