The story of creation also impressed. It was enlightening and comprehensible. The parallel theory of spontaneous generation and the progressive evolution of the species which the magi entertained, they probably never heard. Even otherwise it was too complex for minds as yet untutored. The fables alone appealed. Mentally compressed into portable shape, carried along, handed down, their origin afterward forgotten, they became the traditions of a nation, which, eminently conservative, preserved what it found, among other things the name, perhaps inharmonious, of Jhvh.[31] [Footnote 31: Renan: Histoire du peuple d'Israel. Kuenen: De Godsdienst van Israel.] That name, since found on an inscription of Sargon, appears to have been the title of a local god of Sinai, whom the nomads may have identified with Elohim, particularly, perhaps, since he presided over thunder, the phenomenon that alarmed them most and which, in consequence, inspired the greatest awe. That awe they put into the name, the pronunciation of which, like the origin of their traditions, they afterward forgot. In subsequent rabbinical writings it became Shem, the Name; Shemhammephoresh, the Revealed Name, uttered but once a year, on the day of Atonement, by the high priest in the Holy of Holies. Mention of it by anyone else was deemed a capital offence, though, permissibly, it might be rendered El Shaddai, the Almighty. That term the Septuagint translated into [Greek: ho Kyrios], a Greek form, in the singular, of the Aramaic plural Adonai, which means Baalim, or sun lords. That form the Vulgate gave as Dominus and posterior theology as God. The latter term, common to all Teutonic tongues, has no known meaning. It designates that which, to the limited intelligence of man, has been, and must be, incomprehensible. But the original term Jhvh, which, in the seventeenth century, was developed into Jehovah, yet which, the vowels being wholly conjectural, might have been developed into anything else, clearly appealed to wayfarers to whom Chaldean science was a book that remained closed until Nebuchadnezzar blew their descendants back into the miraculous Babel of their youth. Meanwhile, apart from the name--now generally written Jahveh--apart too from the fables and the enduring detestation which the colossal city inspired, probably but one other thing impressed, and that was the observance of the Sabbath. To a people whose public works were executed by forced labour, such a day was a necessity. To vagrants it was not, and, though the custom interested, it was not adopted by them until their existence from nomad had become fixed.
