Artifex Ars Cartographica: Collaboration Between Portuguese Painters and Cartographers in the Fifteenth and Sixteenth Centuries

open access: yesRenaissance Studies, EarlyView.
ABSTRACT During the fifteenth and sixteenth centuries, there was no statutory difference between cartography, drawing and painting. These activities were performed then by craftsmen who were part of a vast group under the umbrella of ‘mechanical arts’ and fell under the ‘artifex’ category. Artifex were experts in any particular art, whether a craftsman,
