Dante Alighieri (1265 - 1321) wrote the ‘Divina Commedia’, considered as a peak in world literature. 
It is a poem about a journey through three worlds of the hereafter: hell, mount purgatory and heaven. 
According to Jozef Rulof, Dante experienced actual spiritual out-of-body experiences and under leadership of his spiritual guide he visited dark and luminous spheres in the hereafter. 
Many of his descriptions and the illustrations by Gustave Doré (1832 - 1883) touch on the spiritual reality of the inhabitants of these spheres.
