In 1543, Nicolaus Copernicus declared the earth revolved around the Sun, overturning centuries of scholastic presumption. A new age was coming into view – one guided by observation, technology and logic. But omens and elixirs did not disappear from the sixteenth-century laboratory.

From the icy Danish observatory of Tycho Brahe, to the smoky, sulphur-stained workshop of John Dee, Violet Moller tours the intellectual heart of early European science. Exploring its rich, multidisciplinary culture, this reveals a dazzling forgotten world, where all knowledge, no matter how arcane, could be pursued in good faith.
