The scientific study of primitive religion is still almost in its infancy, and a large amount of conjecture must necessarily enter into any explanations of popular ritual that can be offered. In attempting to account for Christmas customs we must be mindful, therefore, of the tentative nature of the theories put forward. Again, it is important to remember that ritual practices are far more enduring than the explanations given to them. "The antique religions," to quote the words of Robertson Smith, "had for the most part no creed; they consisted entirely of institutions and practices ... as a rule we find that while the practice was |165| rigorously fixed, the meaning attached to it was extremely vague, and the same rite was explained by different people in different ways."{7} Thus if we can arrive at the significance of a rite at a given period, it by no means follows that those who began it meant the same thing. At the time of the conflict of the heathen religions with Christianity elaborate structures of mythology had grown up around their traditional ceremonial, assigning to it meanings that had often little to do with its original purpose. Often, too, when the purpose was changed, new ceremonies were added, so that a rite may look very unlike what it was at first. With these cautions and reservations we must now try to trace the connection between present-day or recent goings-on about Christmas-time and the festival practices of pre-Christian Europe. * * * * * Christmas, as we saw in Chapter I., has taken the date of the _Natalis Invicti_. We need not linger over this feast, for it was not attended by folk-customs, and there is nothing to connect it with modern survivals. The Roman festivals that really count for our present purpose are the Kalends of January and, probably, the _Saturnalia_. The influence of the Kalends is strongest naturally in the Latin countries, but is found also all over Europe. The influence of the _Saturnalia_ is less certain; the festival is not mentioned in ecclesiastical condemnations after the institution of Christmas, and possibly its popularity was not so widespread as that of the Kalends. There are, however, some curiously interesting Christmas parallels to its usages.
