Horoscopion is a 1533 astrological and sundial treatise by the cartographer Peter Apian, printed at Ingolstadt by his family's press for scholars and instrument makers. Its woodcuts show surveying a tower's height by a shadow and a staff, a sun-shadow diagram of the horizon and earth, and a sundial-style scene with a boat and a fortified town, giving designers clear geometric diagrams with figures.
