A strange tale from Australia where an attempt to track down a secretive sculptor has resulted in legal threats from a Melbourne Gallery.

Journalists from the Australian Broadcasting Corporation (ABC) were warned off with legal letters after they began researching French artist Jean Paul Mangin whose plastic and polymer sculptures sell for up to $7,000 from the Studio Gallery Group run by Kerry Armstrong.

There is only one problem - Jean Paul Mangin does not seem to exist. ABC journalists could not contact him, he has no social media and they even went to Paris where they found no one of that name on the national art registry or registered to pay tax in France.

They did find a John Paul Chalwell Mangan - but he is dead and furthermore was Armstrong's father.

The gallery told reporters it rejected "the premise, tone and methods" of ABC's investigation and said "Jean Paul Mangin is the nom de plume of a real artist" and unmasking them would cause "serious psychological harm".

Their works remain on sale.

French artist JR is taking time off from wrapping the Pont Neuf in Paris in his monumental tribute to Christo and Jeanne-Claude to set up a slightly smaller installation for the Venice Biennale.

He will unveil his modern take on Paolo Veronese’s The Wedding at Cana on the facade of the city's Venice Venice Hotel on the Grand Canal from May 5 to 9.

The original 1563 painting, now in the collection of The Louvre, was created for the monastery of San Giorgio Maggiore in Venice.

Its modern counterpart includes photographs of 176 chefs, volunteers and guests from the Refettorio Paris charity which runs a community kitchen making thousands of cheap meals from food that would otherwise be wasted.

Visitors will be able to use the artwork's own dedicated digital platform to hear the voices of each person in the fresco and the story of their involvement in the project.

JR, whose Caverne du Pont Neuf runs in Paris from June 6 to 28, said he wanted the Venice installation to become "a necessary space of encounter where beauty ceases to be a privilege and becomes a shared human experience".

The journalist, formerly fashion editor at Vogue and editor of British Vogue, is curating The 90s: Art and Fashion this autumn.

Work by almost 70 artists and designers will go on show marking what the gallery described as the "period's surge of creative energy" including pieces by Jenny Saville, Sarah Lucas and Steve McQueen.

Fashion will feature courtesy of Vivienne Westwood and John Galliano among others while Mark Leckey's 1999 film Fiorucci Made Me Hardcore and Elaine Constantine’s photo series, Burn up Northampton, will look at the rise of different youth subcultures.

The show opens on October 8 and runs to February 14.

The curator of New York's High Line, Cecilia Alemani, said she was "so proud" to unveil its latest commission.

Tuan Andrew Nguyen’s The Light That Shines Through the Universe can be seen in the elevated park at 30th Street.

It is inspired by the monumental Bamiyan Buddhas which were destroyed by the Taliban in Afghanistan in 2001 - a moment captured forever by a film crew.

Nguyen's version includes hands made from brass from melted-down artillery shells, which Alemani said had "transformed the literal materials of war into gestures of fearlessness and compassion".
