Archaeometry is the application of scientific techniques used to analyze archaeological materials. The Cretan Bronze Age Minoan Kernos, has hitherto, been regarded as a gaming board or for religious purposes. Here, it is shown, that, it was designed, specifically, to predict the occurrence of the 9th. January 1860 BCE Total Solar Eclipse. A prototype magnetic compass was centrally facilitated in a non-magnetic marble structure, whose geomagnetic declination angle, appears to coincide with the Kernos’ eclipse prediction-axis orientation. Comparisons of eclipse constructions taken from Kernos measurements, with those of Hipparchus (2nd. c. BCE), appear to be similar, suggesting a common origin. Evidence obtained using a multidisciplinary approach, is testament to the sophistication of Middle Bronze Age science and technology and the ability to create a mathematically-based eclipse predictor and magnetic compass, 3800 years ago and 1700 years before the advent of the Antikythera Mechanism.
