2 adverbs to describe how to darkle

> Sentences: "A darkling plain Swept with confused alarms of and flight."

See his rich blood in purple torrents flows, And nature sallies in unbidden groans; Now mortal pangs distort his lovely form, His rosy beauties fade, his starry eyes Now darkling swim, and fix their closing beams; Now in short gasps his lab'ring spirit heaves, And weakly flutters on his falt'ring tongue, And struggles into sound.
