Circular Thinking is an online lecture, short papers and panel discussion devoted to the drawing compass, an essential tool of premodern makers that came to represent divine Creation. Although now associated primarily with architecture, the compass was a transmedial instrument, integral to a range of artisanal operations, yet evidence of its use is relatively thin. Through discussion and close study of historical evidence, Circular Thinking seeks to impart a more precise understanding of the compass’s varied uses — in measurement, scaling, copying and the generation of diverse shapes in two and three dimensions — and, with this, its symbolic force. The programme is made possible through the generous support of the Warburg Institute and the Leverhulme Trust.
