So, you learn something everyday! A post at the Folger Library's blog by John Hunt (University of Louisville) discusses a 1670 map ~ with several vignettes ~ designed to inform a growing public about the rituals and procedures of Papal Conclaves. Today, we have breathless commentary by journalists that barely hides their frustration at not being able to be present within the conclave; then, interested members of the public could imagine the process with the aid of this map.
Several other seventeenth-century maps and views of Papal Conclaves can be consulted on the Folger Library's digital collections.
