Here is one of the more arresting images I’ve come across in the French Revolution Collection (FRC): an engraving of Louis XVI being crucified between the clergy and the nobility.
This messianic image accompanies the pamphlet La passion et la mort de Louis XVI, roi des juifs et des chretiens (Case FRC 27792 and Case FRC 22313). The attribution to Jacques baron de Menou (1750-1810) on page 6 is fictitious, as is the place of publication: certainly not Jerusalem; most likely Paris.
Guy Thuillier recently published a brief discussion and a modern edition of the pamphlet, which is available through JSTOR (Guy Thuillier, “Un pamphlet de 1790 : La passion et la mort de Louis XVI, Roi des Juifs et des Chrétiens de Jean-François de Bourgoing,” La Revue administrative, 58e Année, No. 343 [January 2005], p. 18-24). As Thuillier notes, the pamphlet is attributed to Bourgoing in Notice historique et généalogique sur la famille de Bourgoing by Georges de Soultrait (Lyon: Imprimerie de Louis Perrin, 1855) p. 34 [available via Gallica online]. Soultrait lays three other widely published writings at the feet of Bourgoing: Domine salvum fac regem (1789), Pange lingua (1789), and Le cri de douleur, ou, la journee du 20 juin 1792. All three of these — all of which are in FRC — are attributed by Martin & Walter to Jean-Gabriel Peltier.
Returning to the image, a very similar engraving — but colored and (assuming no inadvertent digital error) reversed — is held by the Musée Carnavalet in Paris, and available online via Bridgeman Art Library.
