What the Old Builders Encoded in Stone So It Could Not Be Lost

They did not write it down. They built it, at a size that could not be edited.

True north from one upright rod, your latitude from a shadow, the day of the year from a star. What the old builders encoded in stone so it could not be lost — and the four tests that separate a real alignment from a coincidence.

Inside

• Why knowledge was put into stone — four properties of a record that cannot be quietly edited, and the design rule they give you
• The shadow rule — true north without a compass, your local noon, the turning of the year and your latitude, from one upright rod
• The alignments — what four separate cultures pointed their works at, why, and the four tests that separate a real alignment from a coincidence
• The clock overhead — reading the hour, the season and the day of the year from the turn of the sky
• The long count — four calendar solutions to one impossible problem, and the running count you should start today
• Reading a structure — six questions, in order, and the habit that separates investigation from confirmation
• The ledger — what the builders demonstrably had, what they did not, and why the honest account is the more impressive one
• The hours of the instrument, and the numbers of the builder — nine kinds of maker with the way each one's work collapses
• The four bodies of the watcher, including the rule that protects you from your own best findings
• The Nine Days — the rod, the sky, the count, and a sealed page opened a year later
