Dante’s writings, which are not only the Comedy but also Convivio, De vulgari eloquenti and De monarchia, are all absorbed with the literary technique that is called allegory. By adopting alleogyr as the technique of composition and interpretation, Dante has been able to communicate to the world in the way of unfolding his possible worlds beyond the threshold of his space and time. Allegory has been playing the role of indispensable art for Dante, as an intellectual writer, to share his own personal world with the readers, which was always the ongoing platform for his ambitious project to the salvation of human being; Dante thought that, only by casting his own autobigraphical experience and writings, he was able to share his world with the society and history. The term allegory comes from the Greek allosagoeruein, “to speak elsewhere than in the agora”: one thing is said, another signified. When we consider Dante’s allegory, we need to highlight it in exploring what he intends to imply and simultaneously what we want to signify with it. He emphasizes in Convivio that his writings are to be read literally first and then allegorically, which means that Dante’s writings is fully completed when they are understood in both superficial and deep strata. In other words, Dante’s allegory requires absolutely the cooperation by the readers; only by making the readers participating to his (literary process of) writings can his writings establish their own place where the author and the readers are able to exchange their experience and renew the possible worlds in association with their sociohistorical contexts. In sum, Dante’s allegory offers the chance to create our own new signfieds, rather than excavating the fixed, traditionally established one, so as to lead us to follow our own stars just as Brunetto Latini teaches to the pilgrim Dante in the inferno.
