Gauguin has always been the poor relation in the art-legend sweepstakes. Unlike Van Gogh, there is no heartwarming story of overcoming lack of technical facility; no ghoulishly enjoyable story of genius crushed by madness. Instead, there is a story that veers from irritating to deeply unattractive: a businessman and Sunday painter, Gauguin acquired his technical skills across a range of art forms with almost insolent ease, before abandoning his wife and children in poverty to flee to ever-more exotic locales, where he lived with a succession of (in today’s terms) underage girls, some of whom he made pregnant while infected with syphilis, others of whom he rejected for being too "Western".

People always overlook how much of a hippie Richard Wagner was intellectually. His philosophical stance differs little from that of Neil from The Young Ones. It's a side of Wagner you can't get away from in Tristan und Isolde, with its endless railing against temporal realities and its search for universal oneness - yeah man, oneness.

Museum shows don’t often evoke a sense of smell, but without even trying, this Ballets Russes exhibition has visitors’ nostrils flared. The show is – intentionally – a feast for the eye, and even for the ear, with ballet scores (sometimes rudely overlapping) playing in every room. But smell?

Rachel Whiteread is best known for her exploration of space, of presence and absence, of how we look at what is present – and absent – in the textures of our lives. House, her life-sized cast of a house in a derelict street in East London, first brought her to fame, and more recently Untitled (Plinth), her mockingly affectionate take on the empty plinth in Trafalgar Square, a resin-cast replica of the plinth itself, literally shaped a new viewpoint of that absence in the heart of the West End.

Camille Silvy may be the least recognised of all the great photographic innovators of the 19th century. After a decade of almost ceaseless technical innovation, and astonishing output as the society portrait-photographer of the 1860s, he abruptly closed his London studio, aged only 34, returned to France, and, after a brief stint in the garde mobile in the Franco-Prussian War, spent much of the rest of his life in and out of asylums.

I must admit that I enjoy killing things and, since the target of my murderous instincts are clothes moths, fruit flies and, occasionally, rats or mice, society condones my bloodthirsty instincts. But while I get some satisfaction from my exploits, the women in Paula Rego’s drawings and prints appear to go about their murderous business with a mixture of resignation and detachment. These things have to be done, their world-weary faces seem to say, let’s expedite them with as little fuss as possible.

It’s not often you find yourself in an art gallery with the business end of a bullwhip whizzing inches from your nose. Wielded by a disconcertingly slight, black-haired woman who can barely be half its length, the terrifying instrument defines the dimly lit space with its whirling undulations and earsplitting crack, sending the gaggle of spectators cowering into adjacent rooms. Why there is also a grand piano present is probably only entirely known to the unnamed artist who brought this trickily titled exhibition into being.
