New York, late August 2010

I am at the opening of a swanky new gallery. Around me, the latest daubs by the hottest names adorn the walls of room after room. It’s worth mentioning a couple of discrepancies from your regular opening. This is a canapé-free environment, for one. There is no chilled white wine, no pretentious appraisal of carefully lit works. Nobody has come dressed to thrill. In fact, nobody has come at all. Apart from me.

We are still acknowledging our 21st-century debts to the energy, curiosity, determination and passion for discovery of a host of Victorian polymaths, and here is another. Sir Charles Eastlake (1793-1865) was a painter, scholar, author, collector and translator – fluent in German, French, Italian – and the first director of the National Gallery, rising above disputes with trustees and the government to set the scene for the role it plays today.

Does James Fox fancy himself as the Niall Ferguson of art history? I ask because clearly this latest addition to the growing pantheon of television art historians wants to do for British art what Ferguson sought to do for the British Empire. He wants us to stop apologising, and to admit that we’re simply the best, better than all the rest. And though I grant you he is similarly photogenic (with a touch of that swarthy, swaggering arrogance, too) the ratio of plausible statement to incredulity (my own, whilst spluttering and tweeting my incredulity) was considerably weighted towards the latter.

Gleaming, shimmering, full of pizzazz, glitz and unashamed bling, although of the 18th-century sort, as befits its role as the most cheerfully mixed up and glittering show of baubles in Bath, the Holburne Museum reopened in May after three years' closure. At a cost of £11.2 million the museum has been expanded, rebuilt, refurbished and renovated. Much more of the collection, newly installed after extensive conservation, is also on view than hitherto. The whole works a treat. As many visitors have turned up in the first month as normally come in a year.

Fake or Fortune? on BBC One, with Fiona Bruce and art dealer and sleuth Philip Mould, ought to have been called CSI: Cork Street for its blend of fine art and forensic science. They were trying to resolve whether a Monet was in fact a Monet, using a 240 million-pixel camera, Monet's own accountbook (which Fiona Bruce ran her ungloved fingers across) and plenty of ominous music. Next up: who killed Marat in David's picture?

It owns almost twice as many artworks as the Arts Council, and two-thirds of its 13,500-strong hoard is on display at any given time, yet it’s a collection the public never usually gets to see. Since its foundation in 1898, the Government Art Collection has been purchasing work by British artists not for the nation, but to hang exclusively in the corridors of power, from Downing Street to the British consulate’s office in Azerbaijan. Perhaps, in these cost-cutting times, it now feels impelled to justify its existence to the taxpayer by giving it a taster of its work – though, in all probability, the British taxpayer was probably unaware of its existence till now.

When people talk incessantly of freedom of speech, it means they are proud to have it or desperate to have it or desperate to defend it, or a mixture of all three. In Hong Kong, where I went at the end of May for the fourth edition of ART HK, people in the art world are constantly mentioning how free their speech is or else using a symbol to prove it - Ai Weiwei, the artist now imprisoned by China for "economic crimes" (ie subversive art). By speaking of Ai and displaying his work, one might almost get the impression China was not just to the north and three decades away from total control. Outside the art fair, alongside the Hong Kong flag, flies China's.

The story of the Pitmen Painters, a group of Northumbrian miners who decided to study art appreciation in their spare time and developed into a group of untrained but powerfully expressive artists, has been documented in a book by William Feaver and a play by Lee Hall. Robson Green's particular interest in the story stems from the fact that he's a miner's son, brought up in Dudley, a few miles south of the pitmen's hometown of Ashington.

Damien Hirst is finally getting his first UK retrospective in a public gallery next year, but the question seems to be, “Why now?” It seems both far too late and far too early, especially since Hirst has made no significant work in some years. That the Tate is organising it to coincide with the year of the Olympics, will, of course, be good for them: it will almost certainly see an unprecedented number of visitors, and tourists from around the world will flock to see it.
