Main (Thompson) Library location: North wing -- Sixth window. Mathieu Vivan (c.14-- – c. 15--) is believed to be one of the first printers in Orléans, and it is possible that he began his career in Poitiers several years earlier. The only known work attributed to Vivian is Manipulus curatorum, printed in Orléans in 1490. The manual, written by Spanish priest Guido de Monte Rochen, was a popularly produced handbook detailing codes of priesthood. Later documents indicate that Vivian may have had a close involvement in commissions for the city of Orléans. Vivian's mark in the Vassar Library is composed of a heart surmounted by a cross; his initials M.V. form an overlapping monogram within the heart. Above the horizontal bar of the cross are two inscriptions: the first, I.H.S., signifies Jesus, and the second, M, signifies Mary. In the full device, the mark would have been enclosed in a decorative border. Other variations include the Arms of Orléans.
