Lucius Calpurnius Piso Caesoninus

Roman senator — father-in-law of Julius Caesar — and Epicurean sympathizer who was the target of Cicero's virulent In Pisonem — representing the combination of political power and philosophical materialism that Cicero regarded as the most dangerous Roman type.

Represents the Epicurean in Roman politics — the man who uses Epicurean philosophy to justify pleasure-seeking and withdrawal from civic responsibility — which Cicero attacks as the corruption of philosophy by power.
