Genius is infinite painstaking.

If people knew how hard I worked at my art, they would not consider me a genius.

No great work of art is ever finished.

Every beauty which is seen here by persons of perception resembles more than anything else that celestial source from which we all are come.

It is not sufficient merely to be a great master in painting and very wise, but I think that it is necessary for the painter to be very moral in his mode of life, or even, if such were possible, a saint, so that the Holy Spirit may inspire his intellect.

The science of design, or of line-drawing, if you like to use this term, is the source and very essence of painting, sculpture, architecture... Sometimes... it seems to me that... all the works of the human brain and hand are either design itself or a branch of that art.

If there is some good in me, it is because I was born in the subtle atmosphere of your country of Arezzo. Along with the milk of my nurse I received the knack of handling chisel and hammer, with which I make my figures.
