Sir Thomas More was very important because of gave his greatest work, Utopia. Modeled on Plato's Republic, written in Latin, finished and published in 1516, it describes an imaginary land, purged of the ostentation, greed, and violence of the English and European scenes that More surveyed. Interpretations of Utopia vary greatly. The dialogue form of book I and Utopia's continual irony suggest More's deliberate ambiguity about his intent. Whatever vision More really professed, Utopia persists and delights as the model for an important literary genre.
