 As might be naturally expected from the exegetical methods of his day, Haymo is not an original commentator; he simply repeats or abridges the Scriptural explanations which he finds in patristic writings.As a pious monk, and a faithful observer of Rabanus's recommendations, he writes almost exclusively about the moral and mystical senses of the sacred text.He is also the author of an "Epitome" of Eusebius's "Ecclesiastical History", of a large number of sermons, and of a spiritual work, "De amore coelestis patriae".
