Mastectomy, attributed to a Dutch artist, 17th century

The operator excises the breast with the "tenaculum helvetianum". His assistant has a case of lancets etc. attached to his belt. A set of cautery irons is smouldering on a stand on the left. The patient is seated, held by two men: she appears to be fainting. On the right, a man in a tall hat points towards her: he is possibly meant to be a physician.
