LONDON (AFP) - Street artist Banksy on Thursday (March 4) claimed responsibility for a painting on the wall of a former British prison that once held playwright Oscar Wilde.

The artwork shows a prisoner escaping on a rope made of bedsheets tied to a typewriter.

The elusive artist confirmed he was responsible in a video posted on his Instagram account.

The footage shows the artist carrying out the painting, and parodies the cult instructional videos of late American artist Bob Ross.

It opens with a clip of Ross saying: "Hello, I'm Bob Ross. I'd like to welcome you to The Joy Of Painting.

"Got all your materials out, ready to do a fantastic painting with me? Good."

The action then switches to Banksy as he executes his work, while a soundtrack of friendly advice from Ross plays over the top.

Reading Prison closed to prisoners in 2013 and is best known for housing Wilde, author of The Picture Of Dorian Gray (1890), during his two-year sentence of hard labour for "gross indecency".

Wilde's final work, the poem The Ballad Of Reading Gaol (1898), made the case for prison reform. He died at the age of 46 in 1900.

Britain's Ministry of Justice, the listed building's owner, is set to decide this month whether to turn it into an arts venue.
