The two folded plates are ca. 24 x 38 cm. and 32 x 25 cm Perrier's dedication precedes title which is repeated as the heading for the index on the final two leaves Library has 6 variations of the work with the same t.p. including date (c. 5 lacks a t.p.) with variations as described by Robert-Dumesnil. Copies also vary as to by-line at the base of Laocoon, plate I: Franciscus Perrier Burgund. delin. et sculp. Romae superior. licentia 1638. Four copies have the 3 printed backwards, unrelated to issue differences of t.p.s. Copy 1 coincides with first issue without any additional remarks under the frame of the symbolic illustration of the frontispiece, and with "1638" under the Laocoon (which faces left). Copy 2 has below the frontispiece frame: Romae superiorum permissu. Cum privilegio summi Pontificis, Robert-Dumesnil's 2nd state, with the Laocoon plate similar to the first with "1638". Details on both engravings similar. Copy 3 frontispiece displays the privilege under the date in 3 lines, and under the frame but within the impression: A Paris; Chez la veusue de deffunct Perier, rue des fossez St. Germain vis a vis l'Hostel de Sourdy. The platemark has been lowered to accommodate: A Paris chez la Ve. de F. Chereau graveur du Roy rue St. Jacques aux deux pilliers d'or avec privilege du Roi. Laocoon plate again faces left with date "1638" Copy 4 has the common frontispiece without additional privilege or printing information, has the backwards 3 under the right facing Laocoon, and a reworked index (bound in after the t.p.) dated An. M.D.C.LIII on the 2nd page. Copies 5 and 6 are incomplete, copy 5 lacking a frontispiece but with the Laocoon plate facing right with the date showing the backward 3. The index has been reworked,and on the 2nd leaf dated An. M.D.C.LIII. The 84 plates of copy 6 are bound in some disorder and with numbering differences when compared with the other copies and with Robert-Dumesnil's arrangement. It also lacks the index. The frontispiece presents the information in first issue context but with some differences in fine detail in the illustrative portion. Laocoon faces right and the date has the backward 3 The images vary in reversal which, together with other variations, encourage the conclusion that the work was printed and reworked over a period of time to meet public demand and that possibly other variations exist in copies held elsewhere.
