Gentlest air thou breath of lovers
Vapour from a secret fire
Which by thee itself discovers
E're yet daring to aspire.
Softest note of whisper'd anguish
Harmony's refindest part
Striking whilst thou seem's to languish
Full upon the listeners' heart.
Safest messenger of passion
Stealing through a crowd of spies
Which constain the outward fashion
Close the lips and guard the eyes.
Shapeless sigh we ne're can show thee
Formed but to assault the ear
Yet e're to their cost they know thee
Ev'ry nymph may read thee here
(MS Folger, 'The Sigh', p. 254).
