) "the Mountain-High" Olafsson
was a petty king of Vestfold
in what is today Norway
. He was the son of Olaf Geirstad-Alf
, a cousin of Harald Fairhair
and the father of Aseda (or Ascrida) Rognvaldsdatter, who married Eystein Ivarsson
His greatest contribution to posterity was that he asked the skald Þjóðólfr of Hvinir to compose a poem about his ancestry. This poem is known as Ynglingatal and is not only one of the oldest, but also one of the most famous and debated of the Old Norse poems.
Þjóðólfr ended the poem with these lines:
- Under the heaven's blue dome, a name
- I never knew more true to fame
- Than Rognvald bore; whose skilful hand
- Could tame the scorners of the land, --
- Rognvald, who knew so well to guide
- The wild sea-horses through the tide:
- The "Mountain-high" was the proud name
- By which the king was known to fame.
