Great ballet dancers who boldly turn away from a stellar international career to grow a national ballet company in their homelands are few, but legendary. Alicia Alonso did it in Cuba, Ninette de Valois did it in Britain. And, dancing across the cusp of even more perilous political weather than either, so did the brilliant Bolshoi Ballet star Nina Ananiashvili when 20 years ago she left the world stage to return to her broken and battered native Georgia and generate its own classical ballet company. 

In uncertain times like these, the single thing that every flagship ballet company needs is a convincing iteration of a 19th-century blockbuster. New works are all very well and necessary, but they don’t have the pulling power of Swan Lake, or the staying power. The Royal Ballet’s previous production served the company well for three decades, more than justifying the original investment.

Nobody ever forgets The Red Shoes (1948) because it’s a movie that seems to change the way an audience experiences cinema. A story about a diverse group of individuals collaborating to make art, the film is itself a wonderful example of the process.

As any archaeologist knows, digging up a sarcophagus is a nailbiting business. How small are the chances that inside the shredded linen wrappings will lie a recognisable body with some vestiges of its former life upon it?

Enough DNA and bone to reconstruct the person's age, state of health, status – perhaps even enough detail on the face to bring the dead features back to life and a guess at personality? Properly mummified, a human body can yield an extraordinary amount of living information after thousands of years. But ballets vanish far quicker.

Popular musicians “going classical” can work well. Look at Radiohead’s Jonny Greenwood, at Richard Reed Parry and Colin Stetson from Arcade Fire, or at the late Jóhann Jóhannsson who had a successful career as indie and electronic musician in Iceland before becoming a globally beloved orchestral composer. Of course the boundaries are flimsy anyway these days, with the likes of Max Richter, Nils Frahm and Anna Meredith existing comfortably with one foot in the concert hall and one in the gig venue.

So there’s this prince, see, and he’s not at all happy. For a start, he never got over losing a parent when he was a child. He’s at odds with the world, sick to death with royal protocol and convinced that no one understands him. Worse, having too much time on his hands, he suffers from delusions. Meet Prince Siegfried, who found his soulmate, and met his nemesis, on a moonlit night by a lake.

Edgar Degas is famous for his depictions of ballet dancers. His drawings, paintings and sculptures of young girls clad in the uniform of the dance are signs of an artistic obsession that spanned a remarkable artistic career. One work in particular – a sculpture of a young ballet dancer in a rest position – cemented his reputation as a pioneering spirit, unafraid of provoking controversy in the pursuit of perfection.

“That’s Marcelino Sambé, he’s wonderful,” said the artistic administrator of the Royal Ballet as I followed her down one of the many corridors that weave throughout the Royal Opera House in Covent Garden. “He’s a newly promoted Principal, a very special talent indeed!” I looked over my shoulder at the figure disappearing through some doors.

It’s unlikely that Lord Byron would recognise much about Le Corsaire. Beyond the characters’ names and the Ottoman location, there is little trace of the 1814 bestselling verse-novel on whose fame the ballet hitched a ride. Its plot is very silly indeed – a tale of abducted slave girls and piratical derring-do with added 19th-century ballet tropes of poisoned flowers and opium-induced dreams, not to mention a shipwreck in the final three minutes.

Why is Alexei Ratmansky one of the greatest living choreographers of classical ballet? Well partly because, as last night's performance of The Bright Stream by the Bolshoi at the Royal Opera House proved, he can do comedy.
