As Damien Hirst’s Tate retrospective looms large on the horizon, the million-dollar question is whether the work has withstood the test of time. Will exciting and provocative sculptures like the pickled shark, which became an icon of Brit Art the minute it swam into view at the Saatchi Gallery in 1992, still send shivers down the spine, or has it become too familiar to arouse anything more than a yawn of recognition?

Two superb exhibitions at Tate Modern bring into public view the work of Japanese artist Yayoi Kusama and Italian conceptualist Alighiero Boetti; their work is not in any way connected except that, with their singular voices, each deserves much broader recognition.

Yayoi Kusama, one of Japan’s best-known living artists, has spent the past 34 years as a voluntary in-patient in a psychiatric hospital in Tokyo. Now 82, she was part of the New York avant-garde art scene of the Sixties, making work that anticipated both Andy Warhol’s repeated-motif “Cow Wallpaper” and Claes Oldenburg’s soft sculptures. Her nude happenings included orgies and naked gay weddings, over which she presided fully clothed like a psychedelic high priestess.

Highlights of the year are always interesting. Things you loved at the time do, sometimes surprisingly, fade very quickly. I really enjoyed the Gabriel Orozco retrospective at the Tate: I thought it inventive and exciting. But now I have hardly any memory of it, and can no longer visualise what enthused me. (Well, apart from the sweet photos of two scooters flirting with each other. But that’s really not enough.)

Last year, like every year, is a bit of a blur. I saw a lot, but all the good stuff seems to have clustered near the end. Maybe an end-of-year cultural bloat has finally settled. Anyway, to help jog the memory, I think I should start bottom-up. 

Brace yourselves for pure Damien Hirst madness next year. As well as Tate Modern’s retrospective survey opening in April, there will be a “worldwide” retrospective of Hirst’s spot paintings opening next month.

The Gagosian Gallery will be hosting the global exhibition of Hirst’s jaunty but dull spot paintings across all of its 11 galleries, from Hong Kong to Paris, and from New York to London, as well as in Los Angeles, Athens, Rome and Geneva.

Tate Modern’s lofty Turbine Hall is dominated by a giant CinemaScope screen flipped on its side so it becomes 42ft high and resembles a lift shaft or cathedral window. Instead of angels, saints or sinners, though, the starring role in Tacita Dean’s FILM is given to the building’s east window – the one hidden behind the huge screen. One of the main subjects of the film, then, is the very spot where you are standing – where much of the film was shot.

In recent years it seems we have seen an awful lot of Gerhard Richter. There have been three major exhibitions in London well within the last seven or eight years. One is hardly complaining, since there is always a demand to see “the world’s most influential living painter”, as he is often claimed to be (and not without some reason).

For her latest project, A Living Man Declared Dead and Other Chapters I-XVIII, American photographer Taryn Simon spent four years searching out families the world over whose lives have been defined by circumstances largely beyond their control – not natural calamities like floods, fires or earthquakes, but events orchestrated by other people. The stories are extraordinary.
