Alfredo Casella
The resurrection of Vivaldi's unpublished works in the 20th century is mostly due to the efforts of Alfredo Casella, who in 1939 organized the historic Vivaldi Week, in which the rediscovered Gloria (RV 589) and l'Olimpiade were revived. Since World War II, Vivaldi's compositions have enjoyed wide success. Historically informed performances, often on "original instruments", have increased Vivaldi's fame still further.
