Whilst Constantine was in prison, there was an attempt to install another antipope,
Philip, followed by the election of
Pope Stephen III. After his election, followers of the new pope began attacking key members of Constantine’s regime, including Bishop Theodore, the
Vice-dominus and Constantine’s brother, Passivus, both of whom were blinded. Constantine was taken from prison, put on a horse and driven through the city on top of a
woman’s saddle, with heavy weights attached to his feet, among jeering crowds. There was still support for Constantine, however. The town of
Alatri, under the leadership of its governor, Gracilis, who held the title of a
Tribune, They prohibited anyone from giving him aid; after 24 hours, however, complaints from the people prompted the monks to re-imprison him in the monastery. In April 769,
Pope Stephen III opened a new
Lateran Council; a major topic for discussion was the elevation of Constantine. The blinded prisoner was brought before the council, where they questioned his elevation to the
Apostolic See when he was still a layman. Constantine responded that he had been forced to take on the role, as the Roman people had been looking for someone to fix the problems left behind by
Pope Paul I. He then confessed to the charges, and threw himself on the mercy of the synod. ==Notes==
