I've often wondered about the significance of the obelisk but have always been at a loss. Obviously, due to its shear size and the fact Ed took the trouble to move it from Ed's place it is more than an ornament. Instead of boring you with my previous theories, something dawned on me when I was studying Ones65118's map of Ed's place...could it be a way to put Venus (or another star) in position as related to the moon on the wall?
I'd be interested to know, assuming that the star on the obelisk represents a star or planet, if there was ever a planetary alignment that coincides with the planets on Ed's wall. Perhaps an alignment that repeats through time. I've been searching but have come up short. I did however run into a theory called a T Square (I think) planetary alignment that apparently happened in the 30's (a theoretical blame for the Great Depression and the collapse of Rome).
Some people have seen the Holy Oak King is some of Eds pictures, overlays forming an old man face or head.
The five pointed star represents the five elements, the shape of the obelisk is extremely important
The obelisk can also relate to the star of Ra, or the blazing star. I believe it relates to the star and crescent. Will post more later.
I tried to attach two sections of the same picture in order to provide a sharper image, I think it is important to try and see the other stars
