I've already made reference to the events of the Illuminating York festival, in which the story of Sweyn, his father and his son provided the inspiration for the light and sound display at Clifford's Tower. The background to the project and the artists' thoughts on the source material are to be found here: http://karenmonid.blogspot.co.uk/search/label/Triquetra
The generally disreputable Sweyn was cast in a more positive light in the JORVIK Viking Centre's summer exhibition, Heroes, which told the stories of some of the big personalities of the Viking period. Although Sweyn's credentials as a hero are questionable, we should consider his company within the exhibition: Harald Hardrada and Erik Bloodaxe, who also featured, are scarcely more heroic in any conventional sense of the word.
