fact that there is, strictly speaking, no connection between the two. The controversy has been resumed lately by Professor Luigi Pigorini in a paper still unpublished which was read at the sitting of the German Institute, December 17, 1890; and by Professor Otto Richter in his pamphlet Die älteste Wohnstätte des römischen Volks, Berlin, 1891.
In view of the ignorance of ancient writers on this subject, and the almost absurd definitions they give of the word, we had come to the conclusion that the altar had been removed or concealed by Augustus, when he built the Temple of Apollo and the Portico of the Danaids, in 28 b. c. A remarkable inscription discovered September 20, 1890 (to which I shall refer at length later), by mentioning the Roma Quadrata as existing a. d. 204, shows that our opinion was wrong, and that the old altar, the most venerable monument of Roman history, had survived the vicissitudes of time, and the transformation of the Palatine from the cradle of the city into the palace of the Cæsars.
In December, 1869, when the nuns of the Visitation were laying the foundations of a new wing of their convent on the area of the Temple of Apollo,44 I saw a line of square pilasters at the depth of forty-one feet below the pavement of the Portico of the Danaids, and in the centre of the line a heap of stones, either of tufa or peperino, roughly squared. It is more than probable that, in 1869, I did not think of the Roma Quadrata, and of its connection with those remains, so deeply buried in the heart of the hill; but I am sure that a careful investigation of that sacred spot would lead to very important results.
Ara of Aius Locutius on the Palatine.
The Ara of Aius Locutius. In 1820, while excavations were proceeding near the western corner of the Palatine (at the spot marked No. 7, on the plan, page 106, of "Ancient Rome"), an altar was discovered, of archaic type, inscribed with the following dedication: "Sacred to a Divinity, whether male or female. Caius Sextius Calvinus, son of Caius, praetor, has restored this altar by decree of the Senate." Nibby and Mommsen believe Calvinus to be the magistrate mentioned twice by Cicero as a candidate against Glaucias in the contest for the praetorship of 125 b. c. They also identify the altar as (a restoration of) the one raised behind the Temple of Vesta, in the "lower New Street," in memory of the mysterious voice announcing the invasion of the Gauls, in the stillness of the night, and warning the citizens to strengthen the walls of their city. The voice was attributed to a local Genius, whom the people named Aius Loquens or Locutius. As a rule, the priests refrained from mentioning in public prayers the name and sex of new and slightly known divinities, especially of local Genii, to which they objected for two reasons: first, because there was danger of vitiating the ceremony by a false invocation; secondly, because it was prudent not to reveal the true name of these tutelary gods to the enemy of the commonwealth, lest in case of war or siege he could force them to abandon the defence of that special place, by mysterious and violent rites. The formula si deus si dea, "whether god or goddess," is a consequence of this superstition; its use is not uncommon on ancient altars; Servius describes a shield dedicated on the Capitol to the Genius of Rome, with the inscription: GENIO URBIS ROMÆ SIVE MAS SIVE FEMINA, "to the tutelary Genius of the city of Rome, whether masculine or feminine." The Palatine altar, of which I give an illustration, cannot fail to impress the student, on account of its connection with one of the leading events in history, the capture and burning of Rome by the Gauls, 390 b. c.
Pillar commemorating the Ludi Sæculares.
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.
Not long after Augustus had assumed the supreme power, the Quindecemviri sacris faciundis (a college of priests to whom the direction of these games had been intrusted from time immemorial) announced that it was the will of the gods that the Ludi Sæculares should be performed, and misrepresenting and distorting events and dates, tried to prove that the festival had been held regularly at intervals of 110 years, which was supposed to be the length of a sæculum. The games of which the Quindecemviri made this assertion were the Tarentini, instituted for quite a different purpose, but their suggestion was too pleasing to Augustus and the people to be despised. Setting aside all disputes about chronology and tradition, the celebration was appointed for the summer of the year 17 b. c.
Plan and section of the Altar of Dis and Proserpina.
What was the exact location of the sulphur springs, the Tarentum, and the altar of the infernal gods? I have reason to regard the discovery of the Altar of Dis and Proserpina as the most satisfactory I have made, especially because I made it, if I may so express myself, when away from Rome on a long leave of absence. It took place in the winter of 1886-87, during my visit to America. At that time the work of opening and draining the Corso Vittorio Emanuele had just reached a place which was considered terra incognita by the topographers, and indicated by a blank spot in the archæological maps of the city. I mean the district between the Vallicella (la Chiesa Nuova, the Palazzo Cesarini, etc.) and the banks of the Tiber near S. Giovanni dei Fiorentini. The reports spoke vaguely about the discovery of five or six parallel walls, built of blocks of peperino, of marble steps in the centre of this singular monument, of gates with marble posts and architraves, leading to the spaces between the six parallel walls, and finally, of a column with foliage carved upon
