Ciacco ([ˈtʃakko]) is one of the characters in the Divine Comedy by Dante Alighieri that was not yet well defined by historians. This is how he presents himself to Dante when he is in Hell: This way introducing himself allows us to interpret it in various ways, but one of the oldest commentators of the Comedy suggests a derogatory nature of this name: "Ciacco is said to be a pig's name, hence he was called this way for his gluttony."
