Duke. And what 's her history?
Vio. A blank, my lord. She never told her love,
But let concealment, like a worm i' the bud,
Feed on her damask cheek: she pined in thought,
And with a green and yellow melancholy
She sat like patience on a monument,
Smiling at grief.
-- William Shakespeare (1564-1616), Twelfth Night
-- Act ii, Sc. 4
