GoKawiilResearcher uses Claude Opus 5.5 to surface unnoticed 1615 Dutch dodo-hunting account
A historical researcher describes using Opus 5.5 alongside semantic search over the GLOBALISE archive of Dutch East India Company records to locate what appears to be a previously unidentified 1615 Dutch report describing dodo hunting. The method combined prior specialist knowledge of the exotic animal trade with embedding-based search to surface candidate passages, which the model then read and ranked for human review. The account follows a similar case where a researcher used GPT-6 Astra to break a long-unsolved Napoleonic-era cipher.
