" And Lancelot followed her with his eyes and heart until she reached the door; but she was not long in sight, for the room was close by. His eyes would gladly have followed her, had that been possible; but the heart, which is more lordly and masterful in its strength, went through the door after her, while the eyes remained behind weeping with the body. "

― Chrétien de Troyes , Lancelot: The Knight of the Cart
