Such was the condition of the circle on the Aventine, when a great event happened in Rome. Following many struggles and disasters in the East, chiefly the continually recurring misfortune of a breach of unity, a diocese here and there exhibiting its freedom by choosing two bishops representing different parties at the same time, and thus calling for the exercise of some central authority--Pope Damasus had called a council in Rome. He was so well qualified to be a judge in such cases that he had himself won his see at the point of the sword, after a stoutly contested fight in which much blood was shed, and the church of S. Lorenzo, the scene of the struggle, was besieged and taken like a castle. If he had hoped by this means to establish the universal authority of his see, a pretension as yet undeveloped, it was immediately forestalled by the Bishop of Constantinople, who at once called together a rival council in that place. The Council of Rome, however, is of so much more importance to us that it called into full light in the Western world the great and remarkable figure of Jerome: and still more to our record of the Roman ladies of the Aventine, since it suddenly introduced to them the man whose name is for ever connected with theirs, who is supposed erroneously, as the reader will see, to have been the founder of their community, but who henceforward became its most trusted leader and guide in the spiritual life.
