This article takes up what and how maps might have taught a Crown Prince in the century before maps became a part of classrooms and Mercator’s system of projection engendered those collective perceptions of space and person that have become a part of a modern shared spatial imagination. The focus of this article is a single codex, utterly unique, which scholars have posited was compiled in 1570 to accompany the Crown Prince of Jülich-Cleves-Berg on his Italian trip. This article argues that this codex was designed to teach him practices of spatial imagination, a concept this article introduces.
