My business is to paint what I see, not what I know is there. - J. M. W. Turner

I never in my whole life could make a drawing like that; I would at any time have given one of my little fingers to have made such a one [one of Girtin's yellow drawings].

In our variable climate where [all] the seasons are recognizable in one day, where all the vapoury turbulence involves the face of things, where nature seems to sport in all: her dignity and dispensing incidents for the artist’s study.. ..how happily is the landscape painter situated, how roused by every change in nature in every moment, that allows no languor even in her effects which she places before him, and demands most peremptorily every moment his admiration and investigation, to store his mind with every change of time and place.

Hawkey - Hawkey [Mr. Fawkes of Farnley Hall, North Yorkshire, close friend of Turner] - come here - come here! Look at this thunderstorm! Isn't it grand? - Isn't it wonderful? - Isn't it sublime?. .There, Hawkey; in two years you will see this again, and call it 'Hannibal Crossing the Alps'.
