Under these circumstances it was but natural that the chieftains began to repent of their rebellion against King Olaf. Einar Thambarskelver, who prided himself on his absence from the battle of Stiklestad, was especially active in awakening regret among the Trönders at his death, and indignation at the rule of the Danes. He sent for Bishop Grimkel, who was living as an exile in Sweden, and agreed with him upon a plan of action. The bishop sent for the peasant Thorgils, who revealed the spot where he had buried the king. Permission was obtained from King Sweyn to bring the corpse to Nidaros, where it was placed in a splendid sarcophagus and interred under the altar in the Church of St. Clement (Aug. 1031). Although nearly a year had elapsed since the first burial, it was asserted that there was no trace of decay on the body and that the hair and the nails had grown. Einar and the bishop, at all events, encouraged such reports, and they grew in number and minuteness of convincing details. Grimkel now declared Olaf to be a saint, and Sweyn and Alfifa, though they raised many objections, dared no longer profess their disbelief. The 29th of July was set apart for the commemoration of his martyrdom. For the first time in their history the Norsemen felt themselves as one nation, united in their indignation against their foreign rulers and in their regret and veneration for the martyred king. If Sweyn and Alfifa were aware of the sentiment with which they were regarded, they chose to ignore it. They were, however, not prepared for open defiance, and the events of 1033 must have taken them by surprise. In that year, a young man calling himself Tryggve, and professing to be a son of Olaf Tryggvesson and his wife Gyda, came from England or Ireland with a band of warriors and claimed the throne of Norway as his inheritance. Sweyn called upon the chiefs to aid him in punishing the pretender, but Einar Thambarskelver, Kalf Arnesson, and many other magnates, refused to follow him. With those who still recognized his authority the king sailed southward and defeated Tryggve in a short battle in Sognesund. On his return he and Alfifa met the Trönders at the _thing_ and listened to their complaints, but could give them no satisfaction. Then Einar Thambarskelver said aloud and in the hearing of many: "I was not a friend of King Olaf; but the Trönders proved themselves to be poor merchants when they sold their king and got in his place a mare with her colt. The king cannot speak, and his mother only wishes what is bad and has the power to do it."
