For much of the twentieth century, Harry Carr's Transitional Theory became one of the most influential explanations for the origins of speculative Freemasonry.

But what does the historical evidence actually tell us?

In this episode of Masonic Muscle, we investigate the Transitional Theory using the same historical framework established in Campaign Two: The Great Investigation.

Rather than asking which theory we prefer, we ask better questions:

• What is the claim?
• What evidence supports it?
• What evidence raises additional questions?
• What can the surviving documents actually tell us?

We'll examine the Schaw Statutes, the earliest Scottish lodge records, accepted Masons such as Sir Robert Moray and Elias Ashmole, and the Edinburgh Register House Manuscript to better understand why Harry Carr's explanation became so influential among modern Masonic historians.

Whether you're a Freemason, a student of history, or simply fascinated by how institutions evolve over time, you're invited to join the investigation.
