[William] Hogarth might have felt some sympathy for [Sally] Mapp as an ‘irregular’ expert besting pomposity, but this is topped by his sheer relish for her as the Quackest Quack of all, and female to boot. In Hogarth’s print the dark goddess rules over her court of fools, men who have taken over the ancient realm of women’s healing, and now profit from the people’s ills and credulity.
