Widewuto (also Viduutus, Vidvutus, Witowudi, Waidewut, Vaidevutis) was a legendary king of the pagan Prussians who ruled along with his elder brother, the high priest (Kriwe-Kriwajto) Bruteno in the 6th century AD. They are known from writings of 16th-century chroniclers Erasmus Stella , Simon Grunau, and Lucas David.[1] Though the legend lacks historical credibility, it became popular with medieval historians. It is unclear whether the legend was authentically Prussian (i.e. recorded from Prussian mythology) or was created by Grunau (possibly inspired by Biblical Moses and Aaron),[2] though Lithuanian researchers tend to support its authenticity.[3]
