Armi`da, a beautiful enchantress in 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 Almida Palace, in which she enchanted Rinaldo, has become a synonym for any merely visionary but enchanting palace of pleasure.
