Centered dots for spaces
If you download the diigo toolbar to your browser, you can highlight text and add notes. If you see highlighted text in my links, roll over it to see my note with it. -Dave
The earliest writing had no capitalization, no spaces, and a few punctuation marks. This worked as long as the subject matter was restricted to a limited range of topics (for example, writing was initially used for recording business transactions). Expanding the use of writing to more abstract concepts required some way to disambiguate meanings. Until the 18th century, punctuation was principally an aid to reading aloud; after that time its development was as a mechanism for ensuring that the text made sense when read silently.[1]
The oldest known document that uses punctuation is the Mesha Stele (9th century BC). This employs points between the words and horizontal strokes between the sense section as punctuation.
