Celebrating the four ages of man, eight huge, semi-abstract paintings create a carnival atmosphere in the Serpentine’s central gallery. The freshness of Childhood is characterised by flowers, petals and stamens floating on a blue ground. The passions of Youth warrant a ground of hot orange crammed with circles and spirals jostling for space like amoeba in a petrie dish. Adulthood is dominated by a large, yellow gourd-like shape on a lavender ground; dancing in attendance are looping letters and clover-leaf swirls.

Was Leonardo da Vinci (1452-1519), who straddled the arts and science in such a unique way, several hundred years before his time? Did the painter-inventor-engineer really draw the prototypes for, inter alia, the aeroplane, the motor car, the helicopter and the submarine, or were they doodles to which history has ascribed more genius than they are due? This small but interesting exhibition attempts to answer those questions as it places his mechanical works under scientific scrutiny.

It is an inspired pairing: iconic images by the American photographer Richard Avedon (1923-2004) and the painter, printmaker and filmmaker Andy Warhol (1928-1987), almost all of whose mature work was based on the photographic image. They are together in a large exhibition at Gagosian, Britannia Street, itself one of the largest and most elegant commercial art spaces in London, designed by that cultural architectural duo Caruso St John.

In Hell, the souls of the damned endure cruelly imaginative punishments for all eternity. Corrupt churchmen are buried headfirst in the ground with their feet set on fire, and soothsayers, who in life presumed to be able to see into the future, have their heads turned 180 degrees and are forced to walk around looking backwards. Drawn in metalpoint strengthened here and there with ink, Botticelli’s lines are as fine as spider’s silk. Sometimes barely there at all, their extraordinary refinement lends a strange, jarring intensity to the violence and terror they depict.

The earliest known selfie is as old as the medium itself – literally. Hippolyte Bayard, one of the inventors of photography, pictured himself as a drowned man. His technique of photographic printing on paper had been upstaged by the daguerrotype, a metal plate alternative developed at the same time (1839) by Louis Daguerre. While Daguerre was showered with honours, Bayard was overlooked and, in disgust, he posed as a martyr to wasted endeavour; his hands stained with photographic chemicals, he slumps in a chair like a corpse newly dragged from the water. 

Art exhibitions hardly seem comparable with battery farming, and yet just as our insatiable appetite for cheap meat gives rise to some troubling consequences, so too does the demand for definitive exhibitions that require vulnerable works of art to be shipped around the world. And so it really is a cause for celebration that an exhibition exploring Eugène Delacroix’s influence in the 50 years following his death maintains its focus, argues its case and thoroughly immerses us in his work, without actually showing us any of his best known paintings.

Waldemar Januszczak always has a provoking agenda to shape his now nearly countless forays into television art history. In this four-part series he's out to challenge what he sees as the unthinking acceptance of the one-dimensional traditional and monopolistic version of the Renaissance.

When it got too hard to ship the original American edition across the Atlantic during the Great War, British Vogue appeared as a sister publication in the Condé Nast empire.

Dulwich Picture Gallery, the oldest public painting gallery anywhere with one of the world’s finest collections of Old Masters, has in recent years built up a deserved reputation for bringing to the British audience unfamiliar aspects of well known painters, along with reappraisals and new discoveries. Their latest show is the first-ever exhibition outside of Norway for that country's landscape painter Nikolai Astrup (1880-1928). 

The individual colleges of the University of Cambridge can call, when needed, on an astonishing international network of alumni for expert advice, consultation and financial support. Such is the backing for an exquisite new public gallery on the site of Edwardian stables in the grounds of Downing College there.
