In his letter to Theo, from Cuesmes, 24 September 1880 - original manuscript of letter no. 158 - at Van Gogh Museum, location Amsterdam - inv. no. b156 V/1962, http://vangoghletters.org/vg/letters/let158/letter.html
Van Gogh's copies (drawings) he made after the work of Rousseau have been lost
1880s, 1880
Context: First and foremost, the masterly etching, 'The bush', by Daubigny/Ruisdael. [ Daubigny's etching 'The bush', he made after Jacob van Ruisdael ].... I plan to do two drawings, either in sepia or something else, one of them after this etching [by Daubigny] — the other [etching, made] after T. Rousseau's 'The oven in Les Landes'. This latter sepia is already done — it's true — but if you compare it with Daubigny's etching, you'll understand that it becomes weak, even though the sepia drawing considered on its own may very well have a certain tone and sentiment. I have to go back to it and work on it again.... I couldn't tell you how happy I feel to have taken up drawing again. It had already been on my mind for a long time, but I always saw the thing as impossible and beyond my reach.
“It may not sound very consistent with any such professed humility on my part, if I say to you that, after having served for the Quaternions during fourteen years, and having (as America seems to think) won my Rachel—to be my own by an intellectual marriage—I now wish to wind up several scientific projects, from which those quaternions had for a long time diverted me; and feel as if I were entering, or had already entered, on a new harvest of labour and reputation. As to Fame, if it have not been won or earned already, it is not likely that any future exertion will make it mine.
But as to the Labour; that is a thing within everybody's power to judge of, even for himself. I have very long admired Ptolemy's description of his great astronomical Master, Hipparchus… "a labour-loving and truth-loving man."—Be such my epitaph!”

Context: The word fractal, once introduced, had an extraordinary integrating effect upon myself and upon many people around. Initially again it was simply a word to write a book about, but once a word exists one begins to try to define it, even though initially it was simply something very subjective and indicating my field. Now the main property of all fractals, put in very loose terms, is that each part — they're made of parts — each part is like the whole except it is smaller. After having coined this word I sorted my own research over a very long period of time and I realised that I had been doing almost nothing else in my life.
