Above is a curious and captivating of two nude jousters -- male and female(?) -- on snails. This is from the Baldus de Ubaldis. Lectura super Institutionibus. 1480-1481. The best part of this image is that it remains an utter mystery as to what sort of allagorical or rhetorical meaning they were trying to express by placing jousting snails in the marginalia. (Most of the images are of armored knights and this is the only one I've ever seen of two nude firghters moving v-e-r-y s-l-o-w-l-y toward each other. I did some internet checking and found this hilarious scholarly debate about the jousting snails. (It reads like something from a Monty Python sketch) And here too -- another attempt at a scholarly debate/discussion what the hell were those monks thinking!
