Rígsþula
Rígsþula or Rígsmál (Old Norse: 'The Lay of Ríg') is an Eddic poem, preserved in the Codex Wormianus (AM 242 fol), in which a Norse god named Ríg or Rígr, described as "old, wise, mighty and strong", fathers the social classes of mankind. The prose introduction states that Rígr is another name for Heimdall, who is also called the father of mankind in Völuspá.
