This painting represents secret knowledge, as in alchemy or witchcraft, which is passed down or is learned by practice and study. The windows are barred, but light can still shine through. The door is covered with thick rivets and has no handle, but there is a window, even if dark at the moment--the implication that it can be opened to those who desire to enter. The walls are worn, but they are solid and thick and of a living color. It looks buttoned up, but there are ways to gain entry.
The original watercolor painting is 11 x 15"/28 x 38cm on heavy cotton watercolor paper and is ready to frame.
