The artwork, which has been vandalised for a second time, was covered with slogans, including some that were anti-Semitic.
Kapoor, who is Jewish of Sephardic Iraqi origin, said although he found the graffiti “offensive” and “slightly frightening”, he was “in the middle of making the decision” that he wanted the slogans to stay.
“I think I have made the decision to leave, or I am in the middle of making the decision once I can extricate myself sufficiently from it, to leave the graffiti as part of the work. It is vile, so to turn what I hoped always was an act of affirmation as a work of art into something else, into a kind of lament to a state of intolerance,” he told Radio 4’s Today programme.
He said the vandalism gave greater complex meaning to the sculpture’s title, but said the decision to leave the offensive graffiti was still one he was “struggling with”.
“I very controversially call this work ‘Dirty Corner’…meaning or implying all sorts of thing, some rather sexual, but also human ideas about a certain loss of dignity.
“Now what this does is emphasise the dirtiness in so many ways. Dirty politics, disregard for common humanity, religious and otherwise. All these things are emphasised here, so i would say that as violent as it is, and deep offensive, but to leave it there is quite an assault on the viewer.”
He added it may be hard to eradicate the vandalism and restore the artwork from a “physical point of view”.
Banned, censored and 'offensive' artworks
Banned, censored and 'offensive' artworks
1/8 'My Bed' - Tracey Emin
Emin, one of the Young British Artists, created arguably her most iconic and controversial piece of art with 'My Bed'. It was short-listed for the 1999 Tuner Prize but sparked public outrage and a media furore. Emin's own bed is displayed here, surrounded by evidence of her sexual, self-destructive exploits. Stained sheets, fag butts, empty beer bottles, condom and worn underwear can all be seen in this image of suicidal depression following a major break-up.
2/8 'Christ You Know It Ain't Easy' - Sarah Lucas
This 3D piece by English artist and Tracey Emin contemporary Sarah Lucas is made from cigarette butts and depicts Christ being crucified on the cross of the English flag. It is thought to be a comment on the difficulty of quitting smoking. Lucas took up the habit aged 9. Much of her work is designed to be shocking and provocative - someone is always offended.
3/8 'Fountain' - Marcel Duchamp
This scandalous porcelain urinal, signed R.Mutt, was rejected by the Society of Independent Artists in 1917 even though the rules stated that any submission would be accepted from artists who paid the fee. Pictured here is a replica of the 1917 piece. The original is believed lost. 'Fountain' is an example of Duchamp's revolutionary 'readymades' - ordinary manufactured objects designated by the artist as art.
4/8 'The Holy Virgin Mary' - Chris Ofili
The provocative Sensation exhibit at the Brooklyn Art Museum in 1999 caused great offence. Nigerian artist Ofili's depiction of an African Madonna surrounded by black bottoms and elephant poo was called 'anti-Catholic' and 'horrible' by New York's mayor at the time. So 'horrible' that Rudy Giuliani filed a lawsuit against the museum.
5/8 'Immersion Piss Christ' - Andres Serrano
Two Catholic activists partially destroyed US artist Serrano's artwork while it was on display in the south of France. Created in 1987, it represents a small plastic crucifix submerged in a glass of the artist's own urine.
6/8 'Western-Christian Civilization' - Leon Ferrari
Argentine conceptual artist Ferrari often dealt with power and religion in his work, using images of Jesus and the Virgin Mary with cages, frying pans and even meat blenders. Showing Christ crucified on a fighter plane, 'Western-Christian Civilization' was a protest work against the Vietnam War. Governments were constantly battling against Ferrari - he was exiled from Brazil and a 2004 exhibition of his work was temporarily forced to close when Pope Francis intervened.
7/8 'Bacchante and Infant Faun' - Frederick William MacMonnies
This bronze statue caused an uproar in 1854 when an architect tried to erect it in the courtyard of the Boston Public Library. Modern viewers will see little to get het up about but the nude Roman wine deity's 'drunken indecency' offended the Women's Christian Temperance Union. It was taken down to the more liberal New York instead and is now exhibited in the Metropolitan Museum of Art. MacMonnies earned worldwide fame as a result.
8/8 'Saint Bartholomew, Exquisite Pain' - Damien Hirst
No stranger to controversy, Hirst's original sculpture had no fig leaf to protect his modesty. The artist added the extra detail to prevent issues with Chinese collectors and left it in when the sculpture was displayed in Qatar. Nudity can offend Islamic culture, particularly in places where the general public has not been exposed to contemporary art.
The artist denied the sculpture was a representation of “the vagina of the queen who took power”, which he was originally quoted as saying when it was first installed at the Palace of Versailles.
“It’s an abstract work, it bears little [resemblance to the vagina]. What I did say is ‘she’ reigns loud and clear in the context of this place of, let’s say, the French state.”Reuse content
