Vigeant 1882 identifies the first Le Perche witness as a Paris 1676 oblong quarto sold by N. Bonnart, with 35 copper plates and engraved framed text. Although the text is slight and the plates naive, he counts Le Perche among the earliest French authors and regards him as the true creator of the riposte.
