Three paintings by Titian depicting stories from Ovid’s poem Metamorphoses welcome you to the National Gallery’s exhibition Metamorphosis: Titian 2012. Diana and Callisto shows Diana casting out the pregnant nymph Callisto from her company. Diana and Actaeon depicts the young Actaeon out hunting and stumbling into a sacred grotto where Diana and her nymphs are bathing; and in The Death of Actaeon, we see the goddess exacting vengeance on the intruder by turning him into a stag to be torn to pieces by his own hounds.

A birthday offering, a wedding celebration - with that, and one further creative collaboration ahead, Dame Monica Mason makes her farewell as director of the Royal Ballet after 10 years. The last programme of favourites from the store cupboard must always be a tricky one, but true to form the mistress of the great occasion (anniversaries have been a mainstay of her programming) picked rituals and ceremonies that stressed company ethos and values.

Male dancers are a puzzle to British audiences, where they are an uncomplicated, taken-for-granted treasure in Latin or Slav countries. I point this out gratuitously, as it's a point that wasn't touched upon by Melvyn Bragg's film about three iconic men of ballet, Rudolf Nureyev, Mikhail Baryshnikov and Carlos Acosta.

As Mrs Thatcher used to say, don’t bring me problems, bring me solutions. Solutions have been flung with a will at the problem ballet of Kenneth MacMillan’s last years, his orientalist fairytale The Prince of the Pagodas - the Royal Ballet’s retiring director Monica Mason revived it last night as one of her last presentations, determined that a new generation should have the chance to love it.

Ballo della Regina is a strange piece, for many reasons. A piece of minor Balanchine, it was created late in life for a dancer he clearly admired but who was not core to his vision. Strangest of all, he used music by Verdi, a composer whose music he had only choreographed to in his very early days as a journeyman opera-house ballet-master, when he did not get to choose.

Ballerina Tamara Rojo, director-designate of English National Ballet, is making waves even before she takes up her position in September. Next Monday she is a keynote speaker at a day of events at the Royal Society of Medicine launching the first-ever NHS treatment centre for injured dancers and rejecting the pressure for extreme thinness in performers.
