To-night Signor Scavo, the American Vice-Consul, took me to the palace of Prince Biscari, overlooking the harbor, in order to behold the grand display of fireworks from the end of the mole. The showers of rockets and colored stars, and the temples of blue and silver fire, were repeated in the dark, quiet bosom of the sea, producing the most dazzling and startling effects. There was a large number of the Catanese nobility present, and among them a Marchesa Gioveni, the descendant of the bloody house of Anjou. Prince Biscari is a benign, courtly old man, and greatly esteemed here. His son is at present in exile, on account of the part he took in the late revolution. During the sack of the city under Filangieri, the palace was plundered of property to the amount of ten thousand dollars. The museum of Greek and Roman antiquities attached to it, and which the house of Biscari has been collecting for many years, is probably the finest in Sicily. The state apartments were thrown open this evening, and when I left, an hour ago, the greater portion of the guests were going through mazy quadrilles on the mosaic pavements. Among the antiquities of Catania which I have visited, are the Amphitheatre, capable of holding 15,000 persons, the old Greek Theatre, the same in which Alcibiades made his noted harangue to the Catanians, the Odeon, and the ancient Baths. The theatre, which is in tolerable preservation, is built of lava, like many of the modern edifices in the city. The Baths proved to me, what I had supposed, that the Oriental Bath of the present day is identical with that of the Ancients. Why so admirable an institution has never been introduced into Europe (except in the _Bains Chinois_ of Paris) is more than I can tell. From the pavement of these baths, which is nearly twenty feet below the surface of the earth, the lava of later eruptions has burst up, in places, in hard black jets. The most wonderful token of that flood which whelmed Catania two hundred years ago, is to be seen at the Grand Benedictine Convent of San Nicola, in the upper part of the city. Here the stream of lava divides itself just before the Convent, and flows past on both sides, leaving the building and gardens untouched. The marble courts, the fountains, the splendid galleries, and the gardens of richest southern bloom and fragrance, stand like an epicurean island in the midst of the terrible stony waves, whose edges bristle with the thorny aloe and cactus. The monks of San Nicola are all chosen from the Sicilian nobility, and live a comfortable life of luxury and vice. Each one has his own carriage, horses, and servants, and each his private chambers outside of the convent walls and his kept concubines. These facts are known and acknowledged by the Catanians, to whom they are a lasting scandal.
