Though the sacrificial victim had come to be regarded as an offering to the powers of blight, he may once have represented a divinity of growth or, in earlier times, the corn-spirit. Such a victim was slain at harvest, and harvest is often late in northern Celtic regions, while the slaying was sometimes connected not with the harvest field, but with the later threshing. This would bring it near the Samhain festival. The slaying of the corn-spirit was derived from the earlier slaying of a tree or vegetation-spirit embodied in a tree and also in a human or animal victim. The corn-spirit was embodied in the last sheaf cut as well as in an animal or human being.[909] This human victim may have been regarded as a king, since in late popular custom a mock king is chosen at winter festivals.[910] In other cases the effigy of a saint is hung up and carried round the different houses, part of the dress being left at each. The saint has probably succeeded to the traditional ritual of the divine victim.[911] The primitive period in which the corn-spirit was regarded as female, with a woman as her human representative, is also recalled in folk-custom. The last sheaf is called the Maiden or the Mother, while, as in Northamptonshire, girls choose a queen on S. Catharine's day, November 26th, and in some Christmas pageants "Yule's wife," as well as Yule, is present, corresponding to the May queen of the summer festival.[912] Men also masqueraded as women at the Calends. The dates of these survivals may be explained by that dislocation of the Samhain festival already pointed out. This view of the Samhain human sacrifices is supported by the Irish offerings to the Fomorians--gods of growth, later regarded as gods of blight, and to Cromm Cruaich, in both cases at Samhain.[913] With the evolution of religious thought, the slain victim came to be regarded as an offering to evil powers. This aspect of Samhain, as a festival to promote and assist festivity, is further seen in the belief in the increased activity of fairies at that time. In Ireland, fairies are connected with the Tuatha Dé Danann, the divinities of growth, and in many folk-tales they are associated with agricultural processes. The use of evergreens at Christmas is perhaps also connected with the carrying of them round the fields in older times, as an evidence that the life of nature was not extinct.[914]
