The Iliad 9.94–95

He with good intent addressed their gathering and spake among them: Most glorious son of Atreus, Agamemnon, king of men, with thee will I begin and with thee make an end, for that thou art king over many hosts, and to thee Zeus hath vouchsafed the sceptre and judgements, that thou mayest take counsel for thy people.Therefore it beseemeth thee above all others both to speak and to hearken, and to fulfilll also for another whatsoever his heart may bid him speak for our profit; for on thee will depend whatsoever any man may begin. So will I speak what seemeth to me to be best. No man beside shall devise a better thoughtthan this I have in mind from old even until now, even since the day when thou, O king sprung from Zeus, didst take from the hut of the angry Achilles the damsel Briseïs and go thy way—in no wise according to our will. Nay, for I, mine own self, urgently sought to dissuade thee; but thou didst yield to thy lordly spirit,and upon a man most mighty, whom the very immortals honoured, didst thou put dishonour; for thou tookest away and keepest his prize. Howbeit let us still even now take thought how we may make amends, and persuade him with kindly gifts and with gentle words.
