Some years ago the Dulwich Picture Gallery invited Howard Hodgkin to exhibit alongside the Old Masters in their collection. I am not a fan of this vastly overrated artist, but even a diehard enthusiast must have found the juxtaposition cruel. How could Hodgkin’s crudely daubed, splishy-sploshy canvases (I exempt from the description a few works painted at the highpoint of his career in the mid-Seventies) bear scrutiny against works by Rubens or Rembrandt? They couldn’t, and the exhibition was a car crash. So how will an artist whose works appear similarly unrestrained and unstructured fare in his “conversation” with just one formidable Old Master?

A subtly haunting and brilliantly composed photograph by André Kertész lives on as a wistfully memorable image of exile: in Lost Cloud, 1937, a small, isolated cloud drifts we know not where next to a New York skyscraper. Kertész is one of the quintet of Hungarian Jewish photographers who are acknowledged as among the greatest of the last century. Kertész, Laszlo Moholy-Nagy, Robert Capa, Martin Munkácsi and Brassaï are the most familiar among the staggeringly accomplished Hungarian photographers who feature in the Royal Academy’s exhibition Eyewitness.

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?

An article in this week's New Yorker bemoans the death of drawing in art. Why has the emphasis on craft, Adam Gopnik writes, been replaced by concept? He has evidently not seen the fantastic noirish drawings of Marcel van Eeden at Sprueth Magers in Mayfair.

As one of the stars of the Moulin Rouge, she was variously known by the nicknames "La Mélinite", "Jane la Folle", and "L’Etrange". The first was after a brand of explosive, the other two attesting to a little craziness. Jane Avril’s eccentric dance movements evoked the involuntary spasms of female hysteria patients.

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.

Robin Rhode’s animations are pure pleasure; there’s perfection in their simplicity. They are so perfectly tuned, so light on their feet, that one simply wants to enjoy them; but because they are multilayered, they offer more than momentary pleasure. Rhode was born in South Africa and, in many ways, he is the Banksy of Johannesburg. In the late 1990s he began using the scruffy walls of the city as a canvas on which to make drawings which he describes as a “dreamscape to the impossible”.

Fred Sandback is one of the great overlooked of the Minimalist movement that developed in the 1960s. Both those words are important – “great” and “overlooked”: his work is genuinely great, and part of its greatness is the way it has overlooking built into it.

The world of artist and entomologist Tessa Farmer really is a world, wholly self-contained and free of human kind – unless you see her tiny warring fairies as symbolic of mankind’s conscience-free decimation of our planet’s environment and co-inhabitants. And it’s hard not to when you see them relentlessly picking over the corpse of a bird, mugging a mouse, or scrapping with a hornet, their tiny skeletal forms so industriously yet somehow amusingly destructive.
