It Was Never Shameful To Learn From Any Teacher Things That Are Useful To Know.

I Will Never Tire Of Recommending The Custom, Practiced By The Best Architects, Of Preparing Not Only Drawings And Sketches, But Also Models Of Wood Or Any Other Material. These...

I Certainly Consider A Great Appreciation Of Painting To Be The Best Indication Of A Most Perfect Mind.

A Common Error Of Ignorance Is To Maintain That What One Does Not Know Does Not Exist.
