Capranica, having already suffered severe losses at Rome through the enmity of the Orsini, took refuge first with Filippo Maria Visconti of Milan and later appealed (1432) to the Council of Basle for recognition of his title. Among his entourage when he left for Basel was Enea Silvio Piccolomini, the future Pope Pius II. The Basel assembly recognized Capranica's promotion, but to punish him for adhering to the council Eugene IV deprived him of all honors and dignities, also of his possessions. Capranica sought a reconciliation with the pope at Florence (30 April 1434). Eugene restored to him his offices and goods, assigned to him the cardinal's church of Santa Croce in Gerusalemme, and sent him to the Council at Ferrara with a special commission to treat with the Greek bishops and theologians concerning the reunion of the Churches.
