The Glossa super Baruch, composed in Paris during the late twelfth or early thirteenth century, remains the earliest known Latin commentary on the Book of Baruch, and served as the foundational text for Hugh of St. Cher’s Postilla super Baruch. It is attributed to a certain ‘Dean of Salisbury’, who was most likely a Master trained in the moral biblical school of Stephen Langton, and could be either Richard Poore or Thomas Chobham.
