End Marks Evolved From Performance Pauses
- Modern Western end punctuation (period, question mark, exclamation) evolved from performance-oriented pauses used by ancient scribes.
- Aristophanes' three-dot system mapped short, medium, and long pauses to comma, colon, and periodos, seeding today's end marks.

- He published it in TYPEtalks imagining advertising slogans like Who forgot to put gas in the car?
