In the French epic "The Song of Roland", Olivier was the title character's closest friend, advisor, and confidant. Whereas Roland was portrayed as recklessly courageous, Olivier was said to exhibit poise and wisdom in combat. In the legend, Olivier was fatally impaled from behind by the lance of Algalif. Before dying, however, he used his sword, "Hauteclere" to split his attacker's head open with one blow. It is not known if, like Roland, Olivier is based upon a real historical figure.
