I lifted out those letters which are Roman numerals, except from the second D, which cannot apear after DC, and the D in the second word, and formed: + NORWHDGH ROD - DCXXXVI + Norwedge Rod or Norwegian Cross, corresponding to the two Norwegian crosses on the right and left.The old word rod is the symbol of power, as in Revelations 2:27 "He will rule the nations with an iron rod." And cross, a synonym for rod, is also a means of execution. This means my explanation is that the sword states its identity: Norwedge Rod. DCXXXVI then refers to the year 636.
