Conspicuous among these burial-places is the tomb which remained in possession of the great family of the Cornelian Scipios for nearly four centuries.[118] The entrance to this is near the gate of one of the vineyards, on the north-east side of the Appian Road, about two hundred and fifty yards from the Porta S. Sebastiano. The tomb itself consists of a number of passages roughly hewn in the tufa stone, as the catacombs are, without any apparent plan of arrangement. Unfortunately, the original state of the catacomb has been so altered by the substructions which have been found necessary to support the roof that it can hardly be recognised at the present day, and the sarcophagi and inscriptions have been removed, and placed for greater security in the Vatican Museum. Those now seen in situ are modern copies. Anciently there were two entrances, one from the Via Appia, and the other from the road which here unites the Via Appia and Via Latina. The present entrance has been cut for the convenience of access from the Appian Road.
Columbaria.
The catacomb of the Scipios differs from most of the other burial places which surround it, on account of the retention by the gens Cornelia of the old Latin custom of burying in coffins, instead of burning the corpse of the deceased. Most of the burying places on the Monte d’Oro are arranged in the manner called a columbarium by the Romans, from the resemblance of the niches in it to the holes in a pigeon-house.[119] Four of these columbaria have been excavated in the Vigna Codini, near the Porta S. Sebastiano, and are now to be seen in almost perfect preservation. They consist of a square pit roofed over, and entered by a staircase. The roof is supported by a massive square central column, and the whole of the sides of the pit and of the central column are pierced with semicircular niches, containing earthenware jars filled with ashes. In one of the columbaria in the Vigna Codini there is room for 900 jars. Most of the names which are inscribed above each niche upon a marble tablet are those of imperial freedmen, or servants of great families or public officers, and other persons of the middle class of life, and are therefore of little historical interest. The ashes of some few of a somewhat higher grade, are placed in small marble sarcophagi or urns, but no persons of distinguished rank appear to have been buried in this way. There are, however, few places in Rome where the ordinary manners and customs of the ancient Romans are more vividly placed before the eye than here, and the very insignificance of some of the details exhibited is somewhat striking. In one corner we find the ashes of a lady’s maid attached to one of the imperial princesses; in another, those of the royal barber; and in another, a favourite lapdog has been admitted to take his place among his mistress’s other faithful servants.
Arch of Drusus.
Not far from these columbaria, and close to the Porta S. Sebastiano, the Via Appia is spanned by a half ruinous archway, of which little but the core remains, the marble casing having long been torn off. It was probably originally ornamented with eight columns, two only of which now remain standing on the side next the modern gateway. These have shafts of Numidian marble (giallo antico), and composite capitals with Corinthian bases.
Upon the top of this arch is a brick ruin apparently belonging to the Middle Ages, as the style of building is similar to that called opera saracenica by the Italians. It was probably a part of a fortified tower, placed upon the arch, resembling that which formerly surmounted the Arch of Titus.
On each side of the arch are some remains of the branch aqueduct, which brought water from the Aqua Marcia to the Baths of Caracalla, and it is natural to conclude that this arch carried the aqueduct over the Via Appia, and was built by Caracalla for that purpose. The costly nature of the materials used has, however, induced most topographers to reject this explanation, and to assume that the arch is one of the three mentioned by the Notitia in the first region, as built in honour respectively of Drusus, Trajan, and Verus. The composite capitals seem to point to the earliest date of these three, and as the building bears a resemblance to a representation of the Arch of Drusus, which has been discovered upon a coin,[120] the arch has been thought identical with that erected to Drusus, the father of Claudius, mentioned by Suetonius.
Sessorium and Amphitheatrum Castrense.
Two ruins standing near the Basilica of S. Croce in Gerusalemme may be reckoned as belonging to the district of the Cælian Hill They are called by the topographers the Sessorium and the Amphitheatrum Castrense. The first of these consists of a ruin built of brick, containing a large semicircular apse with round-headed windows, from which two walls project. No excavations having been made in order to ascertain the further extent of the buildings, any opinion formed as to their purpose must necessarily be highly uncertain. The most probable conjecture which has been made is that they are the ruins of a tribunal called the Sessorium. Such a court of justice is mentioned by the Scholiast on Horace as situated on the Esquiline near the place where criminals and paupers were buried. Further notices of the same name as applied to an edifice in the neighbourhood of the Basilica of S. Croce are to be found in Anastasius’s Life of S. Silvester, and in a fragmentary history of certain passages in the Life of Theodoric, printed at the end of the work of Ammianus Marcellinus. Theodoric is there said to have ordered a criminal to be beheaded in palatio quod appellatur Sessorium, using the same phrase which Anastasius also employs.
The authors of the Beschreibung Roms supposed that this ruin was the Nymphæum Alexandri of the Notitia, but this has been disproved by Becker, who shows that the Nymphæum was near the Villa Altieri.
