Question 69. Why, upon the festival called Septimontium, did they observe to abstain from the use of chariots drawn by a pair of horses; and even until now, do they that regard antiquity still abstain? They do observe the Septimontium feast in honor of the addition of the seventh hill to the city, upon which it became Septicollis, seven-hilled Rome. Solution. What if it be (as some of the Romans conjecture) because the parts of the city are not as yet everywhere connected? Or if this conceit be nothing to the purpose, what if it be that, when the great work of building the city was finished and they determined to cease the increasing of the city any further, they rested themselves and rested the cattle that bore a share in the labor with them, and provided accordingly that they might participate of the holiday by rest from labor? Or was it that they would have all the citizens always present for the solemnity and return of a festival, especially that which was observed in remembrance of the compact uniting the parts of the city; and that none should desert the city for whose sake the feast is kept, they were not allowed to use their yoke chariots that day?
