Note 5
III. GRENDEL THE MURDERER.

Of this difficult passage the following interpretations among others are given: (1) Though Grendel has frequented Heorot as a demon, he could not become ruler of the Danes, on account of his hostility to God. (2) Hrothgar was much grieved that Grendel had not appeared before his throne to receive presents. (3) He was not permitted to devastate the hall, on account of the Creator; i.e. God wished to make his visit fatal to him.—Ne … wisse (169) W. renders: Nor had he any desire to do so; ‘his’ being obj. gen. = danach.
