Main (Thompson) Library location: End window -- North wing. Léon Cavellat (c.15-- – c. 1610) belonged to a prominent family of printers; he and his brothers Pierre and Jean were the sons of printer Guillaume Cavellat. Beginning in 1577, Léon Cavellat worked in Paris at the Sign of the Silver Griffin, in a printing firm that he assumed from Nicolas du Chemin. The first work attributed to Cavellat is entitled Divers poemes latins et francois, printed in 1578. He primarily published works of contemporary literature, including the works of poet Pierre de Ronsard, as well as a number of political and religious documents. The mark of Léon Cavellat in the Vassar Library displays the printer's monogram as the basis for an intricate symbol. The overlapping initials L.C. serve as the base of an equilateral cross, surmounted by a traditional four-mark and accented with multiple horizontal bars. In fuller versions of the device, Cavellat employed illustrations of griffins and cherubim to bear the heraldic shield containing his monogram. Many of Cavellat's devices resemble those of du Chemin.
