To preserve the sense of the 'grey' even in the most powerful green is amazingly difficult and whoever discovers it will be a happy mortal. (translat… - Gerard Bilders

The moon appeared for some time [in the Savoy, Switzerland] and the rocks seemed to be much bigger than they were. The mountains were silvery illuminated and appeared gently against the mysterious blue of the sky - that blue color with moonlight, that has such an indefinable, deep tone; actually it is not a blue.

I have seen pictures [on the Salon of Brussel, 1860], of which I had never dreamed and in which I found all that my heart desires, all that I nearly always miss in the Dutch painters. Troyon, Courbet, Diaz, Dupré [all painters of the School of Barbizon, Robert Fleury have made a great impression on me. I am a good Frenchman, therefore; but, as Simon van den Berg says, it is just because I am a good Frenchman that I am a good Dutchman, since the great Frenchmen of today and the great Dutchmen of the past have much in common. Unity, restfulness, earnestness and, above all, an inexplicable intimacy with nature are what struck me most in these pictures. There were certainly also a few good Dutch pieces, but, generally speaking, when you place them next to the great Parisians, they lack that mellowness, that quality which, so to speak, resembles the deep tones of an organ. And yet this luxurious manner came originally from Holland, from our steaming, fat-coloured Holland! They were courageous pictures; there was a heart and a soul in them.

If you ever want to see the 'Nightwatch' [by Rembrandt ] at its best, visit it at two o'clock, half past three afternoon.. ..that time a warm light falls on the painting [then located in the Trippenhuis in Amsterdam]; another world opens, a world of glow, light and inimitable power. I think Rembrandt is not only beautiful, but – were we still in the Age of the old Gods, I would worship him. You can lose yourself in that painting; it is a complete abyss, deep and sky-high.. ..then suddenly I think of my own paintings - poor cow, dairy, and sheep compositions, and I doubt, will I ever become something..
