A bridge of boats unites the two banks, and connects the suburbs with the town. You cross it in order to visit, near Santi-Pouce, the remains of Italica, the birthplace of the poet Silius Italicus, and the emperors Trajan, Adrian, and Theodosius: there is a ruined circus, whose form is still tolerably distinct. The cellars where the wild beasts were confined, the dressing-rooms of the gladiators, as well as the lobbies and rows of benches, can be made out with the greatest facility. The whole is built of cement, with flint-stones embedded in it. The stone coating has probably been torn away to serve in more modern edifices, for Italica has long been the quarry of Seville. A few chambers have been cleared out, and afford a shelter during the great heat of the day to herds of blue pigs, who run grunting between the visitors' legs, and are now the only inhabitants of the old Roman city. The most perfect and most interesting vestige of all this splendour that has for ever disappeared, is a large mosaic, which has been surrounded by walls, and represents Muses and Nereids. When it is revived with water, its colours are still very brilliant, although the most valuable stones have been torn out from motives of cupidity. Among the rubbish, some fragments of very tolerable statues have likewise been found, and there is no doubt that skilfully directed excavations would lead to important discoveries. Italica is situated about a league and a half from Seville, and the excursion there and back may be easily made with a calessin in an afternoon, unless you are a furious antiquary, and wish to examine, one by one, all the old stones suspected of an inscription. The _Puerta de Triana_, also, has pretensions to Roman origin, and derives its name from the emperor Trajan. Its appearance is very stately; it is of the Doric order, with coupled columns, and is ornamented with the royal arms and surmounted by pyramids. It has its own alcade, and serves as a prison for gentlemen. The _Puertas del Carbon_ and _del Aceite_ are worthy of a visit. On the _Puerta de Jeres_ is the following inscription: Hercules me edifico, Julio Cesar me coesco, De Muros y torres altas El rey santo me gano Con Garci Perez de Vargas. Seville is surrounded by a continuous line of embattlemented walls, flanked at intervals by large towers, many of which are at present in ruins, and also by ditches, almost entirely choked up. These walls, which would not afford the least protection against modern artillery, produce, with their denticulated Arabic embrasures, a very picturesque effect. They are said to have been begun, like all other walls and camps that ever existed, by Julius Cæsar.
