Why I tie about thy wrist,
Julia, this silken twist;
For what other reason is't
But to show thee how, in part,
Thou my pretty captive art?
But thy bond-slave is my heart:
'Tis but silk that bindeth thee,
Snap the thread and thou art free;
But 'tis otherwise with me;
I am bound and fast bound, so
That from thee I cannot go;
If I could, I would not so.

Robert Herrick [1591-1674]
