Vivaldi: Oracolo In Messenia - Julia Lezhneva L Oracolo in Messenia, an opera written by Vivaldi for Vienna in 1740, was reconstructed by Fabio Biondi in 2011 in a triumpan open to the famous Resonanzen festival in Vienna, appropriately enough. Originally, the opera was intended to be performed in Vienna during Carnival in 1741, but due to the death of the Austrian Emperor and ultimately, himself, his plans fell through. Vivaldi expert, Fabio Biondi, reconstructed the work using a recently discovered libretto in the Library of Congress, Viavaldi s personal scores as well as those from his contemporaries.
