Main (Thompson) Library location: South wing -- Sixth window. Nicolas du Chemin, originally from Provence, established himself as a printer and engraver at the Sign of St. Michael in Paris in 1540. Before the end of the decade, du Chemin transferred his practice to a press at the Sign of the Silver Griffin, where he worked with Léon Cavellat. Du Chemin developed a number of typesets including musical characters and notes, and accordingly, he specialized in the publication of music books. Some of his music books contained assorted collections of both secular and religious songs; others contained the volumes of contemporary composers, including Clément Janequin, Claudin de Sermisy, and Pierre Certon. Until his death in 1576, du Chemin spent the remainder of his career printing motets and the musical selections for masses. The mark of du Chemin in the Vassar Library consists of the initials, N.D.C. , surmounted by a patriarchal cross with the I.X. monogram for Jesus Christ at the top. This mark commonly appeared on an escutcheon presented by a silver griffin, symbolic of his printing press. Du Chemin employed several other devices throughout the course of his career. For many he used the symbol of a Y – with a flame on the left and a crown on the right – probably to illustrate the choice between the path to hell and to heaven.
