In 155 BCE a delegation of three Greek philosophers arrived in Rome on a political mission (to negotiate the settlement of war fines). During their stay they succeeded in raising Greek philosophy to prominent attention and seeding its future important role in Rome. This is one summary (from SEP):
In 155 BCE Athens sent a delegation of three philosophers (Stoic, Academic skeptic, and Peripatetic) on an embassy to Rome. Their teachings caused a sensation among the educated. The Skeptic Carneades addressed a crowd of thousands on one day and argued that justice was a genuine good in its own right. The next day he argued against the proposition that it was in an agent's interest to be just in terms every bit as convincing.
Is there a canonical primary source (or recommended secondary source) that covers this significant event in the history of ideas in detail?
