His father orders Juan to rub this liquid over his body after he is dead, saying that it will restore him to life, and make him young again.
He also chooses the Abbot of San-Lucar to be the confessor of his wife and son, and Felipe is raised to be religiously devout.
On Juan's death bed, he tells his son Felipe about the phial of liquid, claiming that it is holy water.
A shocked Felipe faints, and the phial drops to the floor and breaks and all the rest of the liquid is lost.
People rush into the room when they hear the noise, and see Don Juan's body with the head and one arm bought back to life and youth, and the rest still dead.
The Abbot of San-Lucar claims that the miracle means that Don Juan is to be canonised as a saint.
