The High Priest takes the King's young son Aznra, and hides him, and fifteen years later brings him forth and presents him to the populace, which greets him with acclamation and moves on the palace to avenge the death of the King. Prince Canach cravenly hides when the Queen bids him lead the royal guard against the mob, and she dons his armor and takes his place at the head of the troops. A sensational battle takes place .reaching its height on the steps of the palace. Azura singles out, as he thinks, Prince Canach and when his opponent falls mortally wounded he finds it was his own mother.
