★★★★½
(Glyndebourne, conducted by William Christie, 17 May 2017)
King Danao of Argos is troubled. His brother’s Egyptian troops have gathered on his border, forcing him to suggest a diplomatic match to avoid conflict. His fifty daughters will marry his brother’s fifty sons in a mass ceremony, cementing a peace treaty between the two nations. But Danao has given his daughters secret instructions. The Oracle at Delphi has warned him that one of his nephews will rob him of his life and kingdom. And so each of the fifty girls has been ordered to murder her husband on their wedding night. Each of them obeys. Except one: Hipermestra, who loves her new husband, her cousin Linceo, and urges him to escape. Her compassion will be rewarded by a tide of blood. In this thrilling premiere of an all-but-forgotten opera by Francesco Cavalli, Glyndebourne have updated an ancient story to a setting in the modern Middle East, giving it a punch that lingers long after the final curtain comes down.
