Ancient Measures

Convert and calculate ancient units with academically sourced tools built from primary and scholarly evidence. Move from Classical epics to Tudor records and Roman artefacts across length, weight, time, liquid, area, and treasure; every result keeps its historical basis and limits visible.

A Style Fix Must Survive Regeneration

Semantic progress classes and a full-tree CSS check now keep generated pages within the shared style system; unchanged renders verify the extraction of legacy styles.

A Source Gate Must Name Its Source

Specific passage requirements now govern research readiness, so generic catalogue matches cannot release a blocked study or put it next in the queue.

An Analysis Page Must Answer to the Queue

A generated public report now ties every research commission, publication milestone and source holding to the same checked queue as the progress displays.

What Petrie Actually Gave Us at Giza

Reproduce Petrie's base-side mean and residuals, then see why a reconstructed dimension and an assumed ancient cubit count are different evidence.

Article programme

Every page, rebuilt from the evidence.

The site is rewriting its temple, unit and study pages one at a time. Each rebuilt page works from surveys and scholarly sources, and states its measurements with their limits.
