Problem: Extract the answer to the question from the following context. Question: What must adhere to the rules of visual language? Context: The earliest examples of visual representations in Iranian history are traced back to the bas-reliefs of Persepolis, c. 500 BC. Persepolis was the ritual center of the ancient kingdom of Achaemenids, and the figures at Persepolis remain bound by the rules of grammar and syntax of visual language. The Iranian visual arts reached a pinnacle by the Sassanid Era. A bas-relief from this period in Taq Bostan depicts a complex hunting scene. Similar works from the period have been found to articulate movements and actions in a highly sophisticated manner. It is even possible to see a progenitor of the cinema close-up in one of these works of art, which shows a wounded wild pig escaping from the hunting ground.

Problem: Extract the answer to the question from the following context. Question: Who did Theodosius inherit from? Context: Augustus' religious reformations raised the funding and public profile of the Vestals. They were given high-status seating at games and theatres. The emperor Claudius appointed them as priestesses to the cult of the deified Livia, wife of Augustus. They seem to have retained their religious and social distinctions well into the 4th century, after political power within the Empire had shifted to the Christians. When the Christian emperor Gratian refused the office of pontifex maximus, he took steps toward the dissolution of the order. His successor Theodosius I extinguished Vesta's sacred fire and vacated her temple.
