in
The Odyssey, by Homer (translated by: Butcher & Lang)

So spake he and all kept silence; and Alcinous alone answered him, saying: 'Stranger, forasmuch as these thy words are not ill-taken in our gathering, but thou wouldest fain show forth the valour which keeps thee company, being angry that yonder man stood by thee in the lists, and taunted thee, in such sort as no mortal would speak lightly of thine excellence, who had knowledge of sound words; nay now, mark my speech; so shalt thou have somewhat to tell another hero, when with thy wife and children thou suppest in thy halls, and recallest our prowess, what deeds Zeus bestoweth even upon us from our fathers' days even until now.†
Book 8

Book 14
