Predictive Archaeology and the Reconstruction of Hidden History in the Bosnian Valley of the Pyramids

Abstract

This article introduces a predictive archaeology framework developed through a cumulative series of geometric and statistical investigations in the Bosnian Valley of the Pyramids near Visoko, Bosnia and Herzegovina. Eight previously published studies have established, in sequence, that the valley exhibits non-random spatial structure: Fibonacci-based spiral geometry, straight-line alignments, near-equilateral triangular configurations, and cardinal orientations. Each layer of evidence was subjected to Monte Carlo null-model testing, with consistent results indicating that the observed configurations are statistically unlikely to arise by chance. Building on this validated geometric model, the present study applies a predictive methodology: If the known monuments of the valley—the Bosnian Pyramids of the Sun, Moon, Dragon, and Love; the Temple of Mother Earth; the Tumulus in Vratnica; and the Ravne underground tunnel network—are nodes within a planned spatial system, then the geometry of that system should predict the existence and approximate location of additional, as-yet-unconfirmed monumental features. A quantified inventory of 13 collinear alignments (maximum deviation ≤3%) and two near-equilateral triangular configurations is presented as the evidentiary base. Five candidate sites are evaluated: Dragon Head (43°59'06'' N, 18°11'57'' E), proposed as a sixth pyramid-form structure, and four tumulus-class monuments at Smreke, Bedem, Četnica, and Krtnica. For each candidate, positional correspondence with Fibonacci spiral trajectories, linear alignments, and cardinal geometric axes is assessed against the established coordinate framework. The results indicate that all five candidates occupy positions consistent with the predictive geometric framework, including the exceptionally precise Sun-Vratnica-Krtnica alignment (0.05% collinearity error) and the Sun-Dragon-Smreke near-equilateral triangle (97.72% equilateral similarity). These findings support the utility of geometric modeling as a prospective tool in archaeological investigation.
