The Matthew Cooke Manuscript (British Museum: “Additional M.S. 23,198″) was written c1450. A transcript of a yet older document, it was written by a Speculative Mason.
This version is a faithful transcription taken from G. W. Speth’s Commentary appended to the Lodge Quatuor Coronati facsimile in Vol. II of its Antigrapha, published in 1890.
