Pina Bausch decided: “Words can’t do more than just evoke things - that’s where dance comes in.” Well, up to a point, Lord Copper. Only if they’re bad words and good dance - bad writhing instead of, say, Shakespeare’s words isn’t much of a swap. But with Bausch, people tended to hang on every word, probably because so much of her dance was indeed pretty damn good, and it’s so difficult to put into words just why that was.

There is a moment when you see dancers at their absolute peak that notches a bit of history in your memory - you never forget when you see it happen. In my area of contemporary choreography you can’t measure it in those terms but you can with classical ballet, and a Don Quixote performance like I saw at the Bolshoi last night sets the bar. This level of performance is Olympic-sized, it erases everything else you have seen.

After all the encomia for Natalia Osipova it’s time for a paean to another Bolshoi ballerina, whose witty underplaying and conquest of style makes her the lady I’d choose to see shipwrecked in full tutu, diamonds and pink satin pointe shoes on any desert island I fetched up on. Maria Alexandrova starred in two 19th-century restorations of palatial opulence - the pirate party Le Corsaire and the princess party Paquita.

We’re getting used to expecting the extraordinary from Natalia Osipova - and then getting some more. With her impish face and farouche capriciousness, with a spring like a high-jumper and shoulders like a swimmer, she is without doubt the most explosively delightful comedienne and virtuoso around at the Bolshoi, but could she be a Giselle? A weak-hearted innocent, a sorrowing ghost, an angel of pleading mercy? Doubt it not.

Coppélia is the name of the doll in the ballet-comedy - not that of the heroine, who is a bad pixie named Swanilda, a girl of youthful capriciousness but a heart of gold.
