Athens sent to Rome an embassy composed of the heads of three major philosophical schools: Carneades the Academician, Diogenes the Stoic and Critolaus the Peripatetic. The delegation's original motive was to negotiate with the Roman senate the reduction of a fine imposed on Athens, but the lectures given there by the philosophers also made such an impression on their Roman audience that created an atmosphere of both enthusiasm and scandal in the capital.
