Francesco Cavalli succeeded Monteverdi as the most influential composer of the new genre of opera that emerged in mid-17th-century Venice. Il Xerse is a fictitious dramma per musica that tells of Persian King Xerxes' love for Romilda, who in turn is in love with his brother Arsamene. The plot is an entertaining and extremely intricate human comedy of crossed loves, court intrigues and disguises - the work's popularity saw it staged in Paris at the wedding of Louis XIV and Maria Theresa of Spain. Since overshadowed by Handel's later Xerxes, this Martina Franca production is the first in modern times.
