“It harrowed him
to hear the din of the loud banquet
every day in the hall, the harp being struck
and the clear song of a skilled poet
telling with mastery of a man’s beginnings,
how the Almighty had made the earth . . .”
Grendel’s main complaint doesn’t seem to be the noise per se. He makes real violence manifest from the symbolic violence done onto his own free noise space. Beats, structure, syllables, rhyme, meter lead to history, mastery, and ultimately the end of Grendel’s liberty, the lie to end all lies, a logical measure of the universe, λόγος.
