Vincenzo Petrali

Sophonisba was a Carthaginian noblewoman who lived during the Second Punic War, and the daughter of Hasdrubal Gisco. She held influence over the Numidian political landscape, convincing king Syphax to change sides during the war, and later, in an act that became legendary, she poisoned herself rather than be humiliated in a Roman triumph.
