I'd be interested to see any evidence this person has for his claims. After all, many people have been looking into the history of this cross for many centuries, and no evidence for its original form has ever been found.
Mind you, we have it on good authority here that it was originally a pyramid, and Kieren's brother should know, shouldn't he, cos he's "a Druid who is VERY well known and has published works".
Something is not right. This message is just to keep things from messing up down the road
