Describe and analyze the iconography of Augustus of Primaporta. What was the sculpture's possible function?

What will be an ideal response?

The ideal Answer should include:
1. Augustus of Primaporta was inspired by heroic Greek figures, such as Polykleitos's Spear Bearer, and portrays the ruler in the prime of his youth.
2. However, the naturalistic details of the sculpture make him easily recognizable and might correspond to the emperor's use of portraiture for political propaganda.
3. Augustus wears a cuirass that depicts defeated barbarians and scenes of his military victories.
4. Augustus is shown with bare feet, which led some scholars to propose that the sculpture was made after his death to commemorate his apotheosis, or elevation to divine status.
