It is true that Donatello, who afterwards did the ornamentation of the other organ opposite this one, displayed much more judgment and skill than Luca, as will be said in the proper place, because he did almost the whole of the work in the rough as it were, not delicately finishing it, so that it should appear much better at a distance than Luca's; as it does, for with all his care and skill the eye cannot appreciate it well because of the very polish and finish, which are lost in the distance, as it can the almost purely rough hewn work of Donato. To this matter artists should devote much attention, because experience shows that all things seen at a distance, whether they be paintings or sculptures or any other like thing, are bolder and more vigorous in appearance if skilfully hewn in the rough than if they are carefully finished. Besides the effect obtained by distance, it often happens that these rough sketches, which are born in an instant in the heat of inspiration, express the idea of their author in a few strokes, while on the other hand too much effort and diligence sometimes sap the vitality and powers of those who never know when to leave off.
