I am sure I don’t understand it either….
but if I see something that with a slight modification reads :
O S S TN NSA CIA
wich is a reversal of the first 3 letters and the replacement of the letter O with an A and the letter S with a C.
A statue is erected, the O is pointed at in undergruund, the S is pointed at in palimpcest
Then I wonder is this just a coincidence, a dead end built in on purpose, or is there really something there that warrants further investigation?
