Unlike sculptures done by his predecessors, these focus on specific points of narrative tension in the stories they are trying to tell: Aeneas and his family fleeing the burning Troy; the instant that Pluto finally grasps the hunted Persephone; the precise moment that Apollo sees his beloved Daphne begin her transformation into a tree. They are transitory but dramatic powerful moments in each story. Bernini's "David" is another stirring example of this. Michelangelo's motionless, idealized "David" shows the subject holding a rock in one hand and a sling in the other, contemplating the battle; similarly immobile versions by other Renaissance artists, including Donatello's, show the subject in his triumph after the battle with Goliath. Bernini illustrates David during his active combat with the giant, as he twists his body to catapult toward Goliath. To emphasize these moments, and to ensure that they were appreciated by the viewer, Bernini designed the sculptures with a specific viewpoint in mind. Their original placements within the Villa Borghese were against walls so that the viewers' first view was the dramatic moment of the narrative.
