While this is the most famous, he did write other works, including:
* The Book of the Duchess
* Troilus and Criseyde
* House of Fame
* Legend of Good Women
* The Parliament of Fowls
* The Canterbury Tales (which includes numerous tales within)
However, it's important to remember that The Canterbury Tales is a massive, unfinished work, containing a multitude of tales, and is often considered his most significant achievement.
