You have a Trojan prisoner, call'd Antenor,
Yesterday took: Troy holds him very dear.
Oft have you--often have you thanks therefore--
Desired my Cressid in right great exchange,
Whom Troy hath still denied: but this Antenor,
I know, is such a wrest in their affairs
That their negotiations all must slack,
Wanting his manage; and they will almost
Give us a prince of blood, a son of Priam,
In change of him: let him be sent, great princes,
And he shall buy my daughter; and her presence
Shall quite strike off all service I have done,
In most accepted pain.
