Each prominent man or chief lived on his estate with his family, followers, and servants. The collection of buildings they occupied was called _bœr_;[184] they were of different styles, and varied in number according to the power, wealth, and taste of the owners, and often seem to have been far apart from each other; every house was known by a different name. These buildings appear to have been built so as to form a quadrangle, the front facing an open space or grass plot called _tún_, the whole being surrounded by a fence called gard,[185] through which the entrance was by a gate, “_grind_,” or gateway, “_hlid_.” “Raudulf lived in the days of King St. Olaf in the Austrdal (Österdal valley), when the king was journeying round the land and forcing people to embrace Christianity. He sent his sons to King Olaf, and invited him home to a feast. It was rather late in the day when the king came to Raud, with two hundred men; he saw high and well-closed fences, and when they came to the gate it was open, but nevertheless well guarded.... When the king rode in, Raud bondi stood there with his sons and many people. Raud received him and his men well; they alighted from their horses. The king asked the bondi: ‘Is this fine house which I see here in the enclosure a church?’ The bondi answered: ‘It is my sleeping-house, which was built this summer, and is now just finished;’ the whole roof of the house was shingle-covered, and tarred. Then they went to the sitting-room, and the king saw that it was very large; it was roofed with planks and tarred” (Fornmanna Sögur, v. 331). The finest buildings were called _holl_ (hall), and were only built by kings, chiefs, or jarls.[186] Another building, called _sal_,[187] seems to have been the same as the hall, as it was built for the reception of guests. Here and there we have descriptions of halls belonging to prominent chiefs, richly ornamented with carvings, which sometimes represented the deeds of warriors; and were it not for some of these mementoes, which have been rescued from oblivion and decay, we might doubt that the art of carving had been carried to such perfection as it was. Walls, doors, beds, seats, &c., are mentioned as being richly carved. “Olaf Höskuldsson had a hall made in Hjardarholt larger and more magnificent than people had before seen; on the wall and on the ceiling famous Sagas were carved with such skill that the hall was thought to be far more splendid when the hangings were taken down” (Laxdæla, c. 29). “It was customary at that time to have large halls at the bœr, at which the people sat before long fires in the evening; tables were placed in front of the men, who afterward slept alongside the walls, away from the fires. During the daytime the women carded and spun wool in these halls” (Gretti’s Saga, ch. xv.). Some of the churches and farm-houses built in the beginning of the Christian era, and some of the doors, testify to the durability of their wooden structures.
