I bookmarked this site Art Renewal Center (ARC) a while back. I like to revisit it every now and then to view the inspirational works of art. Although I primarily work in Mixed-Media, I get energized by fine art.
One of ARC's goals is "to create the largest on-line Museum on the Internet, with hundreds of thousands of over-sized high quality images of all the known works of the greatest painters and sculptors in human history......" You can read more about their Mission on their site - and view some of your favorite paintings.
I have always liked "The White Girl" (see below) painted by James Abbott McNeil Whistler. (Whew - I never realized what a long name he had.)
Have a creative day, Darlene
