The seventeenth-century illuminator of the colophon-page, who was probably associated with the Rocolet Bindery, replaced the metalcut armorial device (often employed by Hardouyn, but still not satisfactorily explained) with the arms of Pierre Séguier (1588-1672), comte de Gien, garde des sceaux, one of the founders of the Académie française and one of France's greatest bibliophiles; the equally unexplained initials on the sphere he replaced with the monograms PS and MF (Séguier's wife Madeleine Fabri).

The bindery that worked for the publisher and Royal stationer, Pierre Rocolet, was one of the two most important ateliers in mid-seventeenth-century Paris (the other being that of Florimond Badier), and this is undoubtedly one of its most elaborate and finest productions.
