Treasures from the Hispanic Society Museum & Library are displayed as a monumental survey of Spanish art from Antiquity to the 20th century. The new exhibition stands as testament to the extraordinary vision of its founder, Archer M Huntington.

Have you noticed how exhibitions now seem to go on for ever and ever? Three months seems to be the norm, but five months is not unknown. Ever wondered why? In terms of time and money, mounting a major exhibition is incredibly expensive, of course.

First off, I must confess that fibre or textile art makes me queasy. I don’t know why, but all that threading, knotting, twisting, coiling and winding gives me the creeps. So it’s all the more extraordinary that I was blown away by Magdalena Abakanowicz’s huge woven sculptures.

Only a Eurostar day-trip away, at least from London, the Louvre is hosting an exceptional exhibition, which makes the journey to Paris well worthwhile. Things – A History of Still Life (Les choses – une histoire de la nature morte) is one of those massive shows that explores a complex theme in a thoroughly original and adventurous way.

Donna Fleming’s exhibition at the Pie Factory Gallery in Margate is called Apocalypse, which is confusing because it has nothing to do with the end of the world. Fleming does not even watch the news because she “does not want to think about miserable things”. Instead the title refers back to the Greek word that apocalypse is derived from, apokalypsis, which means uncovering.

The Royal Academy’s Making Modernism is a welcome introduction to seven women painters working in Germany at the beginning of the last century. It wouldn’t surprise me if you’d never heard of Gabriele Münter, Marianne Werefkin and Paula Modersohn-Becker even though they enjoyed international reputations during their lives, since their male counterparts (Kandinsky, Klee, Jawlensky and Macke) are not well known here either.

South African artist William Kentridge appears on video in his studio, twice. On the right he sits scribbling, waiting for an idea to surface. Meanwhile his alter ego stands impatiently by, trying to peek at his other half’s notes and, desperate for enlightenment, even reads a recipe out loud. The artist, it seems, doesn’t have a clue; he is as much in the dark as everyone else. A Lesson in Lethargy, 2010 offers a brief moment of humour in this relentlessly dark exhibition.

This rather disappointing documentary about the great American painter Edward Hopper (1882-1967) has such a dry parade of experts and such a slow linear narrative that it leaves plenty of time to be frustrated by all that’s been left out.

There stands Lucian Freud in Reflection with Two Children (Self-portrait), 1965 (main picture) towering over you, peering mercilessly down. Is that a look of scorn on his face or merely one of detachment? His two kids seem to be squirming and giggling beneath their father’s unblinking stare. Who wouldn’t be, especially when the huge lamps hanging overhead are reminiscent of an interrogation chamber? All the better to see you with, my dear.

Remember Gangnam Style, the music video that went viral in 2012? PSY’s cheeky lyrics and daft moves attracted 1.6 billion hits on YouTube, sparked dozens of parodies and turned the world on to K-pop. And that was just the beginning; K-pop has since mushroomed into a global phenomenon characterised by catchy tunes and fast-paced dance routines performed by beautiful young people in snappy outfits.
