As in the depictions>" Malattie della pelle" or the> «Lépreux d’Islande» the illustrated surgical procedures («Médicine opératoire»), “drawn according to the style of N.H. Jacob” around 1800 are of great perfection and beauty. The object of depiction is of course horrifying. The operating hands seem angel-like. The procedure is shown without blood, similar to the sterile and stylized illustrations in emergency instructions on airplanes which stand out because of the omission of the catastrophe.
Both larger works on engravings, which are taken from Diderot’s and D’Alembert’s «Encyclopaedie» and smaller-sized, often almost square pictures with illustrations of surgical procedures are part of the series «Cabinet Anatomique».
