Vatican Secret Archives: What's Hidden in 53 Miles of Shelving

The Vatican Apostolic Archives contain 53 miles of shelving spanning 12 centuries. Access is severely restricted — only qualified scholars with specific research proposals are admitted, and even then only to requested documents.

Known contents include Galileo trial records, Henry VIII's annulment request, letters from Abraham Lincoln and Mary Queen of Scots, and papal bulls. But the vast majority remains uncataloged publicly.

Questions: What pre-Christian texts were absorbed when the Roman Empire converted? Are there records of early Christianity that contradict established canon? What suppressed scientific or historical documents exist? Why maintain such severe access restrictions if contents are purely administrative?

Initial probability: 60% that significant historical revisions would result from full access.
