OpenAI's Answer
Based on the search results, it appears there is some confusion regarding the historical figure "Gaius Novellius Octavianus" at the beginning of the third century.
However, I found information on Gaius Julius Caesar Augustus, originally known as Gaius Octavius, who was a significant Roman figure but lived much earlier. He was the founder of the Roman Empire and reigned as the first Roman emperor from 27 BC until AD 14 (source). There is no record indicating the existence of a prominent figure named "Gaius Novellius Octavianus" from the early third century based on available information.
Please let me know if you meant a different historical figure or if there's anything else you need assistance with!
