(Antipope Innocent III)
Schismatic Cardinal Lando , deacon of S. Angelo in Pescheria, was set up as Antipope Innocent III on September 29, 1179.
This is the account of the event by Mann, The Lives of the Popes in the Middle Ages.
The Popes at the Hight of their Temporal Influence, Innocent II. to Blessed Benedict XI., 1130-1305 , vol. X, 1159-1198 , p. 137: "a few of the unruly barons of the Campagna had the effrontery to attempt to set up a certain Lando of Sezza as Innocent III.
His chief supporter was a brother of Antipope Octavian.
Out of hatred of Alexander, this baron gave Lando a strong castle he had at Palombara, and from which the antipope ravaged the neighbourhood. Cardinal Hugo, however, in a few months contrived to get possession of the fortress by bribing its defenders, and the miserable Lando, with his chief adherents, was shut up for life in the monastery of La Cava (January 1180)."
