At this point I wish to notice one or two results of the adoption of a religious calendar such as I have been describing, which are more to the purpose of these lectures than some of the details I have had to point out. First, let us remember that agricultural operations necessarily vary in date according to the season, and that most of the rural festivals of ancient Italy were not fixed to a particular day, but were _feriae conceptivae_, settled perhaps according to the decision of some meeting of heads of families or officers of a pagus. That this was so we may conjecture from the fact that those which survived into historical times, _e.g._ Compitalia and Paganalia, and were celebrated in the city, though not as _sacra pro populo_,[204] were of varying date. But all the festivals of the calendar were necessarily fixed, and the days on which they were held were made over to the gods. Now by being thus fixed they would soon begin to get out of relation to agricultural life; just as, if the harvest festivals of our churches were fixed to one day throughout the country, the meaning of the religious service would sooner or later begin to lose something of its force. And how much the more would this be so if the calendar itself, from ignorance or mismanagement, began to get out of relation with the true season, as in course of time was frequently the case? When once under such circumstances the meaning of a religious rite is lost, where is its psychological efficacy? In the life of the old Latin farmer, as we saw, his religion was a reality, an organic growth, coincident at every point with the perils he encountered in his daily toil; here, in the City-state, it must from the beginning have had a tendency to become an unreality, and it ended by becoming one entirely. Some of the old rites may have attached new meanings to themselves; it is possible, for example, that beneath the military rites of March there was an original agricultural significance; the Saturnalia became a merry mid-winter festival for a town population. But a great number wholly lost meaning, and were so forgotten or neglected in course of time that even learned men like Varro do not seem to have been able to explain them. The only practical question about them for the later Romans was whether their days were _dies fasti_ or _nefasti_ or _comitiales_,--what work might or might not be done on them.
