4 March 1363 he was excommunicated once more, together with his children, one of whom, Ambrogio, was captured by the Papal commander Gil de Albornoz. With the peace signed on 13 March 1364, Visconti left the occupied Papal lands, in exchange for the raising of the ban upon a payment of 500,000 florins. In spring 1368 Visconti allied with Cansignorio della Scala of Verona, and attacked Mantua, still ruled by Ugolino Gonzaga. The situation was settled later in the year through an agreement between him and emperor. Two years later he besieged Reggio, which he managed to acquire from Gonzaga in 1371. The following war against the Este of Modena and Ferrara raised again Papal enmity against the Milanese, now on the part of Gregory XI. In 1370, he ordered the construction of the Trezzo Bridge, then the largest single-arch bridge in the world. In 1373, the pope sent two papal delegates to serve Bernabò and Galeazzo their excommunication papers (consisting of a parchment bearing a leaden seal rolled in a silken cord). Bernabò, infuriated, placed the two papal delegates under arrest and refused their release until they had eaten the parchment, seal, and silken cord which they had served him. He managed to resist, despite also the outbreak of a plague in Milan, whose consequences he suppressed with frantic energy. In 1378 he allied with the Republic of Venice in its War of Chioggia against Genoa. His troops were however defeated in September 1379 in the Val Bisagno. Bernabò, whose despotism and taxes had enraged the Milanese, is featured among the exempla of tyrants as victims of Fortune in Chaucer's Monk's Tale as "god of delit and scourge of Lumbardye". He was deposed by his nephew Gian Galeazzo Visconti in 1385. Imprisoned in the castle of Trezzo, he died on 19 December of that year, presumably poisoned. Bonino da Campione sculpted the equestrian statue of Bernabò Visconti for the church of San Giovanni in Conca around 1363. Its positioning near the church's main altar was regarded as highly problematic by contemporaries and it was commented on by poet and intellectual Petrarch among others. The equestrian statue was reused – with changes and additions carried out by the same Bonino in 1385–1386 – as Bernabò's funerary monument in the same church. It is now preserved in the Castello Sforzesco in Milan. An erratic small-size male head in marble now in
