A “Savonarola” is‘ A person considered to have the qualities of Girolamo Savonarola, esp. (in early use) a zealous reformer or spiritual leader, or (now more usually) a person who is considered austere, puritanical, or censorious in attitude’ (OED). I have no idea what these sculptures are, but I think they look a bit like Savanarolas.
Day #190 of a 365 project, where the daily pic is informed by the OED word of the day.
