Dante wrote The Divine Comedy
(he wrote it roughly between 1310 - 1320), and it chronicles his journey through Hell, Purgatory, and Paradise.
John Milton was a contemporary of Shakespeare, and his greatest work is the epic poem Paradise Lost. In this poem Satan is a complex and tragic character. Two of his most famous lines could just as easily have been spoken by Ahab:
Tis better to rule in Hell than serve in Heaven
Which way I fly is Hell, myself am Hell
And in the lowest deep a lower deep
Still threatening to devour me opens wide
To which the Hell I suffer seems a Heaven
I studied both authors and poems when I was in college, took a year long course in Dante and a semester in Milton. Great, great works of literature, just timeless.
