De ente et essentia (transl. On Being and Essence) was written by scholastic philosopher and Catholic saint Thomas Aquinas (1225–1274) between approximately 1252 and 1256. It explains the metaphysical relationship between a thing's esse (being), or "whatness", and its essentia (existence), or "is-ness".[1]
The earliest commentary on De ente et essentia was written by Conrad of Prussia before 1323.[2] Other commentators include Armand de Belvézer, Gennadios Scholarios, Gerardus de Monte, John Versor, Jan of Głogów, Thomas Cajetan, Peter Crockaert, Girolamo Contarini and Raphael Riva.[3]
