killed by the fall of his horse.[130] _Eystein_, the son of Adils, next swayed the sceptre of the Swedes. His reign was a troubled one, his kingdom being continually infested by the royal ships of Denmark and Norway, or, what was worse, by the fierce sea kings. “In those days,” says Snorro, “were many sea kings, who levied large forces, though they had no countries to rule. He was esteemed worthy to be a sea king who never slept under a tent, and never emptied his horn by the hearth side.” The most powerful enemy of Eystein was Solvi, a chief of the Jutes, whose piratical expeditions were known on many coasts. One night this marauder advanced to the tent where Eystein was entertaining his friends; and setting fire to the place, all within were consumed. To obtain the royal title, Solvi hastened to Sigtuna; and for a moment he enjoyed it: but the inhabitants rising to avenge their late king, and to free themselves from the new yoke, this adventurer soon bade farewell to empire and to life. The lawful successor of Eystein was his son _Yngvar_, who, being of a martial disposition, visited many coasts. But in 545 he was slain on that of Esthonia.[131] [Sidenote: 545 to 623.] The next person who filled the throne of the Ynglings, _Braut-Onund_, was a much wiser man than his predecessors. His great object was, to clear the forests, to drain the marshes of Swionia, and thus, to convert desert and useless into arable and pasture land. His efforts were crowned with success. Where the stagnant pool had stood, golden harvests waved; forests were replaced by huts full of industrious labourers; and highways were made to pass over mountain and fen. “Many,” says Snorro, “were the provincial kings subject to him.” But this patriotic monarch, like so many of the Ynglinga, came to an untimely end: as he and his retinue were one day in the mountains, they were overwhelmed by a huge avalanche. The sceptre now devolved to the unfortunate _Ingiald Illrada_, son of the deceased king. In his infancy this prince, we are told, was of too gentle, too mild a disposition, for the turbulent people with whom he had to deal. This defect, however, was cured by a peculiar diet,—that of roasted wolves’ hearts; and Ingiald became as ferocious as he had formerly been the reverse. But this change of character was not for the happiness of the Swedes; and he was destined to be the last of the Ynglings that should rule at Upsal. His first object was, to exterminate the local kings, who, like mushrooms, had sprung up in the country, and who, though subject to the descendants of Odin, frequently acted as if they were independent. In the entertainment which he gave at Upsal, alike to celebrate the obsequies of his father, and his own inauguration, his character was fully displayed. Here were six kings,—all who owed obedience to Ingiald, except the one of Sudermania,—with a great number of jarls, and other nobles. On these
