Tributes have been paid to art-world lawyer Michael Ward Stout who protected Robert Mapplethorpe's legacy for almost 40 years.

Stout helped the photographer set up his foundation a year before his death in 1989 having won him over with the gift of a silk bathrobe and by helping him talk one of Mapplethorpe's ex-boyfriends out of a suicide attempt.

His New York Times obituary recalled Stout saying that when "the situation calmed down, we realized that we had developed a friendship" and he ran Mapplethorpe's foundation for decades.

Stout, who also worked for Salvador Dali and with the estates of Jean-Michel Basquiat and gallerist Barbara Gladstone, was 83.

In a statement, the foundation said he was "instrumental in securing Mapplethorpe’s reputation as a fine artist and advancing the foundation’s mission to support HIV and AIDS research".

Olafur Eliasson will cover the floor of the ARoS Aarhus Art Museum with ice as part of a major partnership with the Danish institution.

It is part of his planned 2027 exhibition, Thin Ice, with a museum spokesperson saying it was intended to make visitors "attuned to their footsteps and the consequences of movement".

The museum, led by director Rebecca Matthews, has also acquired his 2025 work Presence which uses mirrors to flood one of its rooms with yellow sun-like light and will install his 2004 work, Waterfall, outside the building.

Danish-born Eliasson said the deal, which also includes the creation of a library dedicated to his work, aimed to show "museums can offer depth and focus for engaging with an artist’s practice in a more detailed, granular way."

The length of time a huge 5 tonne, 9.4-meter-wide, carved stone pediment has been in storage at the Rotterdam Museum. It is now on display on the site of the former hospital it was built for in 1716 until November 29 as part of the city's architecture biennale.

Two paintings have been newly attributed to Caravaggio in the space of 24 hours.

The first is a portrait of a young man claimed on Saturday by art historian Gianni Papi during a conference in Italy.

That was followed by an article in yesterday's edition of Italian newspaper La Repubblica featuring another academic, Maria Cristina Terzaghi, who says she found the original version of the artist's Young Man with a Vase of Roses in a private collection in France.

Papi has yet to publish the evidence behind his claim - it will be made public when the wider conference proceedings are published - but Terzaghi says she has no doubt the work she saw in Paris is "the Caravaggio painting that has inspired dreams for nearly a century".

Around 20,000 people poured into Sydney's $915 million Powerhouse Parramatta on its opening weekend but one notable person was conspicuous by her absence.

Former chief executive Lisa Havilah, who was stood down earlier this year pending an investigation into finance and governance issues, was not completely forgotten.

Around 800 people have signed a petition demanding her return and New South Wales Premier Chris Minns, who formally opened the building on Saturday, paid tribute "to the enormous work" carried out by Havilah while repeating the need "for an independent investigation".

The Sydney Morning Herald reported a return to Sydney was "unlikely" but said the museum's success could "eventually ease a move into philanthropic foundations or the international gallery sector" and hinted she may find a new job in London.

1 - Pepon Osorio and Ming Smith have been awarded fellowships by the New York-based Center for Art, Research and Alliances (CARA). Its executive director Manuela Moscoso said the awards, which are worth $75,000 and also include tailored support for each artist, recognized that "sustaining an artistic practice also means supporting the life around it".

2 - Eva Chow has announced she is standing down as co-chair of the Los Angeles County Museum of Art (LACMA) Art + Film Gala after 15 years. This year's event was on Saturday and raised around $7 million with attendees including Chow's co-chair Leonardo DiCaprio, Ed Ruscha, Timothee Chalamet and Vija Celmins who was honored on the night.

3 - Thomas Ruff will be in conversation on Thursday at the Grand Palais as part of this year's Paris Photo. The event with Florian Ebner, head of photography at the Centre Pompidou, comes after the German artist was invited to install a 36-meter-long retrospective installation in the building which goes on show from Thursday.

4 - Two large still-life fruit and flower paintings are expected to fetch $10.7 million at auction at Christie's in London on December 8. The panels by Jan van Huysum have remained together as a pair since being painted in the 1730s and have spent the last 80 years in a private English collection.
