His other legacy — the grief of the people who buried him, the love expressed in 120 beads and an ivory tiara, the community’s insistence that his brief life deserved a specific and elaborate farewell — that legacy does not live in any scientific paper.

It lives in the objects held in Russian museums, in the careful documentation of the archaeologists who excavated the site, and in the recognition — which this account has tried to maintain throughout — that behind the genome and the AMS dates and the population genetic statistics, there was a real child, in a real community, who died young and was mourned.

Both legacies are real.

Both matter.
