This is a black and white engraving depicting a medical procedure from the 17th or 18th century. **Main Scene:** A man (A) is seated in a wooden chair, his left arm bared and extended. A second man, dressed in a long coat and wig, is performing a bloodletting procedure on the seated man. He is holding a long, cylindrical instrument (E) with a pointed end, inserted into the seated man's arm. A small animal, possibly a piglet (B), is positioned near the seated man's arm, with the instrument also seemingly penetrating its neck (D). This suggests a comparison or demonstration of the procedure on both human and animal. **Setting:** The scene takes place indoors, with a table covered by a draped cloth. On the table, there is a rolled-up cloth, a small plate, and a bowl. **Details:** The engraving style is detailed, with cross-hatching used to create shading and texture. There are labels (C and E) pointing to different parts of the instrument. The seated man appears stoic, while the other man is actively engaged in the procedure. The floor is covered with a patterned rug. **Text:** The top right corner of the image contains the text “Part. 3. Cap. 40.”, likely indicating a chapter or section number from a medical text.
