Comedy is the title which Dante gives to his trilogy and posterity has added the prefix adjective divine. The term comedy however is not used in the modern sense which suggests to us a light laughable drama written in a familiar style. "Comedy" Dante himself explains in his dedication of the poem, "is a certain kind of poetical narrative which differs from all others. It differs from tragedy in its subject matter in this way, that tragedy in the beginning is admirable and quiet, in its ending or catastrophe foul and horrible ... Comedy on the other hand, begins with adverse conditions, but its theme has a happy termination. Likewise they differ in their style of language, for tragedy is lofty and sublime, comedy lowly and humble. "From this it is evident why the present work is called a comedy, for if we consider the theme in its beginning it is horrible and foul because it is Hell; in its ending fortunate, desirable and joyful because it is Paradise: and if we consider the style of language the style is lowly and humble because it is the vulgar tongue in which even housewives hold converse." The theme of the poem Dante himself explains: "The subject of the work literally taken is the state of souls after death; this is the pivotal idea of the poem throughout its entire course. In the allegorical sense the poet treats of the hell of this world through which we are journeying as pilgrims, with the power of meriting and demeriting, and the subject is man, in as much as by his merits and demerits he is subject to divine Justice, remunerative or retributive" (Epis. dedicat. ad Can Grande). One of the earliest commentators amplifies the poet's statement. Benvenuto da Imola writes: "The matter or subject of this book is the state of the human soul both as connected with the human body and as separated from it. As the state of the whole is threefold, so does the author divide his work into three parts. A soul may be in sin; such a one even while it lives with the body, is morally speaking dead, and hence it is in moral Hell; when separated from the body, if it died incurably obstinate, it is in the actual Hell. Again a soul may be receding from vice: such a one while still in the body is in the moral Purgatory, or in the act of penance in which it purges away its sin; if separated, it is in the actual Purgatory. Yet even while living in the body, a soul is already in a manner in Paradise, for it exists in as great felicity as is possible in this life of misery: separated from the body, it is in the heavenly Paradise where there is true and perfect happiness, where it enjoys the vision of God." (Ozanam, Dante, p. 129.)
