down by word of mouth are generally of a far more archaic type than the religion depicted in the most ancient literature of the Aryan race.
It is on these grounds that, in discussing the meaning and origin of an ancient Italian priesthood, I have devoted so much attention to the popular customs and superstitions of modern Europe. In this part of my subject I have made great use of the works of the late W. Mannhardt, without which, indeed, my book could scarcely have been written. Fully recognising the truth of the principles which I have imperfectly stated, Mannhardt set himself systematically to collect, compare, and explain the living superstitions of the peasantry. Of this wide field the special department which he marked out for himself was the religion of the woodman and the farmer, in other words, the superstitious beliefs and rites connected with trees and cultivated plants. By oral inquiry, and by printed questions scattered broadcast over Europe, as well as by ransacking the literature of folk-lore, he collected a mass of evidence, part of which he published in a series of admirable works. But his health, always feeble, broke down before he could complete the comprehensive and really vast scheme which he had planned, and at his too early death much of his precious materials remained unpublished. His manuscripts are now deposited in the University Library at Berlin, and in the interest of the study to which he devoted his life it is greatly to be desired that they should be examined, and that such portions of them as he has not utilised in his books should be given to the world.
