Maya Plisetskaya, a ballerina regarded as one of the greatest of the 20th Century, has died aged 89.
Bolshoi director Vladimir Urin told the state news agency Tass that Plisetskaya died in Germany of a heart attack on Saturday.
President Vladimir Putin issued a message of condolence and tributes came from across the dance world.
Plisetskaya was renowned for intense performances that contrasted with the ethereal style of many other dancers, especially in Tchaikovsky's Swan Lake.
Plisetskaya joined the Bolshoi troupe in 1943 at the age of 18 and stayed until 1990 when she left amid disputes with its director.
However, she returned to its stage for gala appearances, including a 75th birthday performance in 2000.
She is survived by her husband, composer Rodion Shchedrin.
Pavel Dmitrichenko, the ballet dancer accused of organising an attack that nearly blinded the Russian Bolshoi Ballet's artistic director, has been convicted of the crime by a Russian court.
Mr Dmitrichenko was convicted alongside two co-defendants,
The dancer had claimed that he told an alleged accomplice to beat up the director but not to throw acid.
