“ Sir Thopas is going to fight the giant for the love and amusement of one who shone full bright; i. e. a fair lady, of course. But Sir Thopas, in dropping this mysterious hint to his merry men, refrains from saying much about it, as he had not yet seen the Fairy Queen, and had only the giant's word for her place of abode. The use of the past tense shone is artful; it implies that he wished them to think that he had seen his lady-love; or else that her beauty was to be taken for granted. Observe, too, that it is Sir Thopas, not Chaucer, who assigns to the giant his three heads. ”
