Grimm, in his German Mythology, tells us: "It was often considered necessary to build living animals, even human beings, into the foundations on which any edifice was reared, as an oblation to the earth to induce her to bear the superincumbent weight it was proposed to lay upon her. By this horrible practice it was supposed that the stability of the structure was assured as well as other advantages gained." Of course the animal is merely the more modern substitute for the human being, just in the same manner as at the present day the bottle and coins are the substitute for the living animal. In Germany, after the burial of a living being under a foundation was given up, it became customary to place an empty coffin under the foundations of a house, and this custom lingered on in remote country districts until comparatively recent times. With the spread of Christianity the belief in human sacrifice died out. In 1885, Holsworthy Parish Church was restored; during the work of restoration it was necessary to take down the south-west angle of the wall, and in this wall was found, embedded in the mortar and stone, a skeleton. The wall of this part of the church had settled, and from the account given by the masons it would seem there was no trace of a tomb, but on the contrary every indication that the victim had actually been buried alive--a mass of mortar covered the mouth, and the stones around the body seemed to have been hastily built. Some few years ago the Bridge Gate of the Bremen city walls was taken down, and the skeleton of a child was found embedded in the foundations.[3] [Footnote 3: "Strange Survivals," Baring Gould.] The practice of our masons of putting the blood of oxen into mortar was no doubt in the first instance associated with the idea of a sacrifice; however this may be, the blood had no doubt a real effect in hardening the mortar, just the same as treacle, which has been known to be used in our days. The use of cement when any extra strength is needed has put aside the use of either blood or treacle in the mixing of mortar. It is a curious instance of the wide spread of the belief in blood as a cement for ancient buildings that Ala-ud-din Khilji, the King of Delhi, A.D. 1296-1315, when enlarging and strengthening the walls of old Delhi, is reported to have mingled in the mortar the bones and blood of thousands of goat-bearded Moghuls, whom he slaughtered for the purpose. A modern instance is furnished by advices which were brought from Accra, dated December 8th, 1881, that the King of Ashantee had murdered 200 girls, for the purpose of using their blood to mix with the mortar employed in the building of a new palace.
