The Georgian Chronicles
Aside from the Ingvar runestones, there are no surviving Swedish sources that mention Ingvar, but there is the "Yngvars saga víðförla" and three Icelandic annals which mention his death under the year 1041: "Annales regii", the "Lögmanns annáll" and the "Flateyarbók annals". These three annals are probably based on Sturla Þórðarson's compilation. Swedish archeologist and historian Mats G. Larsson notes that "The Georgian Chronicles" mentions a visit from a viking expedition in the year 1040, which correlates with the description of such a meeting in "Yngvars saga víðförla".
