I saw it in a print shop a long time ago, and I'd like to find a link to this picture. It's a woman in a white dress who looks like she is knighting a man who is kneeling and wearing armor (I think). She was holding a sword I believe, and I'm pretty sure she had long reddish hair. There are other people to the sides of the painting.
It definately looked like the style of Waterhouse, but sadly I couldn't find it on any related websites. It's a beautiful painting. If anyone knows this painting or one close to it, I'd be very grateful. Thank you!
