This is this first we’ve heard of Octavius Caesar, Julius Caesar’s 19-year-old grand-nephew. As Julius Caesar had no sons, he had been grooming Octavius to be his heir. In his will, Caesar officially adopts Octavius as his son and leaves to him the bulk of his enormous fortune. Octavius has spent many years in Greece being educated, so he’s not well acquainted with the inner workings of Roman politics.
