| Script | Who | Where | Deciphered? |
|---|---|---|---|
| Harappan / Sindhu lipi | Harappans | Indian subcontinent | No |
| Cuneiform | Sumerians | Mesopotamia | Yes |
| Hieroglyphic | Egyptians | Egypt | Yes |
- All three flourished around the same time.
- The deciphered ones mark the beginning of the historical period, about 5000 years ago .
- This is why we know far more about Mesopotamia and Egypt than about the Harappans.
