‘Perhaps the best of all my works’, said Gluck of his Armide. But this, the fifth of his seven ‘reform operas’, has never quite captured the public interest as have Orfeo, Alceste, the two Iphigenies and even Paride ed Elena. Unlike those works it is based not on classical mythology but on Tasso’s crusade epic, Gerusalemme liberata. No doubt Gluck turned to this libretto, originally written by Quinault, to challenge Parisian taste by inviting comparison with the much-loved Lully setting. Its plot is thinnish, concerned only with the love of the pagan sorceress Armide, princess of Damascus, for the Christian knight and hero Renaud, and his enchantment and finally his disenchantment and his abandonment of her; the secondary characters have no real life.
