What happened
The 12th-century Icelandic Book of Settlements, the Landnamabok, names Ingolfr Arnarson as Iceland's first permanent settler, arriving around 874 after a blood feud in Norway forced him to leave. By saga tradition he threw his high-seat pillars overboard as he approached the coast and vowed to settle wherever they washed ashore, then sent his slaves to find them; he built his farm at the site he named Reykjavik, 'smoky bay,' for its geothermal steam. Independent of the sagas, a distinct layer of volcanic ash preserved in Greenland ice and across Iceland has been dated to about 871 (plus or minus a few years), and this ash layer sits right at the base of the earliest layers of human occupation debris found in Icelandic soil.
Why it matters
The tephra layer gives archaeologists a fixed, independently dated marker for when permanent settlement began, largely matching the saga tradition's date without relying on it. Iceland's Age of Settlement, spanning roughly 870 to 930, filled an island with no prior permanent population and set the stage for the founding of the Althing.
How we know
The Landnamabok supplies the Ingolfr narrative, written centuries after the fact; the settlement-layer tephra dating is an independent scientific measurement from ice cores and soil sections, not derived from the sagas.
