It was celebrated, in commemoration of a victory obtained over the Latians, the news of which was said to have been brought by Castor and Pollux, in person. This festival, was, at first, consecrated to Jupiter, Juno, and Minerva. But it was afterwards made more general, and celebrated in honor of all the Gods. This procession was in the month of September. It began at the temple of _Jupiter Capitolinus_, proceeded to the _Forum Romanum_, from thence to the _Velabrum_, and afterwards to the _Grand Circus_. You have in Onuphrius Panvinius, the order of this procession at large, of which the directors were the chief magistrates of the city: the sons of the nobility leading the van. Those of the Equestrian order, whose fathers were worth a hundred and fifty thousand sesterces, followed on horseback. It would be here foreign from my purpose to give the whole description of this procession, and of those who composed it. It is sufficient to observe, that processional dancing constituted a considerable part of it. The Pirrhic dance, executed to a martial air, called the _Proceleumaticus_, employed the men of arms. These were followed by persons who danced and leaped, in the manner of Satirs, some of them in the dress ascribed to _Silenus_, attended by performers on instruments adapted to that character of dance. These made the comic part of the procession, and the persons representing Satirs, took care to divert the people by leaps, by a display of agility, and by odd uncouth attitudes, such as were in the character they had assumed. There were also in another part of the procession twelve _Salii_, or priests of Mars, so called from their making sacred dances in honor of that God, the most considerable part of their worship; these were headed by their master or _Præsul_, the leader of the dance, a term afterwards assumed by the Christian Prelates. There were also the _Salian_ virgins, besides another division of the _Salii_ called _Agonenses_ or _Collini_. Nor is the processional dancing any thing surprizing; concerning that among the heathens, and even among the Hebrews, they were greatly in use. Who does not know that David's dancing before the arch was but in consequence of its being one of the religious ceremonies on that occasion?
