Marking a Claim by Carrying Fire Around It

The Landnamabok, compiled from the twelfth century onward to record the ninth and tenth century settlement of Iceland, describes eldfoersla, fire carrying, as the recognized method for establishing a formal land claim: a settler walked or had fire carried around the perimeter of the territory being claimed, the flame's passage functioning as both a practical boundary marker visible to others and a ritual act consecrating the land to its new owner.

Later Icelandic law, drawing on this custom, set explicit limits on how much land a single fire carrying could legitimately claim, and further distinguished the maximum a man could claim from the smaller area recognized for a woman performing the same rite, a distinction the sagas preserve without extensive comment on its reasoning. The practice bound legal possession directly to ritual performance rather than treating the two as separate, so that a claim's validity rested as much on having correctly carried out the fire rite as on any subsequent occupation or improvement of the land itself. Landnamabok records dozens of individual settlers by name alongside the boundaries their fire marked out, making the text as much a land registry validated by ritual performance as a narrative history of the island's founding generation.
