The process was completed in 27 BC when the Roman Emperor Augustus annexed the rest of Greece and constituted it as the senatorial province of Achaea. Despite their military superiority, the Romans admired and became heavily influenced by the achievements of Greek culture, hence Horace's famous statement: Graecia capta ferum victorem cepit ("Greece, although captured, took its wild conqueror captive"). The epics of Homer inspired the Aeneid of Virgil, and authors such as Seneca the younger wrote using Greek styles. Roman heroes such as Scipio Africanus, tended to study philosophy and regarded Greek culture and science as an example to be followed. Similarly, most Roman emperors maintained an admiration for things Greek in nature. The Roman Emperor Nero visited Greece in AD 66, and performed at the Ancient Olympic Games, despite the rules against non-Greek participation. Hadrian was also particularly fond of the Greeks; before he became emperor he served as an eponymous archon of Athens.
