Heimskringla Originated Skills

When Óðinn of the Æsir came to the northern lands, and the gods with him,
it is truthfully said that they originated and taught those skills that people
went on practising long afterwards. Óðinn was superior to them all, and from
him they learned all skills, because he knew them all first, and yet more.
But there is this to be said about why he was so very exalted—there were
these reasons for it: he was so fair and noble in countenance, when he was
sitting among his friends, that it rejoiced the hearts of all.
