I have found a photo of a Templar cross carved in the walls of the Temple of Karnak in Egypt. I will email it to anyone who can post it for me. The photo comes from the book, The Temples of Karnak by R.A. Schwaller de Lubicz. The photos were taken in the late 1940's and there is no mention of this in the text (of this book)as far as I know. It is interesting to note that the cross and circle are carved so that the image overlaps a stone joint instead of being placed within the face of a single stone. Why this was done, I dont know. Many of the egyptian carvings are done so that the joints cross at meaningful locations within a figure or text and I would assume that the Templars would have understood this and may have been attempting the same. It seems to have been done intentionally, rather than from lack of space. There seems to be other graffiti on the wall, but this carving is particularly well done and would have taken skill and a good bit of time to create. I will email a jpeg to anyone who will post it for me.
