How did Geoffrey Chaucer use Giovanni Boccaccio’s Teseida in The Canterbury Tales?

Geoffrey Chaucer utilized Giovanni Boccaccio’s Teseida as the primary source for "The Knight’s Tale," one of the stories included in The Canterbury Tales.12

Although the Teseida was not originally written for the Canterbury collection, Chaucer adapted the work to suit the character of the Knight, who serves as the narrator of the tale. The story follows the cousins Palamon and Arcite, who fall in love with Emelye, the sister of Hippolyta. Their rivalry culminates in a tournament held to decide who will win her hand. While Arcite emerges as the victor, he is subsequently thrown from his horse and dies, eventually leading to the marriage of Palamon and Emelye.1

By incorporating this chivalric romance into his larger work, Chaucer demonstrated his ability to explore diverse literary genres within the framework of his pilgrimage narrative.2
