“Ingjald had a great feast prepared at Upsala, and intended to give an arvel after his father Önund, in a hall no less large or stately than the hall at Upsala. This he called the hall of the seven kings, for seven high-seats were in it. He sent men throughout Sweden, and invited kings and jarls and other high-born men; to this arvel came six kings, who were seated in the new-made hall. One of the high-seats which Ingjald had had prepared was empty. All the guests were seated in the new hall, and Ingjald had placed his hird and all his men in Upsala-hall. It was customary at that time that, where an arvel was made after the death of kings or jarls, the one who gave it and was to be led to the inheritance should sit on the step in front of the high-seat until the horn, called Bragi’s horn, was brought in, then he had to rise, take the horn, make a vow, and drain it to the bottom. After this he was to be led to the high-seat of his father, and then he was the owner of all his inheritance. Thus was it done here; when the horn of Bragi came in Ingjald rose, and took the large deer’s horn; he vowed that he would increase his realm by half in every quarter, or else die; then he drank it off. In the evening when the men were drunk, Ingjald said to Folkvid and Hulvid, the sons of Svipdag, that they and their men should arm themselves as was agreed upon. They went out to the new hall and set it on fire; six kings with all their men were burnt there, and those who tried to escape were soon slain. Thereupon Ingjald took possession of all the realms owned by these kings, and took taxes from them” (Ynglinga Saga, c. 40).[74] It appears that the right of sitting in the high-seat, conveyed with it the right to rule over household and land. “When King Harald (Fairhair) was eighty winters old he became heavy in his movements, so that he thought he could not journey about the country or conduct the affairs of the realm. He then led his son Eirik into his high-seat, and gave him power over the whole country. “When his other sons heard of this, Halfdan the black placed himself in a king’s high-seat and took the rule over the whole of Thrandheim, and all the Thrands supported him in this. But when the men of Vikin heard of it, they took Olaf as king over the whole of Vikin, which Eirik did not like” (Olaf Tryggvason, vol. i.; Fornmanna Sögur).
