I shall here apply to what is to be called beautiful the same touchstone as that by which we decide what is right. For as what all the world prizeth as right we hold to be right, so what all the world esteemeth beautiful that we will also hold for beautiful, and ourselves strive to produce the like.
There are many causes and varieties of beauty; he that can prove them is so much the more to be trusted.
The accord of one thing with another is beautiful, therefore want of harmony is not beautiful. A real harmony linketh together things unlike.
Use is a part of beauty, whatever therefore is useless unto men is without beauty.
The more imperfection is excluded so much the more doth beauty abide in the work.
Guard thyself from superfluity.
But beauty is so put together in men and so uncertain is our judgment about it, that we may perhaps find two men both beautiful and fair to look upon, and yet neither resembleth the other, in measure or kind, in any single point or part; and so blind is our perception that we shall not understand whether of the two is the more beautiful, and if we give an opinion on the matter it shall lack certainty.
Negro faces are seldom beautiful because of their very flat noses and thick lips; moreover, their shinbone is too prominent, and the knee and foot too long, not so good to look upon as those of the whites; and so also is it with their hand. Howbeit, I have seen some amongst them whose whole bodies have been so well-built and handsome that I never beheld finer figures, nor can I conceive how they might be bettered, so excellent were their arms and all their limbs.
Seeing that man is the worthiest of all creatures, it follows that, in all pictures, the human figure is most frequently employed as a centre of interest. Every animal in the world regards nothing but his own kind, and the same nature is also in men, as every man may perceive in himself.
