The idea of heaven and hell is one of the oldest and most widespread religious beliefs of human civilization. In the history of western literature, this spiritual concept was frequently embedded in stories of underworld and heavenly journeys.

A variety of topics related to the nature of the universe, life on earth and the existence of the gods are explored in these stories. In the ancient western world, otherworldly journey narratives appeared in a wide variety of literary contexts including mythology, poetry and philosophical writings. Later in medieval times, otherworldly journey narratives remained a popular form of literary expression.

Rather than discussing mundane existence on earth, these tales describe a fantastic world filled with supernatural beings and miraculous happenings.
