René Salm has translated the first two chapters of a fascinating study by Ditlef Nielsen, The Old Arabian Moon Religion And The Mosaic Tradition (1904) and made them available online at his Mythicist Papers resource page.
He has other resources there, too. Anyone interested in the origins of the “Nazarene” epithet [n-ts-r] applied to Jesus and early Christians, in the roots of the three-day death and resurrection concept in myth, of the (very early) background to what the later emergence of the Mandean or John the Baptist sect, the astrological basis for the Jewish sabbath and “magical” numbers, will find these resources indispensable. I have just completed the second chapter of Nielsen’s book and found it absolutely fascinating.
