Early symbol of Norway.  In the standardized Old Norse orthography, the name is spelled Níðhǫggr, but the letter ǫ is frequently replaced with the Modern Icelandic ö for reasons of familiarity or technical expediency. In Norse mythology, Níðhögg or Níðhöggr (Malice Striker) is a dragon/serpent who gnaws at a root of the world tree, Yggdrasil. In historical Viking society, níð was a term for a social stigma implying the loss of honor and the status of a villain. Thus, its name might refer to its role as a horrific monster in its action of chewing the corpses of the inhabitants of Náströnd: those guilty of murder, adultery, and oath-breaking, which Norse society considered among the worst possible.
