Ferrando, captain of the guard, rouses the soldiers resting in the guardroom. They are under orders of Count di Luna to keep watch for a troubadour who serenades Leonora, the queen’s lady-in-waiting, with whom the Count is also in love. Ferrando keeps the men awake by telling them the story of a baby, the Count’s brother: many years before, a gypsy had been burned at the stake for supposedly casting a spell on the baby. In revenge, the gypsy’s daughter stole the child. Later an infant’s bones – presumably those of the Count’s brother – were found in the ashes. Legend has it that the gypsy’s ghost still haunts the castle.
