A Prague festival will host the world premiere of Antonio Vivaldi's opera
L'Unione della Pace, e di Marte, following its reconstruction by a Czech
expert 284 years after its only performance. The serenata was composed for
the birth of French King Louis XV's first children, twin sisters Louise
Elisabeth and Anne Henriette and was performed only once, in 1727, in the
open air, in a garden adjacent to the church of Madonna dell'Orto in
Venice. The complete libretto has been preserved in the National Braidense
Library in Milan, but the score disappeared altogether and had to be
reconstructed on the basis of tunes from Vivaldi's other operas. The
international ensemble Hof-Musici, led by composer and conductor Ondrej
Macek will perform L'Unione della Pace, e di Marte several times within the
Prague Baroque Festival starting on June 17. The premiere is scheduled for
July 4 at the Ledebour Garden at the foot of Prague Castle.
