Jean-Jacques Olier (1608‑1657), founder of Saint-Sulpice, hired important painters of his time to adorn the seminary chapel ; the most notable work to be seen there is Charles Le Brun's Pentecost. While the terms of this contract are known, there is in fact little available information on the planned “program,” which remained largely unfinished at the time of Olier’s death. Olier’s spirit, essentially Marian and priestly (the two are related), also inspired an important corpus of engravings. The Sulpician literary tradition, internal to the Company, attributes these images to the founder’s own visions, which, it is claimed, he himself set down as drawings. But none of these has been preserved and, again, little is known about his concrete relationships with the artists.
