His fans include Mick Jagger, Barry Humphries, Stephen King and former Archbishop of Canterbury Rowan Williams.
The Caerleon-born writer Arthur Machen still commands a cult following.
But the museum that houses the only collection of his work in the UK faces closure.
Watch the report from Mike Griffiths below:
Machen isn't exactly what you'd call a household name.
But more than 150 years after his birth, his fans are speaking up.
Watch our extended interview with Stewart Lee below:
Some of Machen's best-known works are the controversial The Great God Pan, the semi-autobiographical The Hill of Dreams, and The Bowmen.
The book tells a story of 15th century archers appearing on a First World War battlefield to protect British troops.
But it began to be taken at face value, giving rise to the myth of 'angels' actually appearing at the Battle of Mons.
Machen was born in Caerleon in 1863. A collection of his work and papers - the only one in the UK - is kept at the central library in nearby Newport.
But the building faces closure as Newport City Council tries to cut £10million from its budget.
It says the building, which also houses the city's museum, is in need of expensive repairs.
A consultation on the proposals is still going on, and ends on January 16.
Machen died in 1947. His fame may have risen and fallen over the years, but his fans are determined for his work to live on.
