In a first visit to a great European city it is difficult not to let many things escape notice. Among several churches which I did not see when I was here before, is that of the _Jesuits_. It is a temple worthy of the celebrity of this splendid order. The proportions are finer than those of most of the Venetian churches, and the interior is one tissue of curious marbles and gold. As we entered, we were first struck with the grace and magnificence of a large heavy curtain, hanging over the pulpit, the folds of which, and the figures wrought upon it, struck us as unusually elegant and ingenious. Our astonishment was not lessened when we found it was one solid mass of verd-antique marble. Its sweep over the side and front of the pulpit is as careless as if it were done by the wind. The whole ceiling of the church is covered with _sequin gold_--the finest that is coined. In one of the side chapels is the famous "Martyrdom of St. Lawrence," by Titian. A fine copy of it (said in the catalogue to be the original) was exhibited in the Boston Athenæum a year or two since. * * * * *
