Copernicus's astronomical treatise De revolutionibus orbium coelestium, printed in Basel in 1566 by the Henricpetri press, is a scholarly work for astronomers that sets out the sun-centred model of the heavens. The four diagrams show geometric circles, lines and lettered points, with a plain black-line style a designer could borrow for technical or schematic work.
