The Great Use Of Copying, If It

The Distinct Blue, Red, And Yellow Colors... Though They Have Not The Kind Of Harmony Which Is Produced By A Variety Of Broken And Transparent Colors, Have The Effect Of Grandeur.

Nothing Is Denied To Well-directed Labor.

Let Me Recommend To You Not To Have Too Great Dependence On Your Practice Or Memory, However Strong Those Impressions May Have Been Which Are There Deposited. They Are Forever Wearing Out, And Will Be At Least Obliterated, Unless They Are Continually Refreshed And Repaired.

Style In Painting Is The Same As In Writing; A Power Over Materials, Whether Words Or Colors, By Which Conceptions Or Sentiments Are Conveyed.

It Is Vain For Painters... To Endeavour To Invent Without Materials On Which The Mind May Work.
