[MOLIÈRE]. Lettre sur les observations d'une comédie du Sr Molière, Intitulé Le Festin de Pierre. [Followed by]: Response aux observations touchant le festin de Pierre, de monsieur de Molière. Paris : Gabriel Quinet, 1665. - 2 works in one in-12 volume, blue half-maroquin with bradel corners, smooth spine, not togened (modern binding). Rare first edition of these two texts written in response to the violent criticism of Molière that appeared the same year under the title "Observations sur une comédie de Molière intitulée : le Festin de Pierre". The first text is, according to Guibert (II, p. 799, no. 38), "visibly inspired by Molière and perhaps partly written by him". The second is, according to Guibert (II, p. 799, no. 37), attributable to a friend of Molière's, "more pained than intrigued by the Observations sur le Festin de Pierre". A copy in a modern binding, enriched at the end with two leaves, paginated 1 to 4, containing Molière's poem "Remerciement au roy". Some foxing. The two leaves of Molière's poem are inverted.
