An edifice of the Doric order, called the Temple of Concord, has still its walls, its columns, entablature, and pediments, entire. In proceeding from the Temple of Concord, you walk between rows of sepulchres, cut in the rock, wherever it admitted of being excavated by the hand of man, or was so already by that of nature. Some masses are hewn into the shape of coffins; others drilled full of small square holes, employed in a different mode of interment, and serving as receptacles of urns. One ponderous piece of the rock lies in an extraordinary position. By the failure of its foundation, or the shock of an earthquake, it has been loosened from the general quarry, and rolled down the declivity, where it now remains supine, with the cavities turned upwards. There was also a temple dedicated to Ceres and Proserpine; with the ruins was formed a church, which now exists; and the road, leading to which, was cut out of the solid rock. In respect to the temple of Castor and Pollux, vegetation has covered the lower parts of the building, and only a few fragments of two columns appear between the vines. Of the Temple of Venus, about one half remains; but the glory of the place was the Temple of Jupiter Olympius, three hundred and forty feet long, sixty broad, and one hundred and twenty in height. Its columns and porticos were in the finest style of architecture; and its bas-reliefs and paintings executed with admirable taste. On its eastern walls was sculptured the Battle of the Giants; while the western represented the Trojan War; corresponding exactly with the description which Virgil had given of the painting in the Temple of Juno at Carthage. Diodorus Siculus extols the beauty of the columns which supported the building; the admirable structure of the porticos, and the exquisite taste with which the bas-reliefs and paintings were executed; but he adds, that the stately edifice was never finished. Cicero, against Verres, speaks of the statues he carried away. Mr. Swinburne says, that it has remaining not one stone upon another; and that it is barely possible, with the liberal aid of conjecture, to discover the traces of its plan and dimensions. He adds, however, that St. Peter's at Rome exceeds this celebrated temple more than doubly in every dimension; being two hundred and fifteen feet higher, three hundred and thirty-four longer, and four hundred and thirty-three wider. Added to these, there is now remaining a monument of Tero, king of Agrigentum, one of the first of the Sicilian tyrants. The great antiquity of this monument may be gathered from this; that Tero is not only mentioned by Diodorus, Polybius, and the more modern of the ancient historians, but likewise by Herodotus, and Pindar, who dedicates two of his Olympic Odes to him; so that this monument must be much more than two thousand years old. It is a kind of pyramid, the most durable of forms; and is surrounded by aged olive-trees, which cast a wild, irregular shade over the ruin.
