Maria Lassnig, the Austrian figurative painter best known for her emotionally complex self-portraits, died yesterday aged 94. She was virtually unknown in the UK until her solo exhibition at the Serpentine Gallery in 2008. In a compact survey which focused on recent work one self-portrait - You or Me, 2005 (main picture) - attracted the greatest attention. Here the artist, aged 86, wears a startled expression while pointing a gun at her temple and one straight at the viewer.

Yinka Shonibare MBE makes work from a less entrenched position than his many decorations suggest. This Member of the British Empire (he adopted the initials as part of his name after receiving the honour in 2005) is naturally also a Royal Academician, an Honorary Fellow of Goldsmiths, and has an honorary doctorate from the RCA. Shonibare is one of the most celebrated artists around, a fixture as well received as the ship in a bottle which occupied the Fourth Plinth in 2010 and which now has a permanent home outside the National Maritime Museum in Greenwich.

In a near-perfect, outward-looking Swiss city sharing borders with France and Germany, on a series of cloudless April days that felt more like balmy June than capricious April, anything seemed possible. The doors of perception which had slammed, I thought, irrevocably shut for me 45 minutes and four chords into the first act of Philip Glass’s Satyagraha could well open again in two concerts – London is to get three on a UK tour this week - around the musical Minimalist theme from Dennis Russell Davies and the excellent Basel Symphony Orchestra.

Alan Davie, who died on Saturday aged 93, was one of the great 20^th-century British artists, a life-long maverick whose explosive canvases cut a swathe through the provincial aridity of the postwar art scene.

Were it not for the bombs which rained down on Calais, its current Musée des Beaux-Arts would not exist. The 1966 building was part of a civic reconstruction programme, so it too is a war memorial of sorts. And it's now playing host to an exhibition dedicated to the idea of the monument which looks to commemorate the two world wars.

Addressing a crowd of journalists gathered at the press launch of her major retrospective at the Guggenheim Bilbao, Yoko Ono begins by telling us how cynical she is. It’s quite a claim considering it’s just about the last thing you’d ever think to call her. Perhaps she’s finally tired of being dismissed as a naive idealist. But no, it’s just a roundabout way for her to express her astonishment at the extraordinary architecture of Frank Gehry’s glinting, titanium-clad masterpiece, which opened 16 years ago in this Basque city of northern Spain.

It was very odd, in January this year, to see that Super-8 camera of Derek’s in a glass case and a few open notebooks in his beautiful italic handwriting in some other glass cases in the same room. There were five or six small-scale projections from his films in other rooms, including The Last of England, and some art works, but, somehow, Derek wasn’t there at all for me.

Whether fingerprint or labyrinth, the swirly logo for Marrakech Biennale 5 feels apt. The festival has left its mark upon the city. It questions Moroccan notions of identity. And, going by the tagline, “Where are we now?” it reflects the ease with which you can get lost in this rich and bewildering land.

The British Museum's exhibition The Vikings: Life and Legend promises to redefine the Viking age for a new generation. First seen at the National Mueum in Copenhagen, it has now travelled - much as the show's subjects once did - across the North Sea. It includes objects from 25 lending institutions spread across nine countries - 10 if you include Scotland, whose national law requires export licence. To celebrate the exhibition, theartsdesk invited Dr Gareth Williams to pick 10 exhibits that walk us through the Viking story.

The National Gallery recently embarked on a first: they acquired their first American painting. Men of the Docks, 1912, (main picture) may not be George Bellows’ most famous or best-regarded work; nonetheless, it’s a gritty and beautifully observed slice of New York life among the city’s dockside workers.
