 Adam of Bremen retells the story and adds that the island was "Heiligland", i.e., Heligoland.There is also a late-medieval legend of the origins of written Frisian laws.Wishing to assemble written lawcodes for all his subject peoples, Charlemagne summoned twelve representatives of the Frisian people, the "Āsegas" ('law-speakers'), and demanded they recite their people's laws.
