In this rendition, Echo is not a nymph, or a princess, but a noble lady. She fell madly in love with Narcissus, so much so that she declared that she would die should he fail to love her in turn. Narcissus refuses, not because he despises all women, but merely because he is haughty and excessively proud of his own beauty.^[30]

Guillaume relays that on hearing Narcissus’ rejection, Echo's grief and anger were so great that she died at once. However, in a similar vein to the Lay of Narcissus, just before she dies, Echo calls out to Deus. She asks that Narcissus might one day be tormented by unrequited love as she had been, and, in so doing, understand how the spurned suffer.^[30]

As in the classical myth, Narcissus comes across a pool following a hunt. Though Echo prayed to Deus, and the tale notes that he answered her prayer, it is Amor who waits for Narcissus by the water. Amor causes Narcissus to fall for his own reflection, leading quickly to his death. The tale makes clear that this is not merely justice for Echo, but also punishment for Narcissus’ slight against love itself.^[30]

The tale concludes with an exhortation to all men warning them that, should they scorn their lovers, God will repay the offence.^[31]
