Cipher or unknown language - historical perspective

[Stefan Wirtz_2]

You all seem to count direction-changes and stops as different strokes.
I define "stroke" as a stop-offsetting-onsetting-start, like adding the  -  at "t" of "f".

The last series of close-up images shows more jumps, scratches and maybe lost ink particles on the pages' material, but these are exceptions and I would see all
8, 9, a, k, b, f, t, s, r, l etc. as natural one-strokers, designed for just that reason.
