“Divine Comedy” by an Italian poet of the Middle Ages Dante Alighieri appeared in uneasy early fourteenth century and is still regarded as the greatest piece of Italian poetical literature. Being a profound philosophical and mystical work, it is a true encyclopaedia of moral natural, theological knowledge, knowledge on botany, history, astronomy. “Divine Comedy” is built upon constant reiteration of three (divine triad) and ten (perfection). It consists of three parts - Hell, Purgatory and Paradise – each including 33 cantos plus additional canto for Hell, 100 in general. The Comedy has more that one stratum: it is both personal drama of the poet, and allegorical description of Florence life, and an account of the world. The first part tells of the inorganic, in “Purgatory” – of animate nature, and in “Paradise” the author presents his metaphysical views. “Hell” immerses readers into the depths of human vices; “Purgatory” gives hope that all sins can be disposed of when the long way of ascent begins. The journey of the poet through these three worlds appears a symbolic journey of the humanity in search of truth.
