Nymue

Nymue is a druid from Arthurian legend. She is referenced as a sentient stained-glass-window in a fanfic I've been rereading lately. (The Changeling by Annerb)

I was inspired. 

In rare form, I reprinted this block in different colours because it was such a fan favourite. 

Fun fact:  This is the artwork that most people cited as the reason they knew I was queer before I did.
