No attempt was made to introduce it into England . Pius IV sent the decrees to Mary, Queen of Scots, with a letter dated 13 June 1564, requesting her to publish them in Scotland, but she dared not do it in the face of John Knox and the Reformation . </P> <P> These decrees were later supplemented by the First Vatican Council of 1870 . </P> <P> The most comprehensive history is still Hubert Jedin's The History of the Council of Trent (Geschichte des Konzils von Trient) with about 2500 pages in four volumes: The History of the Council of Trent: The fight for a Council (Vol I, 1951); The History of the Council of Trent: The first Sessions in Trent (1545--1547) (Vol II, 1957); The History of the Council of Trent: Sessions in Bologna 1547--1548 and Trento 1551--1552 (Vol III, 1970, 1998); The History of the Council of Trent: Third Period and Conclusion (Vol IV, 1976). </P>
