Much the most general opinion, however, was that some few escaped the desolating element by one of those means most familiar to the narrator, by ascending some mountain, on a raft or canoe, in a cave, or even by climbing a tree. No doubt some of these legends have been modified by Christian teachings; but many of them are so connected with local peculiarities and ancient religious ceremonies, that no unbiased student can assign them wholly to that source, as Professor Vater has done, even if the authorities for many of them were less trustworthy than they are. There are no more common heirlooms in the traditional lore of the red race. Nearly every old author quotes one or more of them. They present great uniformity of outline, and rather than engage in repetitions of little interest, they can be more profitably studied in the aggregate than in detail. By far the greater number represent the last destruction of the world to have been by water. A few, however, the Takahlis of the North Pacific coast, the Yurucares of the Bolivian Cordilleras, and the Mbocobi of Paraguay, attribute it to a general conflagration which swept over the earth, consuming every living thing except a few who took refuge in a deep cave.[202-1] The more common opinion of a submersion gave rise to those traditions of a universal flood so frequently recorded by travellers, and supposed by many to be reminiscences of that of Noah. There are, indeed, some points of striking similarity between the deluge myths of Asia and America. It has been called a peculiarity of the latter that in them the person saved is always the first man. This, though not without exception, is certainly the general rule. But these first men were usually the highest deities known to their nations, the only creators of the world, and the guardians of the race.[202-2] Moreover, in the oldest Sanscrit legend of the flood in the Zatapatha Brahmana, Manu is also the first man, and by his own efforts creates offspring.[202-3] A later Sanscrit work assigns to Manu the seven Richis or shining ones as companions. Seven was also the number of persons in the ark of Noah. Curiously enough one Mexican and one early Peruvian myth give out exactly seven individuals as saved in their floods.[203-1] This coincidence arises from the mystic powers attached to the number seven, derived from its frequent occurrence in astrology. Proof of this appears by comparing the later and the older versions of this myth, either in the book of Genesis, where the latter is distinguished by the use of the word Elohim for Jehovah,[203-2] or the Sanscrit account in the Zatapatha Brahmana with those in the later Puranas.[203-3] In both instances the number seven hardly or at all occurs in the oldest version, while it is constantly repeated in those of later dates.
