From Dante wiki--

New readers often wonder how such a serious work may be called a "comedy". In the classical sense the word comedy refers to works that reflect belief in an ordered universe, in which events tend toward not only a happy or amusing ending but one influenced by a Providential will that orders all things to an ultimate good. By this meaning of the word, as Dante himself allegedly wrote in a letter to Cangrande, the progression of the pilgrimage from Hell to Paradise is the paradigmatic expression of comedy, since the work begins with the pilgrim's moral confusion and ends with the vision of God.[99]

A number of other works are credited to Dante. Convivio ("The Banquet")[100] is a collection of his longest poems with an (unfinished) allegorical commentary. Monarchia ("Monarchy")[101] is a summary treatise of political philosophy in Latin which was condemned and burned after Dante's death[102][103] by the Papal Legate Bertrando del Poggetto; it argues for the necessity of a universal or global monarchy to establish universal peace in this life, and this monarchy's relationship to the Roman Catholic Church as guide to eternal peace.[104]
