Horses with balletic names have a fine tradition, despite prince Nureyev. I got most of this from Thoroughbred Times website.
Northern Dancer (1961-1990) can count at least ten sons as truly outstanding sires including Nijinsky II, Nureyev and Sadler’s Wells.
Nijinsky II was Northern Dancer’s first-and best-international champion. Winner of the first 11 races of his 13-start career. Not long after his death in 1992, he surpassed his sire’s record for stakes winners, with a career total of 155 stakes winners from 862 foals .
Nureyev (died 1990), the top-priced yearling of his year, finished first in his three starts, culminating in the 1980 Two Thousand Guineas. Though he lost that race in the stewards’ room and never ran again because of a wind infirmity, Nureyev proved his brilliance. He sired Theatrical and Fadeyev.
Sadler’s Wells has become Northern Dancer’s most dominant son at stud. Sire of a long succession of top-class milers and middle-distance horses, Sadler’s Wells has led the English sire list a modern record 12 times and French list four times.
Diaghilev, by Sadler's Wells, is the most expensive horse ever sold at public auction in Europe, having cost £3.57 million as a yearling 3 years ago. Last year at Ascot he failed to match his form & seems to have lost favour. His name is now River Dancer & seems to have moved Downunder. There is another horse called Diaghilev in Germany, a dressage colt.
There's an Australian racehorse called Lady Pavlova.
I couldnt' find a horse called Ballerina in Google, but found this cute little story, http://www.thereporter.com/Current/Columnists/Moy/moysun100602.html,
called 'A horse ballerina, of course, of course'.
Quote: "My big problem now is how to make the tutu so it doesn't irritate Tyler. If I tie it behind the saddle and across his back, it could make him buck. This would not be appropriate for a ballerina."
