Armida is a beautiful enchantress in Torquato Tasso's Jerusalem Delivered, who bewitched Rinaldo, one of the Crusaders, by her charms, as Circe did Ulysses, and who in turn, when the spell was broken, overpowered her by his love and persuaded her to become a Christian. The "Armida Palace" in which she enchanted Rinaldo has become a synonym for any merely visionary but enchanting palace of pleasure.
