I'm also a bit interested in history...
....it's the most archaic and natural way of shooting
A pinch draw is probably more archaic and 'natural'. Mostly what Paleolithic people would have done.
and includes a lot of mind related stuff.
Some of it more than others. Some people add more mind stuff then is really needed and others vice versa.
Olympic archery seems very far from what bows and arrows were used for the last 20000 years in hunting and war....
This much is true. Except the war thing. That probably doesn't happen until the Neolithic or later Meso.
And while this Saracene Archers stuff is very interesting, this is propably only a very small part of the knowledge that existed to survive as a human race for 10 thousends of years.
So Saracen Archery is actually based off of a treatsie on archery written by Taybugha in the Middle East in the 1300s. I find myself repeating things alot in this conversation.... Anyway, his work was not entitled 'Saracen Archery' mind you and there were plenty of other treatsie on archery not only in the middle east, but also Europe, and East Asia. The thing with Saracen Archery is this: it is the most accessible, most comprehensive translation with insertions on Asiatic archery we have today. There is a lot of stuff probably from Joseon era Korea but also feudal Japan that we don't have access to because it has not been translated yet for western consumption.
I also believe that Koreans speak Korean but not Arab,...
Good belief to have as its is actually backed by empirical knowledge too.
so the word Khatra might have been unknown there for thousends of years.
Not only the word, but technique too. I mean, make sure you understand what khatra is and what it actually refers to. Then ask a Korean archer, if in the history of Korean traditional archery, if such a technique has ever been utilized.
Also ask them what they refer to their torque technique as. You will likely get two different terms out of them and explanations if any for the first.
Keep in mind though, some techniques may be newer then you think and clearly not as ancient.
Our knowledge is very very small, maybe during some times most people were able to shoot like Lars Anderson, just cause they had to in order to survive.. who knows?
Actually what Lars does is straight out of the exhibition style shooting section of the book entitled 'Arab Archery' which is yet another treatsie on archery written in the middle east. Its unlikely that what he demonstrates was used by the average archer or even all that practical especially when factoring draw weights of bows used in combat at that time. Horn composite bows for war had draw weights ranging from 90 to about 150 pounds. Even the strongest of archers probably were not concerning themselves with all that trick shooting that Lars shows us and wants us to believe was used in a far more ubiquitous manner.
I mean, all those techniques are straight out of the 'trick' or 'exhibition' section of 'Arab Archery'. Says it clearly in the book. Our problem in more ways is not that our knowledge is very very small, but rather, given what we have learned or have access to is, more often than not, bluntly understood.
Many particularly on FB, YT, and elsewhere have a tendency to assign more to what is actually being presented and thus distort what the original sources have said leaving us with a poor(er) foundation then what we could have ever started with in the first place.
