No. 48: Nov-Dec 1986
It is safe to say that the great majority of professional archeologists consider the Kensington Stone, with its runic inscription, to be a hoax. E. Wahlgren's 1958 book bears the title: The Kensington Stone: A Mystery Solved. This title reflects the professional attitude, although not the disdain, even contempt, with which academics now view this controversial artifact.
Two major challenges to the authenticity of the Kensington Stone are:
(1) Its use of Arabic number placement: that is, decimal placement, and (2) Its use of the symbol for 10.
Professional archeologists and epigraphers maintain that genuine runic inscriptions did not use these Arabic innovations.
In the present article, R. Nielsen, University of Denmark, demonstrates with actual, well-established runic inscriptions that the above criticisms are without foundation. Such notation and convention were employed. In fact, the use of Arabic innovations actually supports the authenticity of the Kensington Stone.
