Note 332 — Chapter LX · SWEIN SLAYS SWEIN.
Gilbert Goudie translation
Probably a large flagstone set on end to serve as a partition-wall. This is a common feature of the ancient structures in Caithness and Orkney. It was in the shadow of this flagstone that Swein, Asleif’s son, stood when he killed Swein Brióstreip (see p. 95).
