Here are a couple of websites with great maps and illustrations of the Divine Comedy.
The World of Dante: it provides galleries with illustrations from Thompson, Botticelli, Vellutello, Dore’, and others; great maps of Inferno, Purgatorio, and Paradiso; a timeline, and other resources.
The Divine Comedy Gallery: it has images from various illustrated editions of the Comedy including a very powerful one by Salvador Dali’, maps, and pages from medieval manuscripts.
Here is one last map of Inferno
On the occasion of the 750th anniversary of Dante’s birth (May 4, 2015), Pope Francis said that the great Florentine poet “still has much to say and to offer through his immortal works to those who wish to follow the route of true knowledge and authentic discovery of the self, the world and the profound and transcendent meaning of existence.” He encouraged the faithful to read the Divine Comedy and use it as a spiritual guide during the Holy Year of Mercy. According to the Holy Father, in fact, Dante’s masterpiece offers an opportunity to “rediscover the lost or obscured meaning of our human path and to hope to see again the glowing horizon on which the dignity of the human person shines in its fullness.”
A free resource to help you seeing the Comedy as a guide to the spiritual life is offered by Dr. Jason Baxter, Assistant Professor of Humanities at Wyoming Catholic College through a series of videos on each Cantica titled Dante in the Year of Mercy . The first one is already available online, while the others will be posted in the upcoming weeks.
