But when Erato brushed her flowery lute,
What strains of sweetness whispered in the wind!
Soft as at evening when the shepherd's flute
To tones of melting love alone resigned,
Breathes through the windings of the silent vale;
Complaining accents tremble on the gale,
Or notes of ecstacy serenely roll.
So when the smiling muse of Cupid sung,
Her melody sighed out the sorrowing soul,
Or o'er her silken chords sweet notes of gladness rung.
