How did Dante Chaucer express his departure from previous literary traditions?

Dante Chaucer developed previous literary traditions through innovative expression. Chaucer and Dante are the two most famous poets in the history of medieval literature. The reputation and status (importance of literary history) of the former is often not as good as that of the latter. Dante and his "Divine Comedy" sounded the death knell of the entire Middle Ages and set the stage for the West. The society brought the dawn of humanism, and its blessings lasted forever. Chaucer's influence was limited to England for a long time.
