The Divine Comedy by Dante Alighieri remains today one of the pillars upon which the European literary tradition has been built. Originally titled simply Commedia, Dante's masterpiece was written at the end of his life and finished just before his death in 1321. In an era of hand-copied manuscripts, it reached a large and appreciative audience quickly. By the year 1400, no fewer than 12 commentaries devoted to detailed expositions of its meaning had appeared to support the text. Giovanni Boccaccio wrote on the poet's life and in 1373-1374 delivered the first public lectures on Dante's Commedia.
