Monet "brushed quickly at right angles to the protruding threads over a canvas whose weft threads are thicker than its warp. The threads became covered in pigment, but the valleys remained bare. Monet let it dry, then repeated the process...
"...when the next coats were dry [he tipped] the ridges with other colors..."
"...for viewers [the technique] translated into a perception of wavering or twinkling surfaces and barely-perceptible highs and lows..."
On Monet's Rouen Cathedral paintings, from Monet and Modernism, page 136.
If you think all Monet did was down to talent rather than technique, I hope this quote will help persuade you otherwise. His dancing, shimmering colors were created with technique, not magic.
