Fréart de Chambray completed a translation of the full text of Andrea Palladio's "Quattro Libri" (Venice 1570) into French for the first time. An earlier publication of the first book only, by Pierre Le Muet (1645), had made a very free translation, adjusted to conform to French practice; it proved popular and was freely pirated in the following decades. Publication of Fréart's translation, completed about 1641, which had also been commissioned by his cousin Sublet de Noyers, was delayed as Sublet de Noyers was first disgraced (1643), then died in 1645. Following a stay in Rome, Fréart published it in Paris in 1650. Its "Dédicace à ses frères" is an open letter to his brother connoisseurs and patrons, hoping "to banish this capricious and monstrous fashion of building that some moderns have unhappily introduced as a heresy in the art, by I know not what licentiousness against its precepts and Reason itself". Fréart substitutes his elegant and literate dedication for Palladio's original dedication, and reprints the woodcuts from the Venice edition, which he had brought to Paris for the express purpose.
