The insatiable spirit and the unparal-leled genius of Leonardo Da Vinci give radiance to this biographical romance. The heroic grandeur of Leonardo's achievements in art and science, the fecundity of his mind and the illimitable reaches of his imagination are revealed against the glowing background of the Renaissance. Kings and popes and courtiers, artists and philosophers and poets throng the scene. Dominating them all is Leonardo in a portrait that might have been wrought by one of his own contemporaries.
