Diogenes of Babylon

Greek Stoic philosopher — head of the Stoic school after Chrysippus — who was part of the Athenian embassy to Rome in 155 BCE that introduced Greek philosophy to Rome, alongside the Skeptic Carneades and the Academic Critolaus.

Represents the transmission of Stoicism from Athens to Rome — the 155 BCE philosophical embassy is the decisive moment when Greek philosophy entered Roman culture — and his debate with Carneades (who argued both for and against justice on consecutive days) scandalized Rome while demonstrating philosophy's power.
