Misvormde ganzen before 1650

This etching by Italian artist Antonio Tempesta depicts two geese, one with two necks and the other with four legs. This anatomical anomaly was likely observed by the natural historian Ulisse Aldrovandi. The artwork’s subject matter reflects the Renaissance fascination with the natural world and the study of its variations. The detailed rendering of the geese's features underscores Tempesta's skill as a draftsman and his interest in depicting scientific accuracy.
