I am busy working on a large painting with sheep; the last days I am working with real pleasure, the weather is.. ..not too hot and with nice skies. … - Anton Mauve

At first I did not feel much inclined to agree [ Willem Maris had asked Mauve to paint together in open air, around the village Oosterbeek, c. 1863], but I did not like to refuse the little fellow flatly, so we went off together. My companion did not suffer from loquacity; and, coming to a field with cows in it, I sat down to go on with a drawing which I had begun that morning. The little chap [Willem Maris] strolled around a bit and then settled down to work himself. We sat there for hours under the pollards, until I grew curious to see what the little fellow was at. He sat sketching with a bit of chalk; but, oh! I stood astounded. I seized him by the hand and stammered in my turn, 'My boy, what an artist you are! You stagger me! It's magnificent!'

(version in original Dutch / origineel citaat van Anton Mauve, in het Nederlands:) Neem toch een voorbeeld aan de Hollandse zeventiende-eeuwse meesters, we moeten kijken naar het land om ons heen zoals de oude meesters dat deden.

Come on, don't wait, come! Or don't you like to roll into the lush grass? I really would like to be completely a cow, to feel in that way the childish fun that such a beast gets when it is running about in the pasture and makes all that kind of silly jumps with its tail high in the air.
