But if we suppose the story to be derived from the folk-tale, we have an explanation. For in the folk-tale, the companions and the hero await the foe singly, in succession: the turn of the hero comes last, after all his companions have been put to shame. But Beowulf, who is represented as having specially voyaged to Heorot in order to purge it, cannot leave the defence of the hall for the first night to one of his comrades. Hence the discomfiture of the comrade and the single-handed success of the hero have to be represented as simultaneous. The result is incongruous: Beowulf _has_ to look on whilst his comrade is killed.
