Engraving by William Hogarth (1697-1764), showing a satirical view of the medical profesion with the motto 'Et plurima mortis imago' ('And many an image of death') appearing between a pair of crosbones. The engraving is in the style of a mourning card. The three main figures at the top are based on the practitioners Sarah Mapp, Joshua Ward and John Taylor. Beneath these are twelve quack doctors, most of whom are sniffing the heads of their canes, which during the 18th century contained disinfectant. All the faces of these figures are drawn to portray negative characteristics.
