so, she must have become a goddess of mariners, for Nehellenia seems to be the Isis of the _interpretatio Romana_. As earth-goddess she comes naturally into relation with the dead, and like Odin is a leader of the rout of souls. In German peasant-lore she survives under various names, of which Perchta is the most important; in witch-lore, as Diana, and by a curious mediaeval identification, as Herodias[369]. And her more primitive functions are largely inherited by the Virgin, by St. Walpurg and by countless local saints. Most of the imaginative and mythological superstructure so briefly sketched in the last paragraph must be considered as subsequent in order of development to the typical village cult. Both before and in more fragmentary shape after the death of the old Keltic and Teutonic gods, that continued to be in great measure an amalgam of traditional rites of forgotten magical or pre-religious import. So far as the consciousness of the mediaeval or modern peasant directed it to unseen powers at all, which was but little, it was rather to some of these more local and bounded spirits who remained in the train of the gods, than to the gods themselves. For the purposes of the present discussion, it is sufficient to think of it quite generally as a cult of the spirits of fertilization, without attaching a very precise connotation to that term. Unlike the domestic cult of the ancestral ghosts, conducted for each household by the house-father at the hearth, it was communal in character. Whatever the tenure of land may have been, there seems no doubt that up to a late period ‘co-aration,’ or co-operative ploughing in open fields, remained the normal method of tillage, while the cattle of the community roamed in charge of a public herd over unenclosed pastures and forest lands[370]. The farm, as a self-sufficing agricultural unit, is a comparatively recent institution, the development of which has done much to render the village festivals obsolete. Originally the critical moments of the agricultural year were the same for the whole village, and the observances which they entailed were shared in by all.
