Olaf's shrine, on condition that the king, on his return, should impose tithes for the support of the church. Before starting on his homeward way, Sigurd assisted Baldwin and Count Bertrand of Tripolis, at the sieges of Sidon and Akron, and received his share of the booty. He then betook himself to Constantinople, where games were celebrated in his honor by the Emperor Alexius, and a lavish magnificence was displayed in his entertainment, the like of which the Norsemen had never beheld. Sigurd forbade them, however, to show surprise at any thing they saw, lest the Greeks should conclude that they were barbarians, unaccustomed to luxury. In July, 1111, the king returned to Norway after an absence of three years and a half. He received henceforth the surname the Crusader (Jorsalfar). The thirst for glory which animated Sigurd was in striking contrast to the peaceful spirit which dwelt in his brother, Eystein. Upon the former had descended the restless ambition of Magnus Barefoot, while the latter had inherited his grandfather Olaf the Quiet's taste for building and calm delight in well-doing. While Sigurd scoured sea and land in search of fame, Eystein sat quietly at home, building churches, encouraging trade and industry, and improving the laws. By sheer dint of persuasion, gifts, and appeals to their self-interest, he gained the allegiance of the inhabitants of the Swedish province, Jemteland, which in the reign of Haakon the Good had belonged to Norway. Knowing the importance of the fisheries, as a source of national wealth, he had booths erected in Vaagen for the accommodation of the fishermen, and a church and parsonage for their spiritual welfare. At Agdeness, where many ships were wrecked, he made an artificial harbor by the construction of a mole. As a guide to sailors along the dangerous coast, he put up sea-marks and primitive light-houses, in the shape of fires which were lighted, after dark, on certain rocks and promontories. For the shelter of pilgrims to St. Olaf's shrine and other travellers, he built taverns on the Dovre Mountain, the passage of which had hitherto been perilous, on account of the snow and the absence of roads. Among the many churches which were erected by him were the Church of the Apostles, and St. Michael's in Bergen, St. Nicholas in Nidaros, and the rich Benedictine Monastery, Munkeliv.
