This exhibition – the UK's first major exploration of the history of Sicily – highlights two astonishing epochs in the cultural history of the island, with a small bridging section in between. Spanning 4,000 years and bringing together over 200 objects, it aims to "reveal the richness of the architectural, archaeological and artist legacies of Sicily", focusing on the latter half of the seventh century BC and the period of Norman enlightenment, from AD1000 to 1250.

With her strong, often fierce features and her convincing simulations of rage, Kate Fleetwood might have been born to play Medea. Unfortunately this isn’t Euripides’ Medea but Rachel Cusk’s free variations on the myth rather than the play.

Iliad is the third collaboration between National Theatre Wales and “the two Mikes”, directorial duo Pearson and Brookes. The pair have been responsible for two previous highlights of the still young company’s back catalogue, The Persians (2010) and Coriolan/us (2012). Aeschylus was re-imagined on a Brecon Beacons military range and Shakespeare recast in an RAF aircraft hangar, so it is perhaps surprising that the ultimate epic drama of war is staged in an actual theatre, the compact and modern Ffwrnes in Llanelli.

The Trojan War has been going on for nine years when Homer's account begins in The Iliad. Mike Pearson and Mike Brookes have been developing their version of the story, using Christopher Logue's War Music, for nearly half as long. True, when they staged The Persians by Aeschylus for National Theatre Wales in 2010, The Iliad was not yet on the agenda, but now they say that a through-line is clear from that production to their present National Theatre Wales project.

Heaven, or a lot of pagan gods at least, may know what was in the air 2500 years ago. Bettany Hughes has just finished her trilogy of philosophers from that millennium, and now we have Professor Andrew Wallace-Hadrill taking us genially around Athens, founded – you guessed – 2500 years ago and providing the template for cities ever since.

You don’t know Homer’s Iliad until you’ve heard it read aloud, all 24 books – not quite every line, but almost – and 16 hours of it. Yesterday's marathon was surely something like the events in which the Athenians kept the oral tradition going during their great Dionysiac festivals - in most things, at least, except the original feats of memory.

This is the real Greek, bloody-fantastical thing. After the fascinating but flawed attempt to bring Aeschylus’s Oresteia into the 21st century, the Almeida has turned to a more tradition-conscious kind of experiment with Euripides’ last and greatest masterpiece.

How do you live a good life? Is wealth a good thing? How do you create a just society? The United Kingdom's electorate recently pondered such questions in the polling booth, and made their decision. The Labour Party is agonising over them as it chooses its next leader. And yet while these anxieties may feel very now, they have deep roots. According to the historian and broadcaster Bettany Hughes, such questions first crystallised in the minds of three thinkers, born within a century of one another 2,500 years ago, who are the subject of her new series.

Modigliani’s short life was a template for countless aspiring artists who, in the period after his death in 1920, were only too willing to believe that a garret in Montmartre and a liking for absinthe held the secret to creative brilliance. While Modigliani certainly compounded poor health with a ruinous drink and drug addiction, this exhibition plays down his reputation as a hellraiser, suggesting instead an altogether quieter, although no less romantic character.

I’ve got no idea what the opposite of dumbing down might be. Swatting up? Whatever it is, it’s surely going to set the tone for the next couple of Friday nights on BBC Two, where Sex and the Church is as erudite a piece of television as we’re going to get in a long time.
