What is The Decameron primarily known for?

The Decameron is primarily recognized for its structure as a series of novellas told within a frame tale. Written by Giovanni Boccaccio during the 14th century, it consists of one hundred stories told by a group of ten young people who have fled plague-ridden Florence to a secluded villa. Each character recounts tales over ten days, leading to a rich tapestry of narratives that explore various themes, including love, morality, and human nature. This unique storytelling approach is a hallmark of The Decameron, distinguishing it as a significant work in the development of the short story genre and providing a window into the social and cultural context of the time.
