Dante's Inferno was important at the time it was written because it reflected a growing trend toward the use of the vernacular (a writer's language, rather than Latin) in literature. This is sometimes viewed as a defining feature of the Renaissance. Dante also used Inferno as a social satire, by depicting some characters who were still living in real life as being tormented in Hell. Pope Boniface VIII, with whom Dante had feuded in life, is the most famous example of this. He is in Hell for fraud.
