A research team has amassed a collection of Aristotelian diagrams created between the years of 830 and 2021 and have placed them online.

As part of his research program on logical geometry, Lorenz Demey a philosopher at KU Leuven, his colleague in linguistics, Hans Smessaert, and others have organized the images into a searchable website—the Leuven Ontology for Aristotelian Diagrams Database—with over 3200 diagrams.

Many of the diagrams are straightforward depictions of the square of opposition, but there are a variety of others, some of which are rather artistic. Below are varied samples of some of the more interesting-looking ones (ordered chronologically). Click on the images for further information at their pages in the database:
