We have already had occasion to observe that the Mosaic narrative,--that first monument of all history, (which a very intellectual German writer has called the primitive document of the human race, and which it indeed is even in a mere historical sense, and in the literal acceptation of the word,) that the Mosaic narrative, we say, ascribes to the Cainites the origin of hereditary arts and trades. And there are two which are particularly worthy of remark, and to which I drew your attention--the knowledge of metals, and the art of music. I used the general expression, the knowledge of metals, because in the primitive ages of the world, the art of working mines, or of exploring and extracting metals from the earth, was essentially connected with the art of preparing and polishing them; and this knowledge of metals was very instrumental in forwarding the infant civilization of the primitive world, as the art of working and polishing them has ever contributed to the refinement of mankind. By the music of the Cainites, I said we were not to understand our own more elaborate and sublime system of melody. This art was chiefly consecrated in those ancient times, to the uses of divine service; still older, perhaps, was the medicinal, or rather the magical, use and influence of music. This is at least indicated by the tradition and mythology of all nations; and such a supposition is quite conformable to the spirit of those early ages; and I would here remind you that, in the primitive symbolical writing of the Chinese, the sign of a magician represents also a priest--a character which, as Remusat has observed, is not to be found in the narrow circle of their symbols. I added, that the existence of an hereditary caste of warriors among the Cainites was possible, and even probable; though not so, in my opinion, the existence of an hereditary sacerdotal caste. But though such an institution did not emanate from the Cainites, it may at least have been occasioned by them. As I said before, the Mosaic history represents the vast, boundless, prodigious corruption of the world in the age immediately preceding the deluge, as produced solely by the union of the better and godly portion of mankind with the lawless descendants of Cain. Thus this would supposes a certain dread and apprehension of any alliance and intercourse with a race laden with malediction, and pregnant with calamity. And may not this very circumstance have given rise to the establishment of a distinctly separate and hereditary class, not of priests in the later signification of that word, but of men chosen and consecrated by God, and entirely devoted to his service? and, consequently, is it not among the later Sethites, we must look for the origin of this institution?
