Gaius Ju- Gaius? No, it's Gaius. I know from Battlestar Galactica. Gaius Julius Caesar was born around 100 BCE to one of Rome's leading families. His birth was somewhat miraculous, requiring a surgical procedure that we know today as a Caesar-ian section. Coming as he did from the senatorial class, it was natural that Caesar would serve in both the army and the senate, which he did. He rose through the ranks.
