1588; his second was held on 7 November 1591 and his third on 18 November 1593; he had announced a fourth, but died before it was held. These synods were important for the implementation of the decrees of the Council of Trent. Bishop Giovanni Stefano Ajazza (1596–1618) published Constitutions and decrees from his first diocesan synod held on 23 October 1597; he took care to have his own and papal decrees published in Italian translation; he held his second synod on 24 October 1601, and his third on 19 April 1605. Bishop Isidoro Pentorio, (1619–1622) held a synod in 1620. Others were held by Bishop Ottavio Broglia (1624–1647) on 22 April 1627, 17 May 1634, 5 November 1643, and in 1646; by Bishop Paolo Vincenzo Roveria (1655–1665) on 13 December 1660; by Bishop Marco Antonio Tomati (1666–1693) on 14 April 1670 and in 1677; by Bishop Innocenzo Migliavacca (1693–1714) in 1699; by Bishop Giovanni Todone (1727–1739) on 29 August 1730; and by Bishop Paolo Caissotti (1762–1786) on 29 June 1785. Statutes and decrees were published in each case. Cathedral and Chapter The original cathedral was destroyed in 1073. Its successor was dedicated by Pope Urban II, perhaps in 1096. The third was begun by Bishop Guido de Valperga (1295–1327) in 1295, or perhaps in 1309 or 1323 or 1333. It was completed in 1768. Bishop Hilduinus had been present at the election of the Emperor Charles the Bald as King of Italy in 876, and had consented to the regulations enacted at the time. One of them declared that bishops should provide next to their cathedral an enclosed space (claustrum) in which they and their clergy should serve God according to a Canonical Rule. No evidence indicates whether his commitment went beyond his signature, but Canons existed in Asti thirty years later. On 7 May 907, Pope Sergius III confirmed, at Bishop Audax' own request, all the possessions, rights and privileges which Bishop Audax had granted to the Canons. On 25 July 1169, the Canons themselves obtained a papal bull from Pope Alexander II, taking their corporation and its property under the protection of the Holy See. The bull lists a considerable number of estates and properties that belonged to the Cathedral Chapter at that time. One of the celebrated members of the Chapter was the Archpriest Uberto de Cocconato, who became a Cardinal in 1261 and participated in four
