by Unknown, The Laxdaela Saga — Chapter LXXIII: Bolli's Voyage (1906)
“ That winter the king sat east in Sarpsborg, and news spread from the east that the king was not likely to come north. Early in the spring the brothers got their ship ready and went east along the land. The journey sped well for them, and they got east to Sarpsborg, and went forthwith to meet King Olaf. The king gave a good welcome to Thorleik, his henchman, and his followers. Then the king asked who was that man of stately gait in the train of Thorleik; and Thorleik answered, "He is my brother, and is named Bolli." "He looks, indeed, a man of high mettle," said the king. ”
