Although Thomas Dunckerley enjoyed some brief fame in the nineteenth century for the alleged brilliance of his Masonic writing, this perception was based largely on George Oliver's speculation about works which did not in fact exist. As for what Dunckerley did write, it is difficult to say what has been lost – certainly most of the thousands of letters he wrote over the course of his Masonic career are gone. Some few may be tucked away in forgotten corners, but it now seems unlikely that there is a cache of vital Dunckerley literature hidden in a Provincial Masonic archive, waiting to be discovered. Aside from correspondence, Dunckerley was an enthusiastic promoter of his own Masonic literature, and we can be reasonably sure that nearly all of what he was most proud of has survived. The most important examples of this are readily available: ‘The Light and Truth of Masonry Explained’ and his 1769 charge to the Freemasons in Marlborough are both included in Sadler's biography, which is available online and in facsimile edition. ‘The Moral Part of Masonry Explained’ was originally published as a companion to ‘The Light and Truth’, but had already fallen out of the public eye during Dunckerley's lifetime. Copies of this text are rare, but one may be consulted at the Library and Museum of Freemasonry at the United Grand Lodge of England.
