The city during its early wars was several times sacked, and more than once burnt by the Bavarian hordes which overran the country and even at last reached the gates of Rome itself. Thus Trent came to be built at various periods upon former foundations, and researches of recent times have tended to show that, as was the case with Rome itself, the comparatively modern Trent is built upon soil several feet above the level of its first site. One Italian authority, indeed, states that the streets of the original town lie some fourteen feet below the level of those of the present. Traces of at least three distinct lines of walls marking the growth of the city at various times have been excavated, leading also to the discovery of many interesting relics of Roman days, including tessellated pavements, portions of an amphitheatre of considerable size, ornaments, household utensils, etc. The bishops still retain their title of Prince, but they lost their power as territorial rulers at the time of the secularization which took place throughout Tyrol, and also in the principality of Salzburg. [Sidenote: THE COUNCIL OF TRENT] Although this ancient city, which is characterized nowadays by a cleanliness and order so often found wanting in Italian towns, has undergone many vicissitudes and has been the scene of important historical events, to the Trent folk of to-day and to many of the visitors who come to it the chief events in connection with its history will undoubtedly remain the sittings of the famous Council which commenced in the year 1545. Many may wonder how it came about that so comparatively small a town should have been chosen as the meeting-place of a Conference intended to attempt the co-ordination of the beliefs and doctrines and the regulation of ecclesiastical affairs of the whole of the then Christian world. Probably the sole reason for this selection was the geographical position of the city, which lay then, as it does to-day, a frontier town, so to speak, between Italian and German influences, and though situated on Austrian soil, yet containing an Italian-speaking population. The Council opened on December 13, 1545, and continued its sittings (with interruptions) until December 4, 1563, the last being the twenty-fifth in number. The meetings of the Council took place at various times during the reigns of three Popes, Paul III., Julius III., and Pius IV., and amongst the enactments of the Council the Canon of Scripture, including the Apocrypha, was confirmed, and the Church named as its sole interpreter; that traditions were to be considered as equal with Scripture, and the seven sacraments of Baptism, Confirmation, the Lord's Supper, Penitence, extra-Unction, Orders, and Matrimony were also confirmed; transubstantiation, Purgatory indulgences, celibacy of the clergy, auricular confession, and other matters were dealt with.
