“The mountains, too, at a distance appear airy masses and smooth, but seen near at hand, they are rough.”

“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.”

“It’s possible, I’m moving through the hard veins of heavy mountains, like an arc, alone; I’m so deep inside, I see no end in sight, and no distance: everything is getting near and everything near is turning to stone.”

“A scrip on my back, and a staff in my hand,
I march on in haste through an enemy's land;
The road may be rough, but it cannot be long;
And I'll smooth it with hope, and I'll cheer it with song.”

“Chaos, a rough and unordered mass.”
Chaos, rudis indigestaque moles.

“Up the airy mountain,
Down the rushy glen,
We daren't go a-hunting,
For fear of little men.”

“Near me, nothing but distances.”

“As a general rule, therefore, the lights and shadows of clouds near the horizon are less vivid than in clouds higher up. Exceptions to this rough rule will be found when the source of light is near the horizon, as in sunset and sunrise, also when there is a gathering of local stormclouds which may hover over the distance as a dark pall, when there is fair weather and light, transparent clouds near to us.”

“This part of optics, when well understood, shows us how we may make things a very long distance off appear as if placed very close, and large near things appear very small, and how we may make small things placed at a distance appear any size we want, so that it may be possible for us to read the smallest letters at incredible distances, or to count sand, or seed, or any sort of minute objects.”

“Blue, green, grey, white, or black; smooth, ruffled, or mountainous; that ocean is not silent.”
