Engraved throughout. Title leaf signed by Jean Marot as engraver, 2 leaves signed by Goran. Mauban mentions a copy reported to have 44 leaves, but describes the Bibliothèque des beaux-arts copy with 40 Mauban, A. Jean Marot Getty c. 1 has 35 leaves. It lacks Mauban's nos. 2, 4, 14, 26, 27, 34, 39 and includes 7 additional plates not there listed. Two of these added plates, one with legend "Machine," are printed on leaf [14] along with Mauban's plate no. 19. An added plate with legend "Plan de la Nef de l'ordre Ionique" is printed on leaf [26] along with Mauban's plate no. 30. Leaf [32] has three added plates, two with legends "Vn Regard pour purifier l'eau" and "Figure des arcz renuerses pour metre dans des fondemens soubz des piles ou des colonnes dont le uuide doit estre remply de terre." The last leaf depicts a decorative installation of organ pipes. Its paper differs from that of the other leaves and the image is apparently unrelated to Lavergne's work Getty c. 2 has 40 leaves. Those after the title leaf are numbered in pencil 1-39 at lower right. They include all listed by Mauban except his no. 2. Mauban's nos. 30 & 39 are printed together on the leaf numbered 27. On leaves numbered 36 & 37 there appear the same six additional plates as in c. 1 (i.e., all except the final organ) Binding, c. 1: 19th-century decorated paper, backed in leather, spine title in gilt: VIGNOL[E].
