Berengaudus
Berengaudus (840–892) was a Benedictine monk, supposed author of Expositio super septem visiones libri Apocalypsis, a Latin commentary on the Book of Revelation.[2] He has traditionally been assumed to be a monk of Ferrières Abbey, at the time of Lupus Servatus. The attribution has been questioned, but the Expositio was later (by the 12th century) much circulated in manuscript.[3] It was printed in Patrologia Latina vol. XVII under Ambrose, following an attribution by Cuthbert Tunstall.[4]
