Gregoire Huret (1606 - 1670). Born in Lyon in 1606, an important center of printing, Grégoire Huret began to engrave at a young age. We do not know the name of his teacher, but tradition recognizes in the early years of Huret's work the influence of Karl Audran, himself known and recognized for his decorative frontispieces. In 1635, he went to Paris and settled in rue Saint-Jacques, which he did not leave until the 1650s. His marriage contract, which took place in 1646, described him as an ordinary designer and engraver of the Maison du Roi. Finally, theAugust 7, 1663, he entered the Royal Academy of Painting and Sculpture, an institution to which he offered in 1664 the Theater of the Passion of Our Lord Jesus Christ. He is thus the fourth engraver to be a member since its creation in 1648. All of his engraved works amounting to nearly 500 numbers, Grégoire Huret died in 1670. Is then published his Optique de portraiture, a work giving a method of treatment of perspective coming into opposition with the method of Abraham Bosse that the latter taught at the Academy until his expulsion in 1661. While very productive in the first fifteen years, from 1635 to 1650 that he spent in Paris, his engraved work no longer contained at the end of his life, from 1656 to 1670, important prints, a notable exception of the Théâtre de la Passion and the frontispiece of the Portraiture Optics.
