ガイウス・ラエリウス
Probably through Gaius Laelius, who had attended the lectures of Diogenes and then of Panaetius, he was introduced to Scipio Aemilianus and, like Polybius before him, gained his friendship. Both Panaetius and Polybius accompanied him on the Roman embassy that Scipio headed to the principal monarchs and polities of the Hellenistic east in 139-138 BC. Along with Polybius, he became a member of the Scipionic Circle.
