Errors Accumulate In The Sketch And Compound

Practice By Drawing Things Large, As If Equal In Representation And Reality. In Small Drawings Every Large Weakness Is Easily Hidden; In The Large, The Smallest Weakness Is Easily Seen.

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... Enable Us To Examine... The Work As A Whole... And, Before Continuing Any Further, To Estimate The Likely Trouble And Expense.

I Prefer You To Take As Your Model A Mediocre Sculpture Rather Than An Excellent Painting, For From Painted Objects We Train Our Hand Only To Make A Likeness, Whereas From Sculptures We Learn To Represent Both Likeness And Correct Incidence Of Light.

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

There Is No Art Which Has Not Had Its Beginnings In Things Full Of Errors. Nothing Is At The Same Time Both New And Perfect.
