Survey before symbol
Petrie’s work provides measured dimensions and explicit discussion of cubit values. That evidence allows later readers to test both conventional architectural models and extravagant pyramidology.
A cubit from several clues
Different parts of the Great Pyramid yield slightly different estimates. A weighted representative near 20.62 inches is powerful precisely because the variation is visible; it is not a magic number announced without method.
Read critically and productively
Methods and interpretations age, but a transparent survey remains reusable. The site links the digitised book, distinguishes Petrie’s data from later claims, and invites users to inspect how a chosen base and height generate ratios.
