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. . .

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

No single man can be taken as a model for a perfect figure, for no man lives on earth who is endowed with the whole of beauty.

Geometry is the foundation of all painting.

Why has God given me such magnificent talent? It is a curse as well as a great blessing.

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

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