In the Song of Roland, Naimon supports Ganelon's proposal to make peace with King Marsile. He does not suspect Ganelon's treachery. Later, he organizes the divisions of Charlemagne's army and participates in the battle against Baligant.
This same Naimon, the traditional adviser of the king, this medieval Nestor, this uncompromising advocate of Right against Might, is the most unchanging figure among the heroes. He is the embodiment of good sense, moderation and justice.
