And since geometry is the right foundation of all painting, I have decided to teach its rudiments and principles to all youngsters eager for art. . .

Art is embedded in nature and they who can extract it, have it.

Some think that they know everybody, but they really don't know themselves.

The artist is chosen by God to fulfill his commands and must never be overwhelmed by public opinion.

As I grew older, I realized that it was much better to insist on the genuine forms of nature, for simplicity is the greatest adornment of art.

If a man devotes himself to art, much evil is avoided that happens otherwise if one is idle.

Love and delight are better teachers than compulsion.
