Icelandic saga (4)
I believe the answer is:
edda
'icelandic saga' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for edda that I've seen before include "Yarn" , "series of stories" , "Old Scandinavian book of poetry, etc" , "Ancient Icelandic writings" , "couple of books in Norse" .)
