In this post I was discussing whether the same painter did the following covers.
I finally got it figured out. As you can see from the second picture, the artist of Seer of Sevenwaters is John William Waterhouse. Since I had one name, I did a Google search (I love Google) (no excuse me, it was Bing!) and my quest took my to Amazon.com. I looked inside The Red Tent (I also love Amazon.com) and discovered that Nancy Resnick painted its cover.
Mystery solved. And Catherine was correct, it is two different artists.
