Final answer:
Beowulf is described using heightened senses in the epic, experiencing details of the natural world with extraordinary clarity and focus, which elevates him as a pivotal character in the narrative.
Step-by-step explanation:
Beowulf, in the epic poem, is portrayed with preternaturally keen physical senses, heightened by the 'awful disturbance' of his organic system. His acute perceptions allow him to record breathtaking details of the natural world with a stunning clarity. Beowulf's senses capture the ripples on the water feeling them upon his face, the distinct sounds they make, the intricate vision of forest foliage to the individual veining of leaves and even the tiny insects residing there.
He observes the prismatic colors in the dew on grass and experiences the auditory symphony of gnats humming, dragonflies beating their wings, and the music from water-spiders' leg strokes. His heightened sensory world is vivid, almost beyond human experience, as he hears the rush of a fish beneath the waters, and sees the world pivot around him- solidifying him as a central and pivotal figure within the poem's universe.
