I Had always wondered about the curious T shape and what it might be for.
My evaluating bias on megalithic work is towards the more functional purpose rather than the symbolic, because I have an enormous respect for how work of that scale of challenge can quickly clarify ones commitment to its completion. In other words, I presume you have to have a very good reason to do it. Anyone can make a grandiose plan to erect massive stone works, but a few weeks of discovery how frail a human is in comparison that that enormous weight and a few slipped discs, and you have to have a great reason to finish it, or you'll quickly become the biggest advocate of not bothering if your initial reason for it doesn't ease your pains.
So with that approach to Gobekli Tepi, I see their arrangement in those circles and initially I presume they might be holding up some roof structure. But listening to Robert Schoch, he points to several examples that show how some of these stones appear to have been reassembled by propping them up in place, using sometimes broken pieces of other pillars under the bases to support them. There are several that appear to be broken in half and are propped up on smaller stones to raise them to the level of the others and have side supports of loose stone walls sandwiching them on either side to support them. To him, it appeared to reassemble some earlier structure that might have crumbled or succumbed to a cataclysm.
I found that curious to think about, because that opened up the idea that their original configuration might possibly be somewhat different. Its still such a big mystery. But by virtue of that simple idea that these pillars may not have been erected in this final configuration opened up my mind to the possibilities of what they were for. And immediately I could discard the roof structure idea for starters.
And then I considered that odd under cut that defines the overhand of the "T". I couldn't think what that might be for in any construction terms that would necessitate the huge challenge of carving that extra weight to make them so top heavy. It goes against any reasoning for a structural purpose to have that feature not repeated on the bottom at least. Very curious.
But then I thought maybe that upper "T" undercut shoulder might possible be to suspend those rocks from those points possibly if in fact the original purpose of those stones was to be suspended from those upper "T" shoulders, for some vibration function.
I thought about that curious ringing stone demonstration that Michael Tellinger has on many of his video's that shows the interesting bell sounds that come from some of those stones he finds in Africa. And I've also read countless post on here and in books about the existence of vibration and sonic tuning of stones for a mysterious purpose that some ancient civilization must have gained some functional value from that effect.
And with those thoughts, the shape of those stones being so top heavy with those wider T top shoulders sticking out just enough to provide suspension support if it were to be hung started to make sense. Also, Robert Schoch also discussed the fact that based on the weight of those stones, they should have been burried at least a third of their length in the ground for them to be for the purpose of standing pillars, and yet most of at least the center pillars seemed to have bases that only had a slight depression on them for the pilar to sit, which offered them zero stability were they to ever have been placed on those bases.
So its a new thought on their possible original configuration and purpose that I wanted to post and hear if anyone had any thoughts on that.
