The Iliad 13.374–382

if in good sooth thou shalt accomplish all that thou didst promise to Dardanian Priam; and he promised thee his own daughter. Aye, and we too would promise the like and would bring all to pass, and would give thee the comeliest of the daughters of the son of Atreus, bringing her forth from Argos that thou mightest wed her; if only thou wilt make cause with us and sack the well-peopled city of Ilios. Nay, follow with us, that at the seafaring ships we may make agreement about the marriage, for thou mayest be sure we deal not hardly in exacting gifts of wooing.
