The plot is loosely based on the story of Jason and the Golden Fleece, but the opera contains many comic elements too. This 2010 production from Antwerp is orchestrated and conducted by the internationally reputed baroque specialist Federico Maria Sardelli. It is directed by the young Frenchwoman Mariame Clément, who is currently making a name for herself with her infectious directing in German and French opera houses. The title role is sung by the promising French countertenor Christophe Dumaux.
