" Poetry is the Path on the Rainbow by which the soul climbs; it lays hold on the Friend of the Soul of Man. Such exalted states are held to be protective and curative. Medicine men sing for their patients, and, in times of war, wives gather around the Chief's woman and sing for the success of their warriors. "Calling on Zeus by the names of Victory" as Euripides puts it. "
