a Flemish astronomer, cartographer and clergyman. In 1589 he collaborated with the Amsterdam cartographer Jacob Floris van Langren on a 32.5-cm celestial globe, which, using the sparse information available about southern celestial features, for the first time depicted: Crux the southern cross, Triangulum Australe the southern triangle, and the Magellanic Clouds, Nubecula Major and Minor.
