 Bishop Federico Cornaro (1561–1577) and his Metropolitan, Archbishop Carlo Borromeo of Milan, both attended the last sessions of the Council of Trent.On his return, Archbishop Borromeo held a provincial synod in Milan in August 1564, which Bishop Cornaro attended, where the decrees of the Council were discussed and adopted as statutes of the ecclesiastical province of Milan.Immediately on his return to Bergamo, Cornaro held his own diocesan synod, on 4–5 September, and announced the imposition of the tax authorized by the Council in its 23rd session (chapter 18), for the purpose of building a seminary for the diocese.
