If, indeed, the earliest dwelling of man was a cave, rather than a tent, the household fire was still at its entrance; and the threshold was the hearthstone. When, in the progress of building-changes, the hearthstone was removed to the center of the building, or of the inner court, its sanctity went with it, as the place of the family fire. Thus, for example, in Russia, the Domovoi, or household deity, who is honored and invoked at the threshold, “is supposed to live behind the stove now, but in early times he, or the spirits of the dead ancestors, of whom he is now the chief representative, were held to be in even more direct relations with the fire on the hearth; as were the Penates of the Romans, who were sometimes spoken of as at the threshold, and again as at the hearth.”[57] A recognition of the peculiar sacredness of the threshold is shown, in different lands, by the popular unwillingness to have the dead carried over it on the way to burial. In India, the body of one dying in certain phases of the moon can in no wise be carried over the threshold. The house wall must be broken for its removal.[58] When Chinese students are attending the competitive examinations for promotion, they are shut up in rooms until their work is completed. If one of them dies at such a time, “the body is removed over the back wall, as the taking out openly through the front door would be regarded as an evil omen.”[59] In the capital of Korea there is a small gate in the city wall known as the “Gate of the Dead,” through which alone a dead body can be carried out. But no one can ever enter through that passage-way.[60] There is a recognition, in Russian folk-tales, of safety to the spirit of one who dies in a house, if his body be passed out _under_ the threshold of the outer door.[61] It is not allowable to carry out a corpse through the main door of a house in Italy. There is a smaller door, in the side wall, known as the _porta di morti_, which is kept closed except as it is opened for the removal of a body at the time of a funeral.[62] In Alaska, it is deemed an evil omen for the dead to be carried over the threshold. “Therefore the dying one, instead of being allowed to rest in peace in his last hours, is hastily lifted from his couch and put out of doors [or out of the house] by a hole in the rear wall” so as not to have a corpse pass the threshold.[63] In some communities, in both Europe and America, the coffin is passed out of the house through the window, instead of through the door, at a funeral. And again, the front door is closed and a window is opened at the time of a death, in order that the spirit may pass out of the house in some other way than over the threshold.[64]
