	Since his time the temper of the Milan Church has been most conservative, and the only alterations in subsequent editions seem to have been slight improvements in the wording of rubrics and in the arrangement of the books. The district in which the Ambrosian Rite is used is nominally the old archiepiscopal province of Milan before the changes of 1515 and 1819, but actually it is not exclusively used even in the city of Milan itself. In parts of the Swiss Canton of Ticino it is used; in other parts the Roman Rite is so much preferred that it is said that when Cardinal Gaisruck tried to force the Ambrosian upon them the inhabitants declared that they would be either Roman or Lutheran. There are traces also of the use of the Ambrosian Rite beyond the limits of the Province of Milan. In 1132-34, two Augustinian canons of Ratisbon, Paul, said by Bäumer to be Paul of Bernried, and Gebehard, held a correspondence (printed by Mabillon in his "Musæum Italicum" from the originals in the Cathedral Library at Milan) with Anselm, Archbishop of Milan, and Martin, treasurer of St. Ambrose, with a view of obtaining copies of the books of the Ambrosian Rite, so that they might introduce it into their church. In the fourteenth century the Emperor Charles IV introduced the Rite into the Church of St. Ambrose at Prague. Traces of it, mixed with the Roman, are said by Hoeyinck (Geschichte der kirchl. Liturgie des Bisthums Augsburg) to have remained in the diocese of Augsburg down to its last breviary of 1584, and according to Catena (Cantù, Milano e il suo territorio, 118) the use of Capua in the time of St. Charles Borromeo had some resemblance to that of Milan.
