THE ARA DITIS ET PROSERPINÆ. On the 20th of September, 1890, the workmen employed in the construction of the main sewer on the left bank of the Tiber, between the Ponte S. Angelo and the church of S. Giovanni dei Fiorentini, found a mediæval wall, built of materials collected at random from the neighboring ruins. Among them were fragments of one or more inscriptions which described the celebrations of the _Ludi Sæculares_ under the Empire. By the end of the day, seventeen pieces had been recovered, seven of which belonged to the records of the games celebrated under Augustus, in the year 17 B. C., the others to those celebrated under Septimius Severus and Caracalla, in the year 204 A. D. Later researches led to the discovery of ninety-six other fragments, making a total of one hundred and thirteen, of which eight are of the time of Augustus, two of the time of Domitian, and the rest date from Severus.

The fragments of the year 17 B. C., fitted together, make a block three metres high, containing one hundred and sixty-eight minutely inscribed lines. This monument, now exhibited in the Baths of Diocletian, was in the form of a square pillar enclosed by a projecting frame, with base and capital of the Tuscan order, and it measured, when entire, four metres in height. I believe that there is no inscription among the thirty thousand collected in volume vi. of the "Corpus" which makes a more profound impression on the mind, or appeals more to the imagination than this official report of a state ceremony which took place over nineteen hundred years ago, and was attended by the most illustrious men of the age.
The origin of the sæcular games seems to be this: In the early days of Rome the northwest section of the Campus Martius, bordering on the Tiber, was conspicuous for traces of volcanic activity. There was a pool here called Tarentum or Terentum, fed by hot sulphur springs, the efficiency of which is attested by the cure of Volesus, the Sabine, and his family, described by Valerius Maximus. Heavy vapors hung over the springs, and tongues of flame were seen issuing from the cracks of the earth. The locality became known by the name of the fiery field (_campus ignifer_), and its relationship with the infernal realms was soon an established fact in folk-lore. An altar to the infernal gods was erected on the borders of the pool, and games were held periodically in honor of Dis and Proserpina, the victims being a black bull and a black cow. Tradition attributed this arrangement of time and ceremony to Volesus himself, who, grateful for the recovery of his three children, offered sacrifices to Dis and Proserpina, spread _lectisternia_, or reclining couches, for the gods, with tables and viands before them, and celebrated games for three nights, one for each child which had been restored to health. In the republican epoch they were called _Ludi Tarentini_, from the name of the pool, and were celebrated for the purpose of averting from the state the recurrence of some great calamity by which it had been afflicted. These calamities being contingencies which no man could foresee, it is evident that the celebration of the _Ludi Tarentini_ was in no way connected with definite cycles of time, such as the _sæculum_.
