The church of San Miniato was built by Henry I. of Germany, and Cunegonde his wife. The front is pretty--a kind of mixture of Greek and Arabic architecture, crusted with marble. The interior is in the style of the primitive churches, the altar standing in what was called the _presbytery_, a high platform occupying a third of the nave, with two splendid flights of stairs of the purest white marble. The most curious part of it is the rotunda in the rear, which is lit by five windows of transparent oriental alabaster, each eight or nine feet high and three broad, in single slabs. The sun shone full on one of them while we were there, and the effect was inconceivably rich. It was like a sheet of half molten gold and silver. The transparency of course was irregular, but in the yellow spots of the stone the light came through like the effect of deeply stained glass.
A partly subterranean chapel, six or eight feet lower than the pavement of the church, extends under the presbytery. It is a labyrinth of marble columns which support the platform above, no two of which are alike. The ancient cathedral of Modena is the only church I have seen in Italy built in the same manner.
The _midnight mass_ on "Christmas eve," is abused in all catholic countries, I believe, as a kind of saturnalia of gallantry. I joined a party of young men who were leaving a ball for the church of the Annunciata, the fashionable rendezvous, and we were set down at the portico when the mass was about half over. The entrances of the open vestibule were thronged to suffocation. People of all ages and conditions were crowding in and out, and the sound of the distant chant at the altar came to our ears as we entered, mingled with every tone of address and reply from the crowd about us. The body of the church was quite obscured with the smoke of the incense. We edged our way on through the press, carried about in the open area of the church by every tide that rushed in from the various doors, till we stopped in a thick eddy in the centre, almost unable to stir a limb. I could see the altar very clearly from this point, and I contented myself with merely observing what was about me, leaving my motions to the impulse of the crowd.
