Flaming Sword Archive

The Flaming Sword was the weekly publication of the Koreshan Unity — a utopian community founded by Dr. Cyrus Teed in late 19th-century Florida. Over its decades-long run, the paper built a detailed case that Earth is a stationary hollow sphere containing the entire universe.

This archive indexes the articles that made that argument — verbatim transcriptions with scans and editorial notes. It's a work in progress: 785 issues survive, and only a portion have been transcribed so far.
