On May 23 the Senate meets in the Septa Julia--the ruins of which still exist, under the Palazzo Doria and the church of S. Maria in Via Lata--and passes two resolutions. Horace's hymn, vv. 17-20, alludes to the first: "O Goddess, whether you choose the title of Lucina or of Genitalis, multiply our offspring, and prosper the decree of the Senate in relation to the giving of women in wedlock, and the matrimonial laws." Among the penalties imposed on men and women who remained single between the ages of twenty and fifty years, was the prohibition against attending public festivities and ceremonies of state. The Senate, considering the extraordinary case of the _Ludi Sæculares_, which none among the living had seen or would ever see again, removes this prohibition. The second resolution provides for the erection of two commemorative pillars, one of bronze, the other of marble, upon which the official report of the celebration shall be engraved. The bronze pillar is probably lost forever, but the marble one is that recovered on the banks of the Tiber, September 20, 1890, the inscription on which I am endeavoring to explain.
The celebration in the strict sense of the word began at the second hour of the night of May 31. Sacrifices were offered to the Fates, on altars erected between the Tarentum and the banks of the Tiber, where S. Giovanni dei Fiorentini now stands; and the other ceremonies were performed on a wooden stage which was illuminated by lights and fires. This temporary theatre was not provided with seats, and the report calls it "a stage without a theatre." In the performances of the next day and in those of June 2 and 3, which took place on the Capitol and the Palatine, the following order was observed in the ceremonial pageant; first came Augustus as Emperor and Pontifex Maximus, next the Consuls, the Senate, the Quindecemviri and other colleges of priests, then followed the Vestal Virgins, and a group of one hundred and ten matrons (as many as there were years in the _sæculum_) selected from among the most exemplary _matres familiæ_ above twenty-five years of age.
Twenty-seven boys and twenty-seven girls of patrician descent whose parents were both living (_patrimi et matrimi_) were enlisted on June 3, to sing the hymn composed expressly by Horace. "Carmen composuit Q. Horatius Flaccus," so the report says (line 149). The first stanzas of the beautiful canticle were sung when the procession was marching from the Temple of Apollo to that of Jupiter Capitolinus, the middle portion on the Capitol, and the last on the way back to the Palatine. The accompaniments were played by the orchestra and the trumpeters of the official choir (_tibicines et fidicines qui sacris publicis præsto sunt_). The wealth of magnificence and beauty which the Romans beheld on the morning of June 3, 17 B. C., we can see as in a dream, but it baffles description. Imagine the group of fifty-four young patricians clad in snow-white tunics, crowned with flowers, and waving branches of laurel, led by Horace down the Vicus Apollinis (the street which led from the Summa Sacra Via to the house of Augustus on the Palatine), and the Sacra Via, singing the praises of the immortal gods:--
