What is "archaeocryptography"

Archaeocryptography (from Greek , arkhaios, "ancient" and (kruptós), "hidden, secret"; and (graphein), "to write") is the study of decoding a monument or structure by determining the underlying mathematical order beneath the proportions, size, and placement to find any re-occurring or unusual data in respect to that which is being studied, or within another monument or structure.

Archaeocryptography is not a recognized branch of archeology or of any other academic discipline. It is an example of pseudoscience or pseudoarchaeology that employs contrived calculations involving many free parameters to achieve an impressive-looking result.
