What sculptural conventions did Michelangelo use for the figure of Moses in order to create an expression of awful wrath?

Michelangelo employed several sculptural conventions to convey the expression of awful wrath in his depiction of Moses. He emphasized the figure's muscularity and dynamic posture, with tense limbs and a furrowed brow that signal intense emotion. The intricate detailing of the face, particularly the deep-set eyes and pronounced beard, further enhances the sense of fury and power. Additionally, the dramatic contrasts of light and shadow, achieved through his mastery of chiaroscuro, amplify the menacing aura surrounding Moses.
