The portal of the St. Marx cemetery (Friedhof St. Marx) shows a hexagram, well known as Star of David. Yet, I was told that this hexagram was (and still is) not meant as a Jewish symbol.
Interestingly, a number of gravestones there show six-pointed stars which some consider variations of hexagrams. Though, I found one engraving showing a six-pointed star within a hexagram.
What is part of a symbol?
One of Heinz von Foerster’s favorite symbols was the Ouroboros. (Von Foerster often used a variation where 2 snakes devour each other’s tail.)
At the St. Marx cemetery some gravestones carry Ouroboros, many with an arrow pointing from left to right.
Are symbols just symbols?
I vividly feel as if I was an Ouroboros on fire.
