In a study of three separate art types (stencilled handprints, linear geometrics and stones inscribed with “tally” marks) it is confirmed that the native aboriginal people of Australia described in a geometrical manner the data required to mathematically predict future eclipses. The method to encode the mathematical values involves the conversion of astronomical values to an angular array. The method is identical to the technique used in the upper Paleolithic era geometrics found in cave paintings at Lascaux, in France, and other ancient archaeological sites. In one sample of Australian artwork the encodement of astronomical data even appears to employ a three-dimensional geometrical trick to create a very basic optical illusion. Taken together the data suggests that it is now possible, for the first time, to scientifically compare dissimilar art types, and to use ancient art to investigate ancient migration paths.
