The 490d Unified Chronology
Forty years of systematic biblical chronology research, published as a structured, machine-verified source corpus.
What This Site Is
This research database documents biblical chronology across the three major manuscript traditions — Masoretic, Septuagint, and Samaritan — and tests them against further ancient witnesses, including the Book of Jubilees, the Sumerian King List, and Berossus. Alongside the tradition-by-tradition timelines, the corpus documents the numerical and structural patterns that emerge when those chronologies are compared: cumulative lifespan architecture, calendrical systems, prime-number lattices, and Christocentric time spans.
The research is the product of formal training and forty years of systematic analysis. Every claim in the corpus carries an explicit status label — textual datum, arithmetic fact, structural inference, typological reading, historical-critical inference, or theological claim — so readers can see exactly what kind of assertion is being made and on what basis. All arithmetic is machine-verified before publication.
How the Research Is Organized
The corpus is published as sixty public-clean source files — one topic per file, from the repository foundation (File 00) through the Creation Decade Protocol (File 56) — plus the control documents that govern vocabulary, procedures, and revision history. Each file is written in plain-text Markdown, served at a stable, version-free URL, and formatted so that human readers and AI systems alike can retrieve and analyze it directly. The WordPress pages you are reading are landing and discovery layers; the Markdown files are the canonical sources. They form the basis for planned academic publications.

Main Comparative Charts and Tables
Two foundational comparisons underpin much of the research — the Regular (begetting-age) chronology and the Cumulative (lifespan) chronology. If you read nothing else, read these:
