The edition is illustrated with a band bearing the arms of the Duc d'Orléans, signed by Nicolas Guérard, and 28 copper-engraved plates, strategically placed at the end of each section to illuminate the text.

The arms of the Duc d'Orléans have been scratched. Provenance: Auguste B. F Gardin de La Pillardière, with handwritten bookplate on title. -P. Hendle, with bookplate.
