exclamations of the excited multitude. On the elevated ground behind the circus is a fringe of olive-trees, with a line of feathery elms beyond; and rising over all, the purple background of the Sabine and Alban hills. It is a lonely enough spot now; and the gentle hand of spring clothes the naked walls with a perfect garden of wild flowers, and softens with the greenest and tenderest turf the spots trodden by the feet of so many thousands. In the immediate vicinity of the circus are extensive ruins, visible and prominent objects from the road, consisting of large fragments of walls and apses, dispersed among the vineyards and enclosures. By far the best-known monument on the Appian Way is the Tomb of Caecilia Metella. It is a conspicuous landmark in the wide waste, and catches the eye at a long distance from many points of view. It is as familiar a feature in paintings of the Campagna almost as the Claudian Aqueduct. This celebrity it owes to its immense size, its wonderful state of preservation, and above all to the genius of Lord Byron, who has made it the theme of some of the most elegant and touching stanzas in _Childe Harold_. Nothing can be finer than the appearance of this circular tower in the afternoon, when the red level light of sunset, striking full upon it, brings out the rich warm glow of its yellow travertine stones in striking relief against the monotonous green of the Campagna. It is built on a portion of rising ground caused by a current of lava which descended from the Alban volcano during some prehistoric eruption, and stopped short here, forming the quarries on the left side of the road which supply most of the paving-stone of modern Rome. The Appian Way was here lowered several feet below the original level, in order to diminish the acclivity; and the mausoleum was consequently raised upon a substructure of unequal height corresponding with the inclination of the plane of ascent. It was originally cased with marble slabs, but these were stripped off during the middle ages for making lime; and Pope Clement XII. completed the devastation by removing large blocks which formed the basement, in order to construct the picturesque fountain of Trevi. A large portion of the Doric marble frieze, however, still remains, on which are sculptured bas-reliefs of rams' heads, festooned with garlands of flowers. Usually the bas-reliefs are supposed to represent bulls' heads; and the name of Capo de Bove (the "head of the ox"), by which the monument has long been known to the common people, is said to be derived from these ornaments. But a careful examination will convince any one that they are in reality rams' heads; and the vulgar name of the tomb was obviously borrowed from the armorial bearings of the Gaetani family, consisting of an ox's head, affixed prominently upon it when it served them as a fortress in the thirteenth century. Pope Boniface VIII., a member of this family, added the curious battlements
