The Appleby Institution

The Appleby Measure

A unit of length that produces whole-number counts at sites of ancient significance worldwide.

The Appleby Measure is a unit of length first documented by the Institution in 1706, though the founding surveyors noted it as a rediscovery rather than an invention. Its value is approximately 0.832 metres, though the Institution uses a more precise figure not published in open documentation.

The significance of the Appleby Measure is that it produces whole number counts at sites of recognised ancient significance worldwide, in cases where standard metric and imperial measurements produce irrational results.

Verified Correspondences

The following correspondences have been verified by the Institution’s survey teams and are available for public review in the Archive:

  • Long Meg outlier to circle centre: 1,706 units (verified 1894, W. Rawlinson)
  • The Avenue at Avebury, full length: 2,448 units (verified 1923)
  • Gobekli Tepe Enclosure D, primary axis: 108 units (verified 2011)
  • The Great Pyramid base perimeter: 3,600 units (verified 1897, W. Rawlinson, documented separately from Long Meg survey)

The Institution does not claim these correspondences constitute proof of any particular theory of ancient civilisation. The Institution notes that they exist. The Institution leaves interpretation to the reader.

Giza, 1897

In December 1897, following his return visit to Long Meg, W. Rawlinson travelled to Egypt. He spent eleven days at Giza. His survey notes from this visit have not been released. His covering letter to the Institution, submitted on his return, contains the sentence: The measure was known here. The covering letter is available from the Second Degree. The survey notes are withheld indefinitely at the Warden’s discretion.
