En direct, Vidéo: Rechercher des critiques de musique classique, opéra et ballet | Clare Shearer

If you've been brought up with the Judaeo-Christian ideal of an all-powerful, all-good God, Norse mythology can come as a bit of a shock. Wotan, the father of the gods, is philandering, deceitful, power-hungry, sentimental, violent and ultimately weak - the gamut of human frailties writ large.

As The Flying Dutchman nears its close, the crew of Daland's ship are celebrating their safe homecoming and yelling at the Dutchman's unseen crew to join them. To their horror, they realise that they have indeed woken the dead: the Dutchman's crew are ghosts who have wandered the oceans for centuries: the storms cannot burst their sails for they are protected by Satan.
