One part of a picture ought to be like the first part of a tune, that you guess what follows, and that makes the second part of the tune, and so I'm … - Thomas Gainsborough

Do you consider, my dear maggotty sir [cosy-name for his friend], what a deal of work history pictures require to what little dirty subjects of coal horses and jackasses and such figures as I fill up with; no, you don't consider anything about that part of the story.. .But to be serious (as I know you love to be), do you really think that a regular composition in the Landskip [landscape] way should ever be filled with History, or any figures but such as fill a place (I won't say stop a gap) or create a little business for the eye to be drawn from the trees in order to return to them with more glee.

You please me much by saying that no other fault [in the portrait Gainsborough recently made and sent] is to be found in your picture than the roughness of the surface; for that part being of use in giving force to the effect at a proper distance.. ..I urn [earn?] much better pleased that they should spy out things of that kind than to see an eye half an inch out of its place or a nose out of drawing when view'd at a proper distance. I don't think it would be more ridiculous for a person to put his nose close to the canvas and say the colours smell offensive than to say how rough the paint lies; for one is just as material as the other with regard to hurting the effect and drawing of a picture. For Sir Godfrey Kneller used to tell them that pictures were not made to smell of..

It is my strict charge that after my decease no plaster cast, model, or likeness whatever be permitted to be taken. - 'Tho. Gainsborough'.
