But this reckoning of the year, if it ever existed at all, could not have lasted long as it stood. As we know it in historical times, it has become modified by applying to it the principle of the solar year. The reason for this should be noted carefully. A lunar year, being about 11 days short of the solar year, would in a very short time become out of harmony with the seasons. Now if there is one thing certain about the Roman religious calendar, it is that many at least of its oldest festivals mark those operations of husbandry on which the population depended for its subsistence, and for the prosperous result of which divine agencies must be propitiated. These festivals, when fixed in the calendar, must of course occur at the right seasons, which could not be the case if the calendar were that of a purely lunar year. It was therefore necessary to work in the solar principle; and this was done[6] by a somewhat rude expedient, not unlike that of the Athenian Octaeteris, and probably derived from it[7]. A cycle of 4 years was devised, of which the first had the 355 days of the lunar year, the second 355 + 22, the third 355 again, and the fourth 355 + 23. The extra periods of 22 and 23 days were inserted in February, not at the end, but after the 23rd (Terminalia)[8]. The total number of days in the cycle was 1465, or about 1 day too much in each year; and in course of time even this system got out of harmony with the seasons and had to be rectified from time to time by the Pontifices, who had charge of the calendar. Owing to ignorance on their part, misuse or neglect of intercalation had put the whole system out of gear before the last century of the Republic. All relation to sun and moon was lost; the calendar, as Mommsen says, ‘went on its own way tolerably unconcerned about moon and sun.’ When Caesar took the reform of the calendar in hand the discrepancy between it and the seasons was very serious; the former being in advance of the latter probably by some weeks. Caesar, aided by the mathematician Sosigenes, put an end to this confusion by extending the year 46 B.C. to 445 days, and starting afresh on Jan. 1, 45 B.C.[9]—a day henceforward to be that of the new year—with a cycle of 4 years of 365 days[10]; in the last of which a single day was added, after the Terminalia. This cycle produced a true solar year with a slight adjustment at short intervals; and after a few preliminary blunders on the part of the Pontifices, lasted without change until A.D. 1582, when Pope Gregory XIII set right a slight discrepancy by a fresh regulation. This regulation was only adopted in England in 1752, and is still rejected in Russia and by the Greek Church generally.
II. Order of Months in the Year.
That the Roman year originally began with March is certain[11], not only from the evidence of the names of the months, which after June are reckoned as 5th (Quinctilis), 6th (Sextilis), and so on, but from the nature of the March festivals, as will be shown in treating of that month. In the character of the religious festivals there is a distinct break between February and March, and the operations both of nature and of man take a fresh turn at that point. Between the festivals of December and those of January there is no such break. No doubt January 1, just after the winter solstice, was even at an early time considered in some sense as a beginning; but it is going too far to assume, as some have done, that an ancient religious or priestly year began at that point[12]. It was not on January 1, but on March 1, that the sacred fire in the Aedes Vestae was renewed and fresh laurels fixed up on the Regia, the two buildings which were the central points of the oldest Roman religion[13]. March 1, which in later times at least was considered the birthday of the special protecting deity of the Romans, continued to be the Roman New Year’s Day long after the official beginning of the year had been changed to January 1[14]. It was probably not till 153 B.C., when the consuls began to enter on office on January 1, that this official change took place; and the date was then adopted, not so much for religious reasons as because it was convenient, when the business of administration was increasing, to have the consuls in Rome for some time before they left for their provinces at the opening of the war season in March.
No rational account can in my opinion be given of the Roman religious calendar of the Republic unless it be taken as beginning with March; and in this work I have therefore restored the old order of months. With the Julian calendar I am not concerned; though it is unfortunate that all the Roman calendars we possess, including the Fasti of Ovid, date from after the Julian era, and therefore present us with a distorted view of the true course of the old Roman worship.
Next after March came Aprilis, the month of opening or unfolding vegetation; then Maius, the month of growing, and Junius, that of ripening and perfecting. After this the names cease to be descriptive of the operations of nature; the six months that follow were called, as four of them still are, only by their positions relative to March, on which the whole system of the year thus turned as on a pivot.
The last two months of the twelve were January and February. They stand alone among the later months in bearing names instead of mere numbers, and this is sufficient to suggest their religious importance. That they were not mere appendages to a year of ten months is almost certain from the antique character of the rites and festivals which occur in them—Agonia, Carmentalia, Lupercalia, &c.; and it is safer to consider them as marking an ancient period of religious importance preparatory to the beginning of the year, and itself coinciding with the opening of the natural year after the winter solstice. This latter point seems to be indicated in the name Januarius, which, whether derived from janua, ‘a gate,’ or Janus, ‘the god of entrances,’ is appropriate to the first lengthening of the days, or the entrance of the sun on a new course; while February, the month of purifying or regenerative agencies (februa), was, like the Lent of the Christian calendar, the period in which the living were made ready for the civil and religious work of the coming year, and in which also the yearly duties to the dead were paid.
It is as well here to refer to a passage of Ovid (Fasti, ii. 47 foll.), itself probably based on a statement of Varro, which has led to a controversy about the relative position of these two months:
Sed tamen antiqui ne nescius ordinis erres,
Primus, ut est, Iani mensis et ante fuit.
Qui sequitur Ianum, veteris fuit ultimus anni,
Tu quoque sacrorum, Termine, finis eras.
Primus enim Iani mensis, quia ianua prima est;
Qui sacer est imis manibus, imus erat.
Postmodo creduntur spatio distantia longo
Tempora bis quini continuasse viri.
This plainly means that from the time when March ceased to be the first month, the year always began with January and ended with February; in other words the order was January, March, April, and so on, ending with February; until the time of the Decemvirate, when February became the second month, and December the last, as at present, January still retaining its place. A little consideration of Ovid’s lines will, however, suggest the conclusion that he,
