Trundholm Sun Chariot Disk: Evidence for a 360-Day Bronze Age Calendar — E8 Intelligence Research

FINDING: The search results are largely tangential — the core hits are YouTube videos on eclipse prediction and an arxiv paper on the Yamabe flow (a PDE, not ancient math). The only directly relevant item is the Trundholm Sun Chariot disk analysis, which proposes a 360-day calendar from bronze disk decorations. No explicit base-60 divisibility or 120° symmetry evidence is present in the supplied abstracts. MATH: From the Trundholm paper (arxiv 1203.2512): proposed calendar = 360 days. This implies 360 = 2³ × 3² × 5, divisible by 3 (360/3 = 120) and by 6, 12, 60. The 120° rotational symmetry is implicit in 360/3 = 120, but no explicit geometric diagram or ratio is given in the abstract. No constants 0.382, 0.618, 0.786, 1.618, 2.618 appear. The Yamabe flow paper (1606.02914) is pure modern PDE — irrelevant to ancient mathematics. CONNECTION: The 360-day calendar directly links to base-60 (360 = 6 × 60). The divisibility by 3 yields 120° — the rotation angle of a trigonal (3-fold) Author: Andrew Stewart Caldin, Independent Researcher, UK. Part of the E8 Intelligence Research series.
