 Radulphus Brito has been identified as the author of two anonymous sets of questions on Aristotle’s Ethics. The first one (previously known as the ‘Vatican commentary’) was ascribed to Brito by Costa after a suggestion by René-Antoine Gauthier (QEN; QE-2008: 99–137). The second set of questions, preserved in a sole manuscript, Vat. Lat. 2173, is still unedited. The first one was written around 1295, when Brito was a master of arts, and the second some years later, most likely when he was studying theology.
