The value of all the coins thrown into Rome's landmark Trevi Fountain in 2022.

Jeff Koons is back at Gagosian in New York for the first time in seven years with a new show of sculptures and paintings.

The works from his Porcelain Series include mirror-polished stainless steel sculptures based on porcelain figurines of mythical figures such as the Three Graces.

Koons said the work was "in dialogue with art from ancient times through history to this moment".

The show opens on November 13 at Gagosian's West 24th Street gallery.

It is only a month since London's National Gallery announced it had raised $498 million towards a major revamp of the building so it is good to see the money has not gone to its head.

The frugal institution, run by director Gabriele Finaldi for more than a decade, refuses to miss an opportunity to fill its coffers and is currently selling off a load of unwanted furniture.

Among the lots being offered next week by Bellmans auctioneers are sets of mahogany framed leather upholstered gallery benches, expected to make $1,595 each, and some plain mahogany benches estimated to sell for around $800.

A gallery spokesperson confirmed the benches being sold were all 1980's replicas which are not fire safe rather than solid slices of the gallery's Victorian heritage. They said the gallery retained designs and detailed photographs of the furniture should they wish to remake them in the future.

A graffiti-style art installation in Canterbury Cathedral has split public opinion before it even opens.

The display in the historic heart of the Church of England - home to its spiritual leader the Archbishop of Canterbury and first consecrated in 1070AD - includes a series of questions to God fixed on its stone pillars, walls and floors and is the work of poet Alex Vellis and curator Jacquiline Creswell.

The Cathedral itself admits it has provoked "very strong reactions" from the faithful, quoting one visitor who said it was "sacrilegious" while another said it made the ancient building "look like an underground car park".

Speaking in its defense, Dean of Canterbury David Montieth said the temporary graffiti gave it "an authenticity in what is said because it is unfiltered and not tidied up or sanitized".

The installation, called Hear Us, opens next Friday and runs to January 18.
