Heimskringla; Or, The Chronicle of the Kings of Norway

42. OF EARL SVEIN.

Earl Svein and Einar Tambaskelfer gathered a large armed force, with which they came by the upper road into Gaulardal, and so down to Nidaros, with nearly 2000 men. King Olaf's men were out upon the Gaular ridge, and had a guard on horseback. They became aware that a force was coming down the Gaulardal, and they brought word of it to the king about midnight. The king got up immediately, ordered the people to be wakened, and they went on board of the ships, bearing all their clothes and arms on board, and all that they could take with them, and then rowed out of the river. Then came the earl's men to the town at the same moment, took all the Christmas provision, and set fire to the houses. King Olaf went out of the fjord down to Orkadal, and there landed the men from their ships. From Orkadal they went up to the mountains, and over the mountains eastwards into Gudbrandsdal. In the lines composed about Kleng Brusason, it is said that Earl Eirik burned the town of Nidaros:—

     "The king's half-finished hall,
     Rafters, root, and all,
     Is burned down by the river's side;
     The flame spreads o'er the city wide."
