The fish in your hand belongs to a tradition far older than the can it sits in. This tool returns the distance.
The first known printed use of “sardine” in English is dated 1382. Roman fish-salting along the Iberian Atlantic ran from roughly 200 BCE through 400 CE. Industrial canning was invented at Massy in 1810. The first sardine cannery opened in Nantes in 1824. The last American sardine cannery closed in Maine in 2010. The Preservation Timeline is the operational companion to Field Note IV · The Fish That Solved Distance. Type a brand or pick a country. The tool returns the four origins, the preservation system attached to your packing medium, the labour history behind the country’s cannery floor, and the current stock status of the species. Every record carries an explicit evidence-confidence level.

Canned sardines do not sit at the start of a tradition. They sit roughly 1,800 years after Roman cetariae were already salting fish at industrial scale on the Iberian Atlantic, and roughly 540 years after the English language attested the word “sardine” in print. The 1810 invention of canning at Massy and the 1824 opening of the first dedicated sardine cannery at Nantes were technological hinges, not origins.
Every reading on this timeline carries an evidence-confidence level, namely Strong for primary historical sources and dated artefacts, Moderate for industry-history references and corporate heritage, Preliminary for unaudited or contested attributions. The cross-cutting Global Sardine Standard Map is the reference atlas every record here sits inside.

Where this Timeline fits in the audit
The Borlaug Scholar Field Notes series reads every can in five layers. Each layer has its own operational tool, plus a cross-cutting reference atlas that all five consult.
- Front of pack · the feeling. What words is the can selling? Health Premium Decoder
- Back of pack · the math. Sodium, protein, price, packing medium. Health-Washing Decoder
- Country of regulation · the rules. Codex, EU, FDA, national label law. Global Sardine Standard Map · the reference atlas of the series
- Equity register · the owner. Who profits when you buy this can? Brand Owner Decoder
- Preservation history · the centuries. What tradition does the fish belong to, and how old is the can it sits in? The Preservation Timeline · this tool
