But the conception of the corn-spirit as embodied in pig form is nowhere more clearly expressed than in the Scandinavian custom of the Yule Boar. In Sweden and Denmark at Yule (Christmas) it is the custom to bake a loaf in the form of a boar-pig. This is called the Yule Boar. The corn of the last sheaf is often used to make it. All through Yule the Yule Boar stands on the table. Often it is kept till the sowing-time in spring, when part of it is mixed with the seed-corn and part given to the ploughmen and plough-horses or plough-oxen to eat, in the expectation of a good harvest.(123) In this custom the corn-spirit, immanent in the last sheaf, appears at midwinter in the form of a boar made from the corn of the last sheaf; and his quickening influence on the corn is shown by mixing part of the Yule Boar with the seed-corn, and giving part of it to the ploughman and his cattle to eat. Similarly we saw that the Corn-wolf makes his appearance at midwinter, the time when the year begins to verge towards spring.(124) We may conjecture that the Yule straw, of which Swedish peasants make various superstitious uses, comes, in part at least, from the sheaf out of which the Yule Boar is made. The Yule straw is long rye-straw, a portion of which is always set apart for this season. It is strewn over the floor at Christmas, and the peasants attribute many virtues to it. For example, they think that some of it scattered on the ground will make a barren field productive. Again, the peasant at Christmas seats himself on a log; his eldest son or daughter, or the mother herself, if the children are not old enough, places a wisp of the Yule straw on his knee. From this he draws out single straws, and throws them, one by one, up to the ceiling; and as many as lodge in the rafters, so many will be the sheaves of rye he will have to thresh at harvest.(125) Again, it is only the Yule straw which may be used in binding the fruit-trees as a charm to fertilise them.(126) These uses of the Yule straw show that it is believed to possess fertilising virtues analogous to those ascribed to the Yule Boar; the conjecture is therefore legitimate that the Yule straw is made from the same sheaf as the Yule Boar. Formerly a real boar was sacrificed at Christmas,(127) and apparently also a man in the character of the Yule Boar. This, at least, may perhaps be inferred from a Christmas custom still observed in Sweden. A man is wrapt up in a skin, and carries a wisp of straw in his mouth, so that the projecting straws look like the bristles of a boar. A knife is brought, and an old woman, with her face blackened, pretends to sacrifice the man.(128)
