Deciphering Secrets turns medieval Spanish records into a public research desk. Volunteers can learn the historical context, examine manuscripts, and contribute classifications or transcriptions that help scholars study everyday ties among Jewish, Christian, Muslim, and convert communities.

What is Deciphering Secrets: Unlocking the Manuscripts of Medieval Spain?

The documents here are not royal pageant alone. The project is especially interested in transactional material such as leases, sales, agreements, and taxes—the paperwork through which neighbors, institutions, and faith communities encountered one another. Its wider collection brings together thousands of folios and transcriptions connected to Burgos, Toledo, Plasencia, and Granada. Zooniverse supplies the public-facing workbench, while the About pages provide enough history and paleography context to explain why a cramped line of handwriting can matter.

What you can do there

  • Learn the historical and archival context
  • Classify and transcribe medieval manuscript material
  • Discuss subjects with the research team and volunteers

Why we picked it

This is a rare chance to meet history before it has been flattened into a finished paragraph. The project connects small acts of careful reading with a larger question about coexistence and conflict, and it shows how digital archives can be built by scholars and curious volunteers working from the same stubborn ink.

How to get the most from it

Read the Research and Education pages before opening Classify, especially if paleography is new to you. Follow the project tutorial closely, zoom in on letter shapes and abbreviations, and use Talk when a document raises a genuine question rather than forcing a confident guess.

Good to know

The work rewards patience more than speed, and some handwriting or historical terminology may be difficult. The active workflow and account requirements were not verified in this pass. Project materials are described as CC BY-NC-ND 4.0 unless otherwise noted, with manuscript images stated to be public domain or used by permission.

Who made it, and when?
