The Sphere of Pythagoras

Editorial interest 88/100 Selection signal · not a rating of the site

A bilingual interactive reconstruction of a medieval name oracle, using a name, weekday, and lunar age to produce a prognostic result.

Landing page captured for the 2026-09-13 issue.

Field notes

The page models one specific transmission of the Sphere of Life and Death rather than claiming to reproduce a standard medieval algorithm. Users provide a name, weekday, and lunar day; the interface then exposes the arithmetic through a 17-step demonstration and places the remainder in PARVA, MEDIA, or MAGNA columns for approximate timing. Its notes distinguish historical material from modern additions, including the treatment of W as two Vs and the handling of exact multiples of 30 as AMBIGUA.
