Leon Kossoff, New Works, Annely Juda Fine Art

Kossoff: 'Christ Church, Spitalfields', 1999-2000

A rare exhibition teaches us to look, and then look again

It is one of the enduring mysteries of Leon Kossoff’s art. How does someone who uses such thick, impastoed paint and such muddy, earth-toned colours make his work so light, so delicate, so filled with grace? The more you look, the more mysterious is becomes.

Cézanne's Card Players, Courtauld Gallery

Cézanne's small but monumental series of paintings examined in depth

Give me a small side order of Cézannes over a great feast of Gauguins any day. This small, perfectly formed survey will surely be noted as one of the best exhibitions this year, the type of exhibition at which the Courtauld Gallery clearly excels: small, tightly focused, and exploring just one aspect of an artist’s output in order to illuminate his practice as a whole.

Thomas Lawrence: Regency Power and Brilliance, National Portrait Gallery

Sumptuous portraits of the movers and shakers of Regency England

Thomas Lawrence was a child prodigy; from the age of 11 he supported his family by making pastel drawings of the fashionable elite who spent the season in Bath. The next step for an aspiring young artist was to learn how to paint in oils and Lawrence taught himself by doing self-portraits. He learned fast. The first painting in this exhibition of sumptuous portraits shows a diffident 19-year-old sitting sideways and glancing nervously towards us, as though fearful that his efforts will be laughed at.

The Genius of British Art, Howard Jacobson, Channel 4

Howard Jacobson revels in the joy, and the anguish, of sex in Victorian art

Howard Jacobson, fresh from his Booker Prize triumph, was on an admirable mission last night: to rescue the good name of the Victorians. He wanted us to stop caricaturing our 19th-century forebears as prudish, self-righteous, pompous and hypocritical - you know, the sort of people who were so repressed that they went about covering piano legs in case thoughts should turn to the sensual curve of a lady’s well-turned ankle, but who were also notorious for sexual peccadillos involving underage maidservants, and worse.

Film: Over Your Cities Grass Will Grow

Anselm Kiefer's sculpture 'Over Your Cities Grass Will Grow': 'We see him swing huge giant concrete huts around by crane, flinging them on top of one another like they were toys'

Is modern art more fun to do than look at?

Action-movie season ain't over quite yet, folks. Sure. OK. Over Your Cities Grass Will Grow isn't exactly your conventional salute to Armageddon. No guns, no baddies, no hot babes, no long-haired hunks. The pace is slow. The dialogue's pretty non-existent - and mostly European. The setting is pastoral. The soundtrack is Ligeti. It is, in fact, mostly pure, unadulterated arthouse. But still Sophie Fiennes's documentary portrait of artist Anselm Kiefer, I would contend, could also be seen as one of the finest action movies ever made. Certainly, it's got to be the only one to feature a leading man who cycles around his Ardèche studio in roomy linen slacks and sandals.

Frieze Art Fair, Regent's Park

Damián Ortega's globe constructed from rocks of different sizes and colours at Kurimanzutto Gallery

Frieze frames itself with humour and innovation

Contemporary art can, unsurprisingly, become dated pretty quickly – the clue is in the name. Another of Damien Hirst’s mirrored cabinets of pills or of Gavin Turk’s piss-takes of Andy Warhol at the Frieze Art Fair in Regent’s Park is hardly the sort of sight which will enthuse hardened art-gallery goers.

Interview: Photographer Wolfgang Tillmans

Surprising collisions of light and time in the work of a unique photographer

The 2010 Brighton Photo Biennial has seen unprecedented numbers of visitors flock to the coast, and tonight will host a talk by one of the most original fine-art photographers working in Britain today. Wolfgang Tillmans will explore his unique and hugely influential approach to photography and the relationship between contemporary art and documentary and will undoubtedly cite his latest projects, the refreshing summer exhibition at the Serpentine Gallery and the recently launched, more audacious event at Liverpool’s Walker Art Gallery.

Turner Prize 2010, Tate Britain

Interesting, engaging and intelligent. You wouldn't believe it's the Turner Prize

There may be some who feel this year’s shortlist for the Turner Prize has done little to forge ahead with anything new, innovative and different. And then there may be others who will welcome the rather more established artists on this year’s list, that is those who have continued to steadily develop their practice for well over a decade, with no great surprises, such as Angela de La Cruz and Dexter Dalwood.

The Genius of British Art, David Starkey, Channel 4

Forgetting the rest of art history, David Starkey cunningly tries to convince us that the Tudors invented the portrait

David Starkey's polemical essay on royal portraiture is intriguing but fanciful

“Henry VIII is the only king whose shape we remember,” David Starkey tells us in the first of a new series of “polemical essays” on British art. To demonstrate, he reduces the king’s form to its bare Cubist geometry. He sketches a trapezoid for the chest – an impressive 54 inches in life, as attested by his made-to-measure suit of armour; two “chicken-wing” triangles for the puffed sleeves; two simple parallel lines for the wide-apart legs. Oh, and a small, inverted triangle for the codpiece. This last addition, as originally drawn-in for comedic value by the Tudor historian G R Elton, and fondly recalled, never failed to raise a titter amongst the callow students of Dr Starkey’s Cambridge undergraduate days.

Salvator Rosa: Bandits, Wilderness and Magic, Dulwich Picture Gallery

Salvator Rosa's self-portrait 'Philosophy' provides 'a glimpse of the self-promotional flair that would spark a personality cult'

Survey of the flamboyant artist who became a cult figure in his own lifetime

Mount Vesuvius blew its top in 1631, spewing molten lava into the sea and filling the air with ash clouds that reached as far as Constantinople. The eruption and accompanying earthquakes killed 3,000 people and caused widespread devastation, all of which made a lasting impression on the 16–year-old Salvator Rosa. As an artist he was to specialise in darkly tempestuous landscapes filled with menace in which small figures are dwarfed by towering cliffs, or beset by bandits, while storm clouds gather over ruined buildings and blasted trees.
