Why it matters
A planned city with covered drains and standardised bricks, and a whole literate civilization whose writing we still cannot read. We are missing an entire voice.
What mainstream says
Accepted major Bronze-Age city; the undeciphered script is an ordinary gap, not a mystery.
The memory of it
Mohenjo-daro is a planned Bronze-Age city of the Indus — gridded streets, covered drains, standardised fired bricks — built around 2500 BCE by a civilization spread across a region larger than Egypt and Mesopotamia combined. The unsettling part is not how it was built but how silent it is: its script has never been deciphered, so an entire literate people cannot speak to us. We grade the city as solid, accepted archaeology (grade A); the unread script is an ordinary scholarly gap, not proof of anything exotic. Its relevance is that a major, sophisticated civilization can become functionally unreadable — present in stone, absent in voice. If one of the largest early civilizations can fall this silent, the idea that an earlier one was lost more completely stops sounding far-fetched.
