Augustan and Julio-Claudian art
Augustan and Julio-Claudian art is the artistic production that took place in the Roman Empire under the reign of Augustus and the Julio-Claudian dynasty, lasting from 44 BC to 69 AD. At that time Roman art developed towards a serene "neoclassicism", which reflected the political aims of Augustus and the Pax Romana, aimed at building a solid and idealized image of the empire. The art of the age of Augustus is characterized by refinement and elegance, adapted to the sobriety and measure that Augustus had imposed on himself and his court.
