Plutarch (later named, upon becoming a Roman citizen, Lucius Mestrius Plutarchus; AD 46–AD 120) was a Greek historian, biographer, and essayist, known primarily for his Parallel Lives and Moralia. He is classified as a Middle Platonist. Plutarch's surviving works were written in Greek, but intended for both Greek and Roman readers.
This was a great follow up to reading the Rubicon as it helped to portray the events of the fall of the roman republic from the perspective of what it meant for the various men involved in it. This translation is also very readable and actually quite entertaining (although I caught myself zoning out a little in battle descriptions). The little introductions to each section were also very helpful in positioning the historical perspective and bias of Plutarch, keeping in mind when he was writing and the sources he consulted.
