Be a lupine beast, said Scandinavian folk hero (7)
I believe the answer is:
beowulf
'hero' is the definition.
(I have seen 'Germanic hero' mean 'beowulf' so perhaps 'hero' could also mean 'beowulf')
'be a lupine beast said scandinavian folk' is the wordplay.
I cannot really understand how this works, but
'be' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for beowulf that I've seen before include "An old tale" , "Old English saga" , "Old English epic poem" , "Anglo-Saxon epic poem" , "Germanic hero" .)
