Evidence and method
Methodology
How the five conversion matrices work; how uncertainty is propagated; why standards stay separated by dimension, region, period, and provenance.

About Ancient Measures
A source-led research utility for ancient units, monument geometry, and the history of numerical interpretation.
Academic in method; careful in claim.
Every converter record is attached to a source, period, region, basis, confidence level, and uncertainty where the evidence permits. Measured dimensions and reconstructed standards are kept separate from theories about symbolism or intention. The site is designed to be checked, questioned, and corrected.
What this project does
Ancient Measures makes historical measurement systems usable without pretending that an ancient unit had one universal value. It combines five dimensionally separate converters with a catalogue of unit dossiers, monument studies, geometry tools, and journal essays. The calculator states what the evidence supports; the essays investigate what the numbers might mean, with interpretation clearly marked.
It is edited and published by Joe Foley in Brisbane, Australia. The project is built as a static, reproducible research aid for researchers, writers, students, educators, and curious readers.

Primary trail
Source register
The public provenance layer for 189 standards, geometry formulas, artefact claims, and monument context, drawing on scholarship, museums, heritage bodies, and government references.
Editorial discipline
Editorial standards
The fact-versus-interpretation boundary, source hierarchy, correction practice, and disclosure of AI assistance in research organisation, drafting, code, and quality checks.
Field guide
Units catalogue
Browse all 189 linked standards across Length, Weight, Time, Liquid, and Area; each record keeps its historical context beside the conversion value.
Public research
Temples and sites
Ten ranked monument studies, beginning with Giza as the methodological exemplar, and placing measured dimensions before geometric readings.
Journal and tools
Essays and calculators
Read the journal for historical arguments and source criticism; use the pyramid, dodecahedron, Giza, converter, and Treasure tools for transparent numerical exploration.

A compact research boundary
The catalogue is a defensible core, not a claim to contain every ancient unit. Local standards, commodity-specific systems, chronological reforms, variable seasonal hours, and disputed calendar correlations are excluded or labelled until a specific corpus and chronology can be named. A close numerical pattern may be interesting; it is not, by itself, evidence of ancient intention.
