. It was almost finished construction in 1185. Pope
Lucius III was elected on 1 September 1181, but had to be consecrated and enthroned at Velletri, due to the hostility of the Romans. But, having refused to grant the
consuetudines to the Romans which had been conceded by earlier popes, he was forced to retreat to Velletri. In the meantime, refugees from
Tusculum, which had been destroyed earlier in the century by the Roman commune, began to rebuild their fortifications. Annoyed by the challenge, the Roman commune reopened the war, devastated the territory of Tusculum in April 1184, and then turned their wrath against Latium. The pope then fled to the Emperor
Frederick Barbarossa, who was at Verona, by way of Ancona, Rimini, Faenza, and Modena. Some of the cardinals followed Pope Lucius to Verona; others, however, whose followers had perpetrated the outrages at Tusculum and in the Roman campagna, remained in the city. Ten cardinals who were with the refugee pope participated in the consecration of the cathedral of Modena on 14 July 1184. They were: Theodinus of Porto, Tebaldus of Ostia; Joannes of S. Marco, Laborans of S. Maria Transtiberim, Pandulfus of Ss. Apostolorum, Ubertus of S. Lorenzo in Damaso; Ardicio of S. Teodoro, Graziano of Ss. Cosma e Damiano, Goffredfus of S. Maria in Via Lata, and Albinus of S. Maria Nuova. Discussions between the pope and the emperor quickly turned sour. There was the matter of lay appointment to bishops, and the issue of the inheritance of
Mathilda of Tuscany, which had been willed to S. Peter, but which was in imperial hands and of which the emperor insisted he was the feudal overlord. Frustrated and angry, the emperor withdrew to the palace in Pavia. He placed a military cordon around Verona, permitting no one to go to the papal court and allowing no one to leave Verona. Anyone caught was subject to imprisonment and torture. ==List of participants==
