Note note 1, p. 43 — THE SAGA OF ERIC THE RED
Reading edition
43-1 Thorlak was born in 1085, consecrated bishop in 1118, and died Feb. 1, 1133. These dates are definitely known, and are important. “The bishop’s birth-year being certainly known, one can reckon back, and according to the regular allowances, we shall have Hallfrid born about 1060, and her father about 1030, in Vinland, and Karlsefni as far back as 1000.” Vigfusson in Origines Islandicae, Vol. II., p. 592. Vigfusson seeks to corroborate the above by other allied lineages. If his deductions are correct, they are revolutionary with reference to the generally accepted chronology of the Vinland voyages. He is convinced that Leif belongs to an older generation than Karlsefni and his wife, and that Leif’s declining years coincide with Karlsefni’s appearance on the scene. The expeditions would then stand in the year 1025-1035, or 1030-1040, while Leif may have headed the first expedition, say in 1025. And he thinks that various things outside of the genealogies point to this. See Introduction, p. 12, of this volume.
