The Divine Comedy (La Divina Commedia) by Dante Alighieri is one of the greatest works of art known to the world, a "comedy", that became a "divine book" for ancestors. It is an encyclopedia of "moral, natural, philosophical and theological" knowledges, a tremendous synthesis of the feudal catholic ideology and the same tremendous epiphany that spread during the new culture times. A great poetic genius of the author put this comedy above the era and made it a legacy of centuries. It is divided into three parts: Inferno, Purgatory, Paradise.
