In Norse mythology, Volsung was the son of Rerir and the eponymous ancestor of the ill-fortuned Volsung clan, which includes the well known Norse hero Sigurd. Volsung's story is recorded in the Volsung Cycle, a series of legends about the clan. The earliest extant versions of the cycle were recorded in medieval Iceland; the tales of the cycle were expanded with local Scandinavian folklore, and form the material of the epic poems in the Elder Edda and of Volsunga Saga, which preserves material from lost poems. Volsung is also the subject matter of the epic poem Nibelungenlied and is mentioned in the old English epic Beowulf.
