The hobby-horse is an example of an apparently grotesque element which is found widespread in folk-processions, and which a previous chapter has traced to its ritual origin. The man clad in a beast-skin is the worshipper putting himself by personal contact under the influence and protection of the sacrificed god. The rite is not a very salient one in modern winter processions, although it has its examples, but its historical importance is great. A glance at the ecclesiastical denunciations of the Kalends collected in an appendix will disclose numerous references to it. These are co-extensive with the western area of the Kalends celebrations. In Italy, in Gaul, in southern Germany, apparently also in Spain and in England, men decked themselves for riot in the heads and skins of cattle and the beasts of the chase, blackened their faces or bedaubed them with filth, or wore masks fit to terrify the demons themselves. The accounts of these proceedings are naturally allusive rather than descriptive; the fullest are given by a certain Severian, whose locality and date are unknown, but who may be conjectured to speak for Italy, by Maximus of Turin and Chrysologus of Ravenna in the fifth century, and by Caesarius of Arles in the beginning of the sixth. Amongst the _portenta_ denounced is a certain _cervulus_, which lingers in the _Penitentials_ right up to the tenth century, and with which are sometimes associated a _vitula_ or _iuvenca_. Caesarius adds a _hinnicula_, and St. Eadhelm, who is my only authority for the presence of the _cervulus_ in England, an _ermulus_. These seem to be precisely of the nature of ‘hobby-horses.’ Men are said _cervulum ambulare_, _cervulum facere_, _in cervulo vadere_, and Christians are forbidden to allow these _portenta_ to come before their houses. The _Penitential_ of the Pseudo-Theodore tells us that the performers were those who wore the skins and heads of beasts. Maximus of Turin, and several writers after him, put the objection to the beast-mimicry of the Kalends largely on the ground that man made in the image of God must not transform himself into the image of a beast. But it is clear that the real reason for condemning it was its unforgettable connexion with heathen cult. Caesarius warns the culprit that he is making himself into a _sacrificium daemonum_, and the disguised reveller is more than once spoken of as a living image of the heathen god or demon itself. There is some confusion of thought here, and it must be remembered that the initial significance of the skin-wearing rite was probably buried in oblivion, both for those who practised it and for those who reprobated. But it is obvious that the worshipper wearing a sacrificial skin would bear a close resemblance to the theriomorphic or semi-theriomorphic image developed out of the sacrificial skin nailed on a tree-trunk; and it is impossible not to connect the fact that in the prohibitions a
