This is a very readable biography that makes full use of the remarkably well-documented sources describing (elephants and all) this slice of the early years of the Roman Empire.
The Carthaginian general Hannibal Barca (d. 183 BCE at the age of 64) was one of the great military commanders of the ancient Mediterranean world. From start to finish, he is a good match for an NPA+ type.
Hannibal was above all a dynamic individual and a soldier's soldier. According to the Roman historian, Livy, Hannibal was known for his "intense expression and penetrating gaze"... "Never before was there a more suited genius for commanding respect and obedience from his men".
In addition, he shunned flamboyance and wore the same clothes as his men. He is known to have married once and had no reputation of illicit relationships with other women. Although his detractors leveled plenty of accusations of cruelty and brutality against him, actually he was quite lenient with captives and on several occasions went out of his way to give a proper burial to a defeated Roman commander who was killed in battle.
After his military career was over (he was finally defeated by the Romans), he was elected to office where he served as a dynamic politician, involving himself in progressive causes. There is a story in which a dissenter on the podium so enraged him that Hannibal leaped forward and dragged the speaker away... "When Hannibal's indignant fellow Carthaginians objected to his physical aggression, his verbal response was both an apology for being away so many years and for behaving more as a military leader before the council than a legislator" (p. 244).
