When first looking at the painting, I was immediately drawn to the boy, David. His right arm, leg, and torso are shown in a beautiful light. David represents good and triumph. In contrast, Goliath is shown in almost complete darkness. Even though a slight amount of light is shown on his face, he is still seen as dark and evil. The positioning of their bodies is also significant. David has his left knee on Goliath’s chest and hovering over his body while fastening Goliath’s head by the hair. This is complete victory and domination over Goliath. The painting portrays the rise of good and the fall of evil.
