Envoys

"One Musonius Rufus, a man of equestrian rank, strongly attached to the pursuit of philosophy and to the tenets of the Stoics, had joined the envoys. He mingled with the troops, and enlarging on the blessings of peace and the perils of war, began to admonish the armed crowd. Many thought it ridiculous; more thought it tiresome; some were ready to throw him down and trample him under foot, had he not yielded to the warnings of the more orderly and the threats of others, and ceased to display his ill-timed wisdom."

Tacitus, Histories, (100 AD).
