Descending into the nine circles of Hell is one of the key ideas set out in Dante's Inferno. Today's Free Thinking looks at the way his thinking and imagery have been taken up by other artists and writers. Rana Mitter's guests include the art historian Martin Kemp, the painter Emma Safe, the scholar and Dante website creator Deborah Parker and the New Generation Thinker Julia Hartley from Kings College London.

Professor Martin Kemp's latest book is called Visions of Heaven: Dante and the Art of Divine Light. He is a leading authority on the work of Leonardo da Vinci and has written explorations of science and art. Dr Julia Hartley has written a book called Reading Dante and Proust by Analogy. The clip from the Dante dramedy she's developing features Sam Ferguson as Dante and Matthew Salisbury as Guido Cavalcanti. Deborah Parker is Professor of Italian at the University of Virginia and has created worldofdante.org You can see examples of Emma Safe's artwork at https://www.emmasafe.com/
