The most simple form of the ancient sepulchre was that of a square, or circular tower, of no great height or size, on a square basement. Fragments of white marble remain in sufficient quantity, to shew that a large proportion of the tombs must have been covered with this material, but for the most part, the existing ruins are merely indistinct masses of rubble. Some are of brick, but these are usually of greater extent, and more complicated forms, with domes and arches; and are probably of later date. These sepulchral chambers are disposed in a single line on each side of the Appian way, but a little further on, we find a great number of fragments scattered over a considerable extent, and called Roma Vecchia. There are about Rome several buildings more or less closely resembling what I have above described under the name of the temple of Rediculus. Many of these have evident traces of a portico of four columns: one of them has two orders in height, and there are other trifling differences; but in the whole, there is a striking similarity both of design and execution. The facing is uniformly of very neat brickwork, and they are probably all nearly of the same period. There are three such at this Roma Vecchia (for there is more than one Roma Vecchia); four more near the modern road to Naples, one of which has been christened the temple of Fortuna Muliebris, and two or three, out of the Porta San Lorenzo. Beyond Roma Vecchia we meet again with tombs, and with a farmhouse, most of the walls of which seem to be ancient. Near this there has been a magnificent pyramidal sepulchre, surrounded in its original state by arches, and probably by a colonnade. I extended my walk to an immense round mass, which has formed the basement of some spacious mausoleum; it was unfortunately locked up, nor could I find anybody in the little cottage with which it is at present crowned to give me entrance. Then leaving the Appian way, though marked still further by its line of tombs, and crossing the modern road to Albano and Naples, I found myself again among the ranges of those aqueducts, of which I have already given you some description. The Marana, or Acqua Crabra, here runs among them, conducted on the top of a small mound, and crossing in some places both lines of aqueducts. In Italy, the Roman roads do not by any means adhere to the direct straight line which characterizes them in England. Our country was a forest when these works were undertaken: Italy was highly cultivated, and divided into private estates, and this perhaps has in many cases given rise to the windings, both of the roads and aqueducts: indeed it is difficult to account for the abrupt turns of the latter on any other principle. By the sides of these aqueducts there are other ruins occupying a considerable extent, but no one of them announces any building of much importance. There are vaults, domes, and arches, and one of those great niches so common in the Roman ruins; where the whole
