Now, as regards the knot thou didst tie for me, then, methinks, I might have tied such a knot for thee that thou wouldst never have been king in Norway, when thou returnedst from thy campaign, and didst sail hither with but a single ship. Let, now, intelligent men judge, what advantage thou hast over me, and know ye, ye purse-proud braggarts, that there are yet men in Norway, who dare hold themselves your equals." This was the end of the "man-measuring"; and both kings were very wroth. Several other incidents are recorded, which show that Sigurd's jealousy of his brother would, at length, have brought about a breach of the peace, if death had not suddenly made an end of their intercourse. Eystein died at the age of thirty-three, August 29, 1122. The youngest brother, Olaf, had died (1115) before he reached manhood, and Sigurd was accordingly the sole ruler in the land. He was now free from the restraint, which Eystein's pacific disposition had imposed upon him, and he presently availed himself of his liberty to make a crusade into the Swedish province Smaaland, where paganism yet lingered (1123). He attacked the town of Kalmar, from which incident the war has been called the Kalmar War. Whether he succeeded in converting the pagans is not known; nor are any other results of the crusade recorded. After his return from this campaign, a great calamity befell him. Once, it is told, when he was in his bath, he called out, that there was a fish in the bath-tub, and ran about trying to catch it. It was the first symptom of the insanity which darkened the remaining years of his life. He was often sane for long periods; but, at times, he would sit and brood with wildly rolling eyes, or break out into paroxysms of wrath. Once, on the day of Pentecost, when his madness came upon him, he took a precious book,[A] which he had brought with him from Constantinople, and, gazing gloomily at Queen Malmfrid, who was sitting at his side, said: "How many things can change in a man's lifetime! When I returned to my country, I owned two things which seemed to me most precious,--this book and the queen. Now the one seems only more worthless than the other. The queen does not know how hideous she is; for a goat's horn is sticking out of her head. * * * And this book here is good for nothing."
