A Forensic Investigative Brief and Multi-Variable Diagnostic Framework Regarding the Northwestern Provincial Roman Dodecahedra
For over two centuries, classical archaeology has addressed the hollow, cast-bronze Roman dodecahedron (over 120 standardized specimens recovered across Roman Gaul, Germania, and Britannia) primarily through fragmented, single-variable hypotheses. This paper presents an integrated, 56-pillar abductive diagnostic framework and multi-physics benchmark accounting for thirteen concurrent physical, metallurgical, aeroacoustic, kinematic, and contextual anomalies. We model the artifact operating within concave and oblong lathe-turned wooden vessels (scaphae and coni) deployed in architectural window embrasures (solaria). Under incident atmospheric wind, the system functions as a coupled aeroacoustic resonator (generating edge-tones, multi-port Helmholtz cavity resonance, vena contracta hole-tones, and thin-plate modal vibrations) and an autonomous polyhedral kinetic engine. We demonstrate via the Work-Energy Theorem that while static initiation from an eccentric, casting-jitter-induced 3-point tripod stance (vcontact=0) requires a transient gust (65.8km/h, or 43.9--54.8km/h ambient wind under masonry Venturi amplification), sustained dynamic rolling requires only 0.13N of aerodynamic drag (21.8km/h, an 89% reduction). Rolling across a tunable particulate-viscoelastic composite bed (Scomp: refined beeswax doped with high-albedo - white quartz silica sand, φ_sand = 5% to >50%, ≤ 150 µm), the 20 spherical corner nodules undergo three-body hydrodynamic micro-lapping while deterministically inscribing self-inverting three-strand braided ribbons (guilloche plaitwork) and closed orbital rosettes. These unmediated, wind-driven inscriptions (signa oblativa / non manu factum / acheiropoieton) served both as direct refractory lost-wax (cire perdue) foundry patterns and as the sacred geometric templates later absorbed into Romano-Celtic and early Christian monumental art. Full falsification protocols (CFD, laser Doppler vibrometry, confocal tribometry, and Schlieren thermography) and an open-source Python numerical kinematic simulation are provided.
