Jean Papillon, wood-engraving firm (Paris)
The family firm of the Papillons flourished over three centuries. Giles Barber has valuably identified locations of Papillon ornaments (including small butterflies) in several unusual and clandestine books circulating on the Continent, particularly France; see Barber, "Flowers, The Butterfly, and Clandestine Books," Bulletin of the John Rylands University Library of Manchester 68, no. 1 (1985): 11-33, ills. Barber's "butterfly" is not Lady Villiers, but rather Jean-Michel Papillon.
