The Leuven Ontology for Aristotelian Diagrams Database

Welcome to the Leuven Ontology for Aristotelian Diagrams Database (Leonardi.DB), a graph-based linked data store of Aristotelian diagrams, based on the eponymous ontology developed as part of the Logical Geometry research programme.

On these web pages, you can perform easy filtered searches for persons, organizations, sources and diagrams, or query the data using our on-site SPARQL editor.
