Its a preposterous act of hubris, isn’t it? Pairing large scale video installations by American artist Bill Viola with drawings by Michelangelo can’t possibly illuminate our experience of either art form; or can it?

Exhibitions routinely claim to be a once in a lifetime experience, but there can be no doubt about the prince among them this year, the Royal Academy’s spectacular Charles I: King and Collector.

Familiarity breeds contempt, which makes it difficult to look at Edwin Landseer’s The Monarch of the Glen (pictured below). The reproduction of this proud beastie on T-towels, aprons, jigsaws and biscuit tins blinds one to the subtle nuances of the original painting.

One part of the brain, they tell us, responds to visual art and another, quite different, to music; we can't cope adequately with both at once. Which is why I'm often wary of those musical organisations which think that what we hear needs to be livened up with more to see: mixing Debussy with so-called "Impressionists", for instance, or Stravinsky with Cubism. A case can all the same be made for paintings which inspire composers, and vice versa, even if it's still a stretch to handle both simultaneously.

When, in 1853, Edward Burne-Jones (or Edward Jones as he then was) went up to Exeter College, Oxford, it could hardly have been expected that the course of his life would change so radically. His mother having died in childbirth, he was brought up by his father, a not particularly successful picture- and mirror-framer in the then mocked industrial city of Birmingham. Early on at King Edward’s School he was marked out as a pupil of promise and transferred to the classics department which enabled him to attend university and prepare for a career in the Church.

The most touching tribute to the relationship between two giants of early 20^th century art, Gustav Klimt and the much younger Egon Schiele, hangs in the first room of this fascinating exhibition at the Royal Academy  – Schiele’s poster for the 49th Secessionist exhibition in 1918. It shows a group of artists around a table, an empty chair at one end – that of Klimt, who had died of pneumonia in February.

Prints of all kinds; the first small wooden camera invented by Fox Talbot that made the negative positive process possible; Box Brownies and hundreds of other cameras from then until now. All that is just for starters in the V&A's new, fully-fledged, mini museum of photography.

It took 24 days to sell off the 4,000 items which Horace Walpole had amassed during 50 years of avid collecting. He bought a modest property beside the Thames in Twickenham in 1749 and, by 1790, had extended and transformed it into a fairy tale summer palace where he could throw lavish parties and show off his collection to friends and visitors.

What an ambitious project! Modern Couples: Art, Intimacy and the Avant-garde looks at over 40 couples or, in some cases, trios whose love galvanised them into creative activity either individually or in collaboration.

Pitched as “a tale of two artists”, the National Gallery’s big autumn show promises a history woven in shades of friendship and rivalry, marriage and family, privilege and hard graft. Andrea Mantegna and Giovanni Bellini were brothers-in-law, Mantegna’s marriage to Nicolosia Bellini in 1453 a strategic match that brought fresh blood to Venice’s greatest artistic dynasty.
