I'm struggling with flowering trees [in Spring 1881, shortly after his Algeria trip] and with women and children. I keep feeling regretful, all the s… - Pierre-Auguste Renoir

What I like so much about Corot is that he can say everything with a bit of tree; and it was Corot himself that I found [back] in the museum of Naples – in the simplicity of the work of Pompeii and the Egyptians. These priestesses in their silver-grey tunics are just like Corot's nymphs.

I studied a good deal in the museum at Naples; the Pompeian paintings are extremely interesting from every aspect. So I am staying in the sun – not to paint portraits but while I am warming myself and looking hard at things I hope I will have acquired some of the grandeur and simplicity of the old masters. Raphael didn't work out-of-doors, but he studied the sunlight all the same – his frescoes are full of it. So, by looking around outside, I have finished by seeing only the broad harmonies, and am no longer preoccupied with the little details, which only extinguish the sunlight, instead of increasing its brilliance. I hope therefore, when I get back to Paris, to produce something which will be the outcome of all these general studies, and to give you the benefit of them [in a letter written during his three-weeks-stay, working with Paul Cezanne at l'Estaque, near Marseille]

One morning one of us had run out of black; and that was the birth of Impressionism.
