What Survived, and What It Leaves Out

social-09-ancient-world asked at nine which things would still be here in three thousand years. This asks the harder half: the losses are not random. Stone lasts and wood does not, writing lasts and songs do not, and the rich were buried with things while everybody else was not — so the record does not merely have holes, it TILTS, and it tilts the same way every time. Which means you can work out which way, and correct for it.
