Nancy Spero & Marcus Coates, Serpentine Gallery

Angry art with a sense of social responsibility.

A maypole greets you on entry to the Serpentine Gallery; don’t expect a cheery celebration of spring, though. Nancy Spero’s installation Maypole: Take No Prisoners II (2008) is a scream of rage against violence and its hapless victims. Dangling from coloured ribbons, dozens of decapitated heads hang in the air like an explosion of shrapnel. Mouths gape open in pain and terror - or is it hatred? One can’t be sure, since some seem to be spitting venom from bloody tongues as though, even in their death throws, they are intent on spreading a gospel of vengeance and destruction.

Afghanistan: Crossroads of the Ancient World, British Museum

The history of this troubled nation comes alive through its treasures

I’m in an exhibition of ancient artefacts from Afghanistan, all from the National Museum at Kabul, but I may well have stumbled into the wrong room at the British Museum. I could be in the BM’s Hellenic section of Greek art, or, taking a few steps to my left, the Egyptian rooms. But then again… here are some sensual sculptures of curvaceous semi-clad women from India (main picture), while a little further on there’s a Chinese hand mirror and some boot buckles, the latter with Chinese dragons whose wings are of turquoise.

A New York transformation for Edinburgh's Metamorphoses

The Blitz wartime version of Ovid’s Metamorphoses that David Nice was raving about is New York-bound now, after winning one of the Edinburgh Fringe Festival’s most generous awards, the Carol Tambor Best of Edinburgh Award. This, set up in 2004 in perpetuity, gives the winning production an all-expenses paid trip to New York’s Off-Off-Broadway to stage the show for a run of up to a month (and to keep the net box office receipts).

Semele, Théâtre de Champs-Élysées

Genaux and De Niese among a superb cast and a pretty seductive McVicar staging

David McVicar's revival production of Handel's oratorio-cum-opera Semele isn't terribly clever or beautiful or impressive, or fecund with ideas or detail or emotion. But it does work. It does tell the story. And what brings colour to its initially rather pasty, unappealing face, and fire and heft to its anaemic belly, is sex and - best of all for those of you who will only be able to catch it in concert at the Barbican next week - one of the most impressive Handel casts I've heard for years.

Atlantis: The Evidence, BBC Two

Did Atlantis really exist? Set aside the crackpot theories and look at the evidence

Here’s a question: what have the eminent Victorian statesman and four-times prime minister William Gladstone and the Nazi Reichsführer Heinrich Himmler have in common? Well, if you didn’t catch last night’s Timewatch Special, you'd probably never guess. They were both obsessed with discovering that great, drowned civilisation of antique myth, Atlantis. Gladstone thought it was located somewhere on the South Atlantic, so he proposed a government sponsored expedition but was turned down by the treasury, and Himmler thought that the Ayrian master race was directly descended from Atlantians and that Tibet was the place, so he organised an expedition in 1939 (as if there wasn’t enough to occupy him that year). Excluding the finer details of master-race lineage, could either of them have been right? Did Atlantis, as first envisaged by Plato, and subsequently spawning thousands of books, really exist?

Tom Paulin on Translating Medea

The Irish poet's love affair with ancient Greek drama continues

I came to Medea because 26 years back, the Field Day Theatre Company in Derry - started by Brian Friel and Stephen Rea - asked me to a version of Antigone. Entitled The Riot Act, it was staged in the Guildhall in Derry in September 1984 and toured Ireland after that. It has been produced several times since then, most recently at the Gate Theatre in London.
