The dogeress in revenge invokes the aid of a famous sorceress, who molds a wax image and by the power of witchcraft causes pain to Pantea as the figure is pierced with pins and otherwise tortured. The dogeress in her unreasoning resentment and rage finally decides, through the figure, to burn Pantea, but to her horror discovers that Orseola suffers with her. The lovers are incinerated in a spectacular blaze of fire, and the dogeress, overcome with the enormity of her action, falls lifeless.
