A new book which might interest lovers of ancient katabasis-narratives:
Judith Fletcher, Myths of the Underworld in Contemporary Culture: The
Backward Gaze. Classical presences. Oxford; New York: Oxford
University Press, 2019.
The book looks at the Greco-Roman sources (Orpheus, Heracles, et al.), and then at a number of disparate modern works, from Barth to The Sandman comics and lots in between.
