ANASTASIUS: Antipope 855. As cardinal-priest of St. Marcellus, in Rome, he had been in decided opposition to Pope Leo IV., and from 848 to 850 had been obliged to absent himself from that city. After twice inviting him to appear before a synod, Leo finally excommunicated him (Dec. 16, 850), and pronounced a still more solemn anathema against him at Ravenna (May 29, 853), repeating it in a council at Rome (June 19), and deposing him from his priestly functions (Dec. 8). Anastasius, however, relied on his wealth and his connections in Rome, and aspired to be elected pope on the death of Leo. Leo died on July 17, 855, and the Roman clergy at once chose Benedict III. to succeed him. Anastasius set himself up as a rival candidate. Accompanied by some friendly bishops and influential Romans, he intercepted the imperial ambassadors on their way to Rome, and won them over to his side. On Sept. 21 he forced his way into the Lateran, dragged Benedict from his throne, stripped him of his pontifical robes, and finally threw him into prison. These proceedings, however, caused great indignation in Rome. Not only almost all the clergy, but also the populace sided with Benedict, who was liberated and consecrated (Sept. 29) in St. Peter's. Hergenröther identifies Anastasius with the librarian of the Roman Church of the same name (see ANASTASIUS BIBLIOTHECARIUS), but this seems doubtful. The antipope relied on secular assistance, while the author was a convinced adherent of the strict ecclesiastical party.
