The circumstances of Adalbert's
election are difficult to ascertain. It took place in the basilica of
Santi Apostoli. According to the German chroniclers
Frutolf of Michelsberg and
Ekkehard of Aura, the Emperor
Henry IV intervened to secure Adalbert's nomination, although sources nearer in space and time to events do not mention the emperor. The
Annales Romani, the richest source of information on Adalbert's pontificate, states simply that he was elected by that part of the clergy and people of Rome who had sided with Clement III. Adalbert's first public appearance drew a large crowd and rapidly degenerated into unrest. The situation eventually got so bad that he was forced to take refuge in the basilica of
San Marcello al Corso under the protection of Romano and Giovanni Oddoline. Many clergy who tried to reach the church were beaten and stripped naked by the mob. Paschal II then bribed Giovanni to hand the antipope over. Adalbert was stripped of his pallium and handed over to Paschal's forces. His pontificate had lasted 105 days. He was led behind a horse (as a sign of contempt) to the Lateran Palace, where Paschal was residing. He was then imprisoned in a tower. The
Annales Romani and the biography of Paschal in the
Liber pontificalis agree that the acceptance of the bribe and the antipope's imprisonment took place in the space of one day. Adalbert was eventually sent to the
Benedictine monastery of San Lorenzo in
Aversa, where he spent the rest of his life. The date of his death and the place of burial are not known. In 1105, the pro-Imperial party elected Maginulf as
Sylvester IV in opposition to Paschal, but he was no more successful than his predecessors for he too lacked imperial support. ==References==
