I do not think that Don Quixote would have been as successful without his horse, Rocinante. The horse was a large part of his adventure and the story would not have been complete for him without a horse. He viewed the horse as being such a major part of the “hero” or “knight” persona that was prevalent in the culture of his lifetime. A knight cannot truly succeed without his horse for both protection and his main source of transportation. The relationship he has with his horse allowed him to trust the horse completely which led to success throughout the tale.
