'Twas thine own genius gave the final blow,
And help'd to plant the wound that laid thee low:
So the struck eagle, stretch'd upon the plain,
No more through rolling clouds to soar again,
View'd his own feather on the fatal dart,
And wing'd the shaft that quiver'd in his heart.

Line 826. A number of authors have addressed this common motif of an eagle shot with an eagle-feather arrow - English Bards and Scotch Reviewers (1809)
