Jean-Baptiste Boyer, Marquis d’Éguilles, a French nobleman, was born at Aix, in Provence, in 1650, and was procurator-general of the parliament of that town. His love of the arts led him into an intimacy with the principal artists of his time, particularly with Puget, the celebrated sculptor, with whom he went to Italy, and formed a large collection of pictures, sculpture, &c., of which he published the prints in two volumes; six of the plates were engraved by himself. He also amused himself with painting, for which he is said to have had an excellent taste. He died at Aix in 1709. Some of his plates are executed with the graver, the others scraped in mezzotint. Among others we have by him: The Marriage of St. Catharine; after Andrea del Sarto; with the graver.Two figures of Christ; on one plate; the same.Two Landscapes; after Brecourt; the same.St. John the Baptist; after Manfredi; mezzotint.Bust of a Man; the same.
