"Well could he ride, and often men would say, "That horse his mettle from his rider takes: Proud of subjection, noble by the sway, What rounds, what bounds, what course, what stop he makes!" And controversy hence a question takes, Whether the horse by him became his deed, Or he his manage by the well-doing steed."
