Gaius Maecenas
Hoping to continue Octavius’ education, at the end of 45 BC Caesar sent him, along with his friends Agrippa, Gaius Maecenas, and Quintus Salvidienus Rufus, to Apollonia in Macedonia. There, Octavius learned not only academics and self-control but military doctrine and tactics as well. Caesar, however, had more than just education in mind for Octavius. Macedonia was home of five legions and he hoped to use it as a launching ground for an upcoming war with Parthia in the Middle East. In preparation, Caesar had nominated Octavius to serve as Master of the Horse (Caesar’s chief lieutenant) for the year 43 BC, thus making Octavius the number-two man in the state at the age of 19.
