A quote from Shakespeare’s tragedy Troilus and Cressida:
I tell thee I am mad
In Cressid's love: thou answer'st 'she is fair;'
Pour'st in the open ulcer of my heart
Her eyes, her hair, her cheek, her gait, her voice,
Handlest in thy discourse, O, that her hand,
In whose comparison all whites are ink,
Writing their own reproach, to whose soft seizure
The cygnet's down is harsh and spirit of sense
Hard as the palm of ploughman: this thou tell'st me,
As true thou tell'st me, when I say I love her;
Act I, Scene 1.
