LYRE, n. An ancient instrument of torture. The word is now used in a figurative sense to denote the poetic faculty, as in the following fiery lines of our great poet, Ella Wheeler Wilcox:
I sit astride Parnassus with my lyre,
And pick with care the disobedient wire.
That stupid shepherd lolling on his crook
With deaf attention scarcely deigns to look.
I bide my time, and it shall come at length,
When, with a Titan's energy and strength,
I'll grab a fistful of the strings, and O,
The word shall suffer when I let them go!—Farquharson Harris
2008 Update: The musical instrument plucked by muses in heaven until the Christian era advanced angels with harps, more expansive instruments better suited to lamenting the sinfulness of the churched.
