Two recently decommissioned fighter jets are in the incongruous setting of Tate Britain's Duveen Galleries. One plane, polished to a mirror sheen, lies belly-up, like an injured animal; the other hangs suspended from the ceiling, its matt surface stripped of its combat colours and stripes, painted instead with faint feather markings, bringing to mind a giant, trussed-up bird. Its stilled presence is both powerfully majestic and inert.

It took Picasso four years to learn to paint like Raphael, but it took him a lifetime to paint like a child, or so he said. For Brancusi it wasn‘t a case of relearning childhood, but of being careful not to lose it in the first place. “When we are no longer children we are already dead,” he said.

There’s a rich vein of comic and satirical humour that runs through British art. Hogarth set the trend in the mid-1700s and heralded a golden age of graphic satirists. These included the three masters of the form: Gillray, Rowlandson and Cruickshank.

Thanks to the wonders of council applications, theartsdesk can bring you an exclusive preview of Marc Quinn's new sculptures to be placed outside the White Cube gallery on the grass of Hoxton Square.

Goldsmiths has produced 20 Turner Prize winners. It produced Damien Hirst and the majority of the Brit Art pack that caused such a Nineties sensation. It has attracted some pretty impressive tutors to its fine art department – ground-breaking artists in their own right, in fact. As such, the school is considered to be something of a star in itself. So what’s its secret? This BBC Four two-parter aimed to find out - and, you’ve guessed it, in keeping with a certain jaunty documentary-making tradition, it gave the participants just enough rope to hang themselves.

Is Eddie Izzard running a lot of marathons really worth three hour-long documentaries? No, but it was worth watching this first one. Having seen close personal friends gearing up to run the London Marathon, a process involving months of training sessions and muscle-group-specific workouts, it was barely believable to see a patently un-honed Izzard strolling into the Olympic Medical Institute in Eddie Izzard: Marathon Man, confessing that “I’ve run before, mainly for buses,” and proposing to run 1,100 miles round the UK in a month’s time.

It’s been a very good year for Beatlemania, with all the albums re-repackaged and the group going virtual in Rock Band. The BBC lobbed in their own Beatles season-ette, and one of the more striking images from their riot of documentary footage was of John Lennon escorting his Aunt Mimi up the steps onto the plane taking them to America, with her handbag and Sunday-best hat.

Damien Hirst this week unveiled No Love Lost, Blue Paintings among the Old Masters at the Wallace Collection. Although an exhibition of 25 new paintings by Britain's most talked-about artist might seem a change of direction, Hirst takes a different view. The new works, created between 2006 and 2008, mark the artist's return both to hands-on production and a quieter life at home. Is it the recession? Or is he getting old?
