Main (Thompson) Library location: North wing -- Fourth window. Jean Guyart (c.14-- – c. 15--) was documented working in Bordeaux beginning in 1520, when his name appeared in the colophon of a book written by Guillaume Piellée. During this time he was probably apprenticed to Parisian printer Gaspard Philippe, who worked in Bordeaux on a municipal commission until his death in 1520. Subsequently, Guyart took over Philippe's press and printed his first significant work shortly after – the second edition of Gabriel de Tarrega's Opera brevissima theoricam et prathicam medicinalis, dated 1524. Other notable titles attributed to Guyart are Constitutiones de novo edite correcte revise et emendate by Johannis de Fuxo, Coustumes générallesde la ville de Bordeaux, and Complainte du trop tard marié. This version of Guyart's mark is identical to that of his master, Gaspard Philippe. It consists of an orb, formed by a cursive G, surmounted by a four-mark. A series of letters is inscribed within the "orb," however, their significance remains unknown. Guyart employed a number of full printing devices containing this mark. Many of these illustrated costumed women, enclosed by decorative, floral wreaths; others incorporated images of dolphins.
