Two excellent specimens of scholæ connected with Christian cemeteries and with meetings of the faithful have come down to us, one above the Catacombs of Callixtus, the other above those of Soter.
The first edifice has the shape of a square hall with three apses,—cella trichora. It is built over the part of the catacombs which was excavated at the time of Pope Fabianus (a. d. 236-250), who is known to have raised multas fabricas per cæmeteria; it is probably his work, as the style of masonry is exactly that of the first half of the third century. The original schola was covered by a wooden roof, and had no façade or door. In the year 258, while Sixtus II., attended by his deacons Felicissimus and Agapetus, was presiding over a meeting at this place in spite of the prohibition of Valerian, a body of men invaded the schola, murdered the bishop and his acolytes, and razed the building nearly to the level of the ground. Half a century later, in the time of Constantine, it was restored to its original shape, with the addition of a vaulted roof and a façade. The line which separates the old foundations of Fabianus from the restorations of the age of peace is clearly visible. Later the schola was changed into a church and dedicated to the memory of Syxtus, who had lost his wife there, and of Cæcilia, who was buried in the crypt below. It became a great place of pilgrimage, and the itineraries mention it as one of the leading stations on the Appian Way.
When de Rossi first visited the place, fifty years ago, this famous schola or church of Syxtus and Cæcilia was used as a wine-cellar, while the crypts of Cæcilia and Cornelius were used as vaults. Thanks to his initiative the monument has again become the property of the Church of Rome; and after a lapse of ten or twelve centuries divine service was resumed in it on the twentieth day of April of the present year. Its walls have been covered with inscriptions found in the adjoining cemetery.
The theory suggested by modern writers with regard to the scholæ is very much the same as that concerning the tablinum of private houses. At first the small building was sufficient to meet the wants of a small congregation; with the increase of the members it became a presbiterium, or place reserved for the bishop or the clergy, while the audience stood outside, under the shelter of a tent, or a roof supported by upright beams. Here also we have all the architectural elements of the Christian basilica.
PLAN OF SCHOLA ABOVE THE CATACOMBS OF CALLIXTUS
(From Nortet's Les Catacombes Romaines)
The name schola, in its original meaning, has never died out in Rome; and as in the Middle Ages we had the scholæ of the Saxons, the Greeks, the Frisians, and the Lombards, so we have in the present day those of the Jews (gli scoli degli ebrei).
III. Oratories and churches built over the tombs of martyrs and confessors. The sacred buildings of this class are, or were formerly, outside the walls, as burial was not allowed within city limits. To explain their origin and to understand their significance we must bear in mind the following rules. The action of the Roman law towards the Christians, that is, towards persons accused of atheism and rebellion against the Empire, resulted in the execution of those who were convicted. Except in extraordinary cases, the body of the victim could be claimed by relatives and friends and buried with due honors. In chapters vi. and vii. instances will be quoted of the erection of imposing tombs to the memory of Roman patricians, generals and magistrates, who were put to death under the imperial régime. The same privileges of burial were granted to the Christians, who preferred, however, the modesty and safety of a grave in the heart of the catacombs to the pompous luxury of a mausoleum above ground. The grave of a martyr was an object of consideration, and was often visited by pilgrims, who adorned it with wreaths and lights on the anniversary of his execution. After the end of the persecutions the first thought of the victorious church was to honor the memory of those who had fought so gallantly for the common cause, and who at the sacrifice of their lives had hastened the advent of the days of freedom and peace. No better altar than those graves could be chosen for the celebration of divine service; but they were sunk deep in the ground, and the cubicula of the catacombs were hardly capable of containing the officiating clergy, much less the multitudes of the faithful. Touching the graves, removing them to a more suitable place, was out of the question; in the eyes of the early Christians no more impious sacrilege could be perpetrated. There was but one way left to deal with the difficulty; that of cutting away the rock over and around the grave, and thereby gaining such space as was deemed sufficient for the erection of a basilica. The excavation was done in conformity with two rules,—that the tomb of the martyr should occupy the place of honor in the middle of the apse, and that the body of the church should be to the east of the tomb, except in cases of "force majeure," as when a river, a public road, or some other such obstacle made it necessary to vary this principle.
Such is the origin of the greatest sanctuaries of Christian Rome. The churches of S. Peter on the Via Cornelia, S. Paul on the Via Ostiensis, S. Sebastian on the Via Appia, S. Petronilla on the Via Ardeatina, S. Valentine on the Via Flaminia, S. Hermes on the Via Salaria, S. Agnes on the Via Nomentana, S. Lorenzo on the Via Tiburtina, and fifty other historical structures, owe their existence to the humble grave which no human hand was allowed to transfer to a more suitable and healthy place.
