# UNESCO Samos listing includes the Tunnel of Eupalinos, later attached to the island’s fame not as his autograph

Date: 1992

## The fact

The 1992 UNESCO Pythagoreion listing includes a water-tunnel of the archaic island. Later tourist copy can attach it to [Pythagoras](/people/pythagoras) without an autograph.

## Context

Split the listing as conservation-access. This stores mis-attribution risk as a knowledge-and-energy heading confusion.

Pythagoras is not the sole author of every later object, law, or museum label that uses the name. Shared work with courts, excavators, printers, spouses, officials, and later states does not erase a documented role, and it does not make an ancient person the signer of a twentieth-century statute.

## Evidence and sources

Official encyclopedia, Loeb, or heritage pages and an independent publisher independently describe this instrument.

Official or archival record: UNESCO — Pythagoreion and Heraion of Samos (https://whc.unesco.org/en/list/595/; UNESCO World Heritage Centre).

## Significance

A 1992 listing is not a 6th-century engineering diary of Pythagoras.

A 1992 listing is not a 6th-century engineering diary of Pythagoras.

## What is established and what is not

Established as a dated public record of this instrument.

What would change the picture: a contradictory original with a different date or name, or a measured series that can be argued, with lag and alternatives, as a consequence of this instrument rather than of later institutions.

The date is the date of this instrument, not a licence to back-date every later harm or benefit.
