Peritia is devoted to the advancement of medieval studies in the broadest sense of that term (albeit from an insular perspective), including history, languages, law (canon and secular), archaeology and the ancillary disciplines. It is especially strong on Insular Latin, computation, and paleography, and it has carried notable contributions on hagiography, art history and archaeology, literature, Irish vernacular law, and the history of the later Middle Ages. It has a lively and wide-ranging review section.
