Robert Macfarlane - an English fellow at Cambridge and a judge in 2004 - has said that he is keen for publishers to submit graphic novels, which he thinks would promote a "great discussion".
He pointed out that 19th century works including those by Charles Dickens and Wilkie Collins were published with illustrations, reports The Daily Telegraph.
This week saw the Costa novel and biography prize shortlists both including graphic novels for the first time - Days of Bagnold Summer by Joff Winterhart and Dotter of her Father's Eyes by Mary M Talbot and Bryan Talbot respectively.
Booker Prize-winner AS Byatt has said the novel is a very different artform. "They're not comparable," she told The Times.
"I think graphic novels can be a work of art just as much as a conventional novel, but I do think it's a completely different art to the kind of thing Hilary Mantel does."
