When we understand this we see clearly that the subject round which the alternative senses play must be twofold. And we must therefore consider the subject of this work [the Divine Comedy] as literally understood, and then its subject as allegorically intended. The subject of the whole work, then, taken in the literal sense only is "the state of souls after death" without qualification, for the whole progress of the work hinges on it and about it. Whereas if the work be taken allegorically, the subject is "man as by good or ill deserts, in the exercise of the freedom of his choice, he becomes liable to rewarding or punishing justice."
Florentine poet, writer, and philosopher (c. 1265–1321)
Dante Alighieri (c. 30 May 1265 – 13 September 1321), most likely baptized Durante di Alighiero degli Alighieri, was an Italian poet, writer and philosopher. His Divine Comedy, originally called Comedìa (modern Italian: Commedia) and later christened Divina by Giovanni Boccaccio, is widely considered one of the most important poems of the Middle Ages and the greatest literary work in the Italian language.

Hiis visis, manifestum est quod duplex oportet esse subiectum circa quod currant alterni sensus. Et ideo videndum est de subiecto huius operis, prout ad litteram accipitur; deinde de subiecto, prout allegorice sententiatur. Est ergo subiectum totius operis, litteraliter tantum accepti, status animarum post mortem simpliciter sumptus. Nam de illo et circa illum totius operis versatur processus. Si vero accipiatur opus allegorice, subiectum est homo, prout merendo et demerendo per arbitrii libertatem iustitie premiandi et puniendi obnoxius est.
For in every action what is primarily intended by the doer, whether he acts from natural necessity or out of free will, it is the disclosure of his own image. Hence it comes about that every doer, in so far as he does, takes delight in doing; since everything that is desires its own being, and since in action the being of the doer is somehow intensified, delight necessarily follows... Thus, nothing acts unless [by acting] it makes patent its latent self.
Nam in omni actione principaliter intenditur ab agente, sive necessitate naturae, sive voluntarie agat, propriam similitudinem explicare, unde fit, quod omne agens, in quantum huiusmodi, delectatur; quia, quum omne quod est appetat suum esse, ac in agendo agentis esse quodammodo amplietur, sequiturde necessitate delectatio... Nihil igitur agit, nisi tale existens, quale patiens fieri debet...
