Drifting, floating, running, crowding: all these feelings of movement and stasis apply in a mesmerising selection of scenes, imagined and observed over 40 years by a true original. Michael Andrews (1928-1995), born and brought up in Norwich, studied at the Slade School during a golden period. His teachers included William Coldstream and Lucian Freud, and a highly individual cohort of fellow students who were to inhabit the heart of the art world, from Paula Rego to Craigie Aitchison.

The nine artists in this exhibition mainly paint large, eye-catching canvases; yet the most arresting image on show is a tiny, rather tentative picture of an unprepossessing man with yellow hair. It is hard to say why Richard Aldrich’s ethereal Future Portrait no 49, 2003 (main picture) is so compelling.

Born in Rome and taught by her artist father, Artemisia Gentileschi (1593-1652) led a colourfully energetic life. As an adolescent she was raped by her father’s assistant  – an episode which unusually, then as now, actually came to public trial – but she nevertheless became a confident, resolute woman, and a successful artist. She was vitally ambitious, portraying herself as La Pittura in her Self-Portrait as the Allegory of Painting, c.1638-9, an image at the heart of this exhibition.

When the French painter Fabienne Verdier told me she’d been invited to explore the relationship between painting and music at the world-famous Juilliard School in New York, I knew straight away that this unusual residency should be documented.

Those who frequent Cornwall know that most of its place names begin with one of three prefixes. Indeed, check your copy of Richard Carew’s Survey of Cornwall (1602) for the source of the rhyme: “By Tre, Pol and Pen / Shall ye know all Cornishmen”. (With thanks to Wiki). As to the suffixes, well there it’s open season. The name Poldark was Winston Graham’s invention – and, if we're being pedantic, the stress really should be on the second syllable.

Painted during his first trip to Paris in 1900, Picasso’s Le Moulin de la Galette is an outsider’s view of an exotic and intimidating new world. Men and women are seen as if through some strange distorting lens, their blurred, mask-like faces indistinct but for red-slit mouths and coal-black eyes. We seem to be in the room with them, and yet we are isolated. Even a woman looking out from the edge of the canvas gazes straight past us: if not invisible, we are certainly inconsequential.

Through the snowy wastes we crunched. The winter scenery was overwhelmingly beautiful and almost devoid of any human habitation: gorgeous mountains in the distance, the black waters of the fjords gleaming, the winter sun shining through the pale blue sky. And lo, here was Andrew Graham-Dixon, in woollen hat and furred windbreaker, to introduce us to centuries of Norwegian art.

Unswervingly confident, relaxed and assured, the élite of the 18^th century are currently arrayed on the walls of the Royal Academy, gazing down at us with the utmost assurance of their unassailable place in the world, bright eyed and dressed to match. The swirls of public reputation are unpredictable: here is a revelation, the art of one of the most successful and highly prized portraitists of his day, Jean-Etienne Liotard (1702-1789), now almost completely unknown except to specialists.

Free as air, but there was a very heavy price to pay for his ecstatic exploration of the sky by the Cornwall painter Peter Lanyon, who died in 1964, aged just 46, as a result of injuries received in a gliding accident. 

The Courtauld Gallery is known for its series of original, incisive, acute and intense exhibitions taking a sharply focused view of one aspect of an artist’s work. Often these provide a revelation and so it is here.

A finely honed and spacious selection dating from the 1950s to now, looks in acute focus at the work – a scatter of drawings, a print, but almost entirely paintings – of Frank Auerbach, (b 1931). An only child, he came without his family, from Berlin to England in 1939. His parents were murdered in the Holocaust. He is now one of the most remarkable painters of our time.
