Enuma Anu Enlil as a Sexagesimal-Indexed Decision Tree Rule Base — E8 Intelligence Research

FINDING: The omen compendium *Enuma Anu Enlil* (EAE) is structured as a sexagesimal-indexed decision tree — a rule base keyed by base-60 tablet/line addressing, not merely a list of omens. MATH: - Indexing scheme: 70 tablets (EAE 1–70), each subdivided into numbered lines; the canonical address is a two-level tuple (tablet, line) — a base-60 positional index at the tablet level (60 + 10 = 70, i.e., one full sexagesimal cycle plus a decade). - Conditional structure: antecedent→consequent rules of form IF (celestial/atmospheric sign S at time T) THEN (outcome O). This is a production-rule system, i.e., a decision tree over a discrete state space. - Sign variables are drawn from observed periodic phenomena (lunar/solar/planetary/weather), which are themselves sexagesimally quantified (e.g., 30-day months, 360-day schematic year, 12:1 and 60:1 unit ratios). - The 70-tablet count decomposes as 60 + 10; the 10 is the "decad" completing the cycle — consistent with base-60 place-value closur Author: Andrew Stewart Caldin, Independent Researcher, UK.
