I reproduced the diagram in the book, expanded its size, transferred the pattern to a better sheet of paper, colored it, glued it down on good craft paper, and I even had it laminated at a nearby office supplies store and bought a wooden tray to keep it in. I still use it occasionally and find it helpful. Reproducing the diagram of Herne’s Head here would put me in danger of copyright infringement with the author. But my creative juices started flowing. A divinatory picture, what a great idea! A basic design of spiritual significance, with a number of symbols added to it. Each element of the picture would have to be capable of having a light and shadow-meaning attached to it. If I were going to do my own variation of a divinatory picture, how would I do it? Hmmm…
My religious orientation is Druid, so I decided to go with a tree as my basic design. The symbols are culled from both the Internet and Microsoft Publisher’s own shapes. A few symbols on my picture also appear on Herne’s Head, but most don’t. I approach my divination-diagram set of meanings from a problem/solution standpoint. The ‘shadow’ stone indicates what the fundamental problem is. The ‘light’ stone hints at where the solution lies.
You can leave the tree pictogram plain, like I show in the photograph above, but I think coloring it is a nice way of imbuing it with your own energies and making it yours. Use it only in a tray or a box lid, because you don’t want your light and dark stones sliding off or bouncing off the picture. If you don’t have a tray or a box lid, a shallow baking pan with straight sides will suffice. With both stones in your hands, ask for the aid and guidance of God(s), ancestors, angels, spirit guides, Higher Self, Whomever you invoke to speak to you when you’re divining. There’s one line from Callia Underhill’s ritual incantation I like to incorporate into my invocation when I consult either her divination picture or mine. Show me the problem’s source and the future’s course, because that line pretty-much sums up what you’re seeking with this divination tool: what’s my fundamental problem here, and where does the solution lie?

I have and love this book… I did my own house of goddess box from that book!!! Thank you for sharing your post-!!
You’re welcome! Callia Underhill is quite a talented and creative diviner. Her book still spurs my own creativity in the area of divination.
