Some where I read the following. Left to right due to cultures which first wrote on clay or paper with a stylus or pen-like device. A right handed person would not smear previously written data. Right to left due to cultures which first wrote with a hammer & chisel on stone. Hammer in dominant right hand Vertical due to cultures (example Chinese) which first wrote with a paint brush
Interesting. I am going to go into work tomorrow with a hammer and chisel. And if anyone cries foul, I'll scream oppression! to HR.
A fair number of hammer and chisel folks "wrapped" the lines - so they alternated R->L, L->R, with the "letters" themselves mirrored. https://en.wikipedia.org/wiki/Boustrophedon
......which practice sometimes got carried over into other media, such as stained glass representations of sequential scenes, e.g. in La Sainte Chappelle in Paris (which where I first encountered this splendid word Please Register or Log in to view the hidden image!).
If something is moving to the starboard side it means the viewer is moving leftward. Down means you are rising. However I am of the belief the Western writing system moves towards the individual.
Or not moving but yawing clockwise. Or you are not moving but pitching backward. So, getting larger...
When facing forward on a ship, starboard is right & port is left. These terms are used to avoid ambiguity by referring to the ship rather then the human speaking. Similarly: Fore & aft refer to the prow direction & the stern direction.
what cultural association has impirical symbology of movement that supports the motion direction to assert social normity ?
From Rainbow Post 13 I think (& surely implied) in my Post that the cultural direction of writing was due to the method of writing. BTW: Why not use a spell checker or learn how to spell? I apologize for this remark if English is not your native language.
Do tools define culture ? Does tool use define culture ? Does culture define tool use ? Does culture define communication ? Do humans share a common anthropological process of Kinesiology which expresses its self through a common function of communication variables in spite of culture ? When you remove that from the end result (reverse engineering the function & tools) do you get left with a common denominator that 'may be' a driving force of the process of writing ?
Side point: unless presented with excellent and very persuasive evidence, I am not going to believe anyone anywhere "first" wrote with a hammer and chisel in stone. That just strikes me as - - improbable.
That's how I remember it Gawdzilla! On a plane the port light is red. Because it's the same colour as port. ☺
And "red on the right, returning", meaning the masthead lights indicate that the ship is coming at you.
