Another essay by Norman Kleeblatt, from the same book says "Her structural reliance upon the grid and her gestural resistance to its constraints remains another oft-cited example of the contradictory aspects of Snyder's practice". Now, I'm the type that looks at the pictures then goes back and reads the text. This quote had me going back and looking at the paintings again.
It was interesting to look at these with the idea they started at some point with a grid.
The other book I own about Joan Snyder is titled Dancing With The Dark Joan Snyder Prints 1963 - 2010. by Faye Hirsch and Marilyn Symmes. In this book I learned that Snyder started out in college at Rutgers making wood cut prints, and continued making prints throughout her life.
One of my favorite pieces by her is Resurrection, 1977, which I don't have a picture of here, but includes oil, acrylic, fabric, wallpaper, newspaper and tissue paper, gold paint, paper mache, and graphite on canvas. Talk about collage!
I'll leave you with this "... to get from one place to another I had to do certain kinds of work which didn't always get my message out, but I was always struggling to get it across. Over the years, I built a visual language which now allows me to say anything I need to say."
