This diagram is a reminder to myself that how a manual interference can be done and affects what . It breaks up in to 2 (before Guthenberg).
First one is thin - thick relationships which is changing according to the tools used to write.
Second one is the monolinear structure - the structure of typefaces when their vertical and horizontal stroke weights considered visually equal. This point us to the script family the typeface belongs to.
The diagram will expand as more is done.
