Vivaldi work revived 278 years on

A long-lost opera by the Italian composer Antonio Vivaldi has been performed for the first time in 278 years, in the city of Prague. Argippo was written for the Czech capital and premiered there in 1730. But the opera - a tale of "passion, love and trickery" in an Indian maharaja's court - later disappeared without trace. Most of the score was discovered in Germany by a young Czech musician who completed the missing parts.
