© Science Museum / Science & Society Picture Library
Title page, drawn and engraved by Schoonebeek, from 'Traittez des Barometres, Thermometres et Notiometres ou Hygrometres' (1688) by Joachim d'Alence. This allegory shows barometers and hygrometers being demonstrated to Cupid and Mercury, while Apollo rides past in glory. The book is a pocket-sized treatise about the barometer, thermometer and hygrometer. Its 35 plates are rare early illustrations of 'natural philosophers' (scientists) at work.
