The question how far the use of fiction was permitted in heroic poetry is of course one to which we cannot possibly hope to give a definite answer. All poetry which deserves the name claims to do something more than provide a bare record of facts. According to the ancient definition its proper function is to express the universal rather than the particular–what may happen or may have happened rather than what has happened. Some freedom of play for the imagination is therefore essential. These remarks hold good for early Teutonic poetry just as much as for Greek. If we could recover the poems recited in Attila's presence (cf. p. 84) we should doubtless find that they contained far more than a mere statement of facts. In the works which have come down to us however the degree to which freedom is allowed to the imagination varies very greatly from case to case. Thus in the poem on the battle of Brunanburh it is restricted within comparatively narrow limits, while in the almost contemporaneous Hákonarmál the historical fact on which the poem is based is very largely obscured by a wholly fictitious narrative. We may naturally expect that the authors of heroic poems likewise differed in the treatment of their subjects, though not necessarily to the same degree.

As an instance of a poem which obviously contains a large amount of fiction we can hardly do better than take the Anglo-Saxon Widsith.
