the new Roman Emperor and led a large Viking raid into the Mediterranean together with his protégée. They proceeded inland to the town of Luni, which they believed to be Rome at the time, but were unable to breach the town walls. To gain entry a tricky plan was devised: Hastein sent messengers to the bishop to say that, being deathly ill, he had a deathbed conversion and wished to receive Christian sacraments and/or to be buried on consecrated ground within their church. He was brought into the chapel with a small honor guard, then surprised the dismayed clerics by leaping from his stretcher. The Viking party then hacked its way to the town gates, which were promptly opened letting the rest of the army in. When they realised that Luni was not Rome, Björn and Hastein wished to investigate this city but changed their minds when they heard that the Romans were well prepared for defense. After returning to West Europe, the two men parted company. Björn was shipwrecked at the English coast and barely survived. He then went to Frisia where William says he died. There are some historical challenges with this account. Hastein appears in the contemporary sources later than Björn, and in order to be his foster-father would have been around his 80s when he died. That is certainly possible, citing the fact that their contemporaries, the Viking Rollo and King Harald Fairhair of Norway lived comparable lifespans. Luni is also known to have been plundered by Saracens. The Saga of Ragnar Lothbrok and Tale of Ragnar's Sons The story of Björn and his brothers, the sons of the Scandinavian king Ragnar Lodbrok, was retold in different versions throughout the Middle Ages. The Tale of Ragnar's Sons (Ragnarssona þáttr) is an Icelandic Fornaldar Saga from about the 14th century that combines traditional Norse oral history with legendary themes. It states that Björn was the son of Ragnar and Aslaug and that his brothers were Hvitserk, Ivar the Boneless, and Sigurd Snake-in-the-Eye. The tale also tells of Björn's half-brothers Eric and Agnar. The saga portrays Ragnar as the overlord of large parts of Sweden and possibly even Denmark. While he was still alive, Björn and his brothers left Sweden to conquer Zealand, Reidgotaland (here Jutland), Gotland, Öland and all the minor islands. They then settled at Lejre in Zealand, Denmark with Ivar the Boneless as their leader.
