At the end of April 2011, in a new section of Ravne underground prehistoric compound that was being cleared, an interesting piece of handwork was discovered by one of our close collaborators, a worker of the Bosnian Foundation of the Sun Pyramid.
From the earth filling up the tunnels a small, roundish sandtone rock emerged. It had two surfaces that had been polished and then carved by a human hand.
The stone’s dimensions were equal to 4x5 cm and its thickness around 3 cm.
Side A, as we will call it from now on, displayed a deeply carved triangle. Close to the triangle’s base there is a further angle with its bisector and in this point the carving seems less deep.
Fig.1 The side of the rock appears well polished on two sides
Fig.2 Side A of the carved stone. The triangle can be clearly seen
Fig.3 Side B bears several carvings with different depths and thicknesses
It was been erroneously exchanged for a very primitive six-pointed Star of David with a missing side, yet, depending on different interpretations it could be the solution to a geometric problem or a symbol related to the pyramid or simply a marking.
Apparently the carving has been carried out with a sharpened tool, with different pressure in order to mark the two geometric figures, the equilateral triangle and the angle with its bisector. However two different tools could also have been used.
Fig.4 The triangle shape on side A with height drawn close to the vertex and also the bisector of the angle above the base
Fig.5 The artifact seen from side B; carvings can be clearly seen
What we will call side B shows a set of carvings crossing each other to form different angles with different spans. Out of these lines, three seem to have been deliberately carved more deeply and with a different thickness compared to all other carvings.
Fig.6 Side B at the digital microscope. The different depth and thickness of carvings can be clearly seen
Fig.7 Deeper carvings on side B seem to form an angle close to the edge (digital microscope)
Fig.8 With tangent light, side B shows the depth of the carving (digital microscope)
Whatever the hypotheses on the possibile meanings of the artifact, the lines have not been placed randomly and microscope images with different lighting conditions seem to confirm the fact.
Whoever made it, had sharpened tools and therefore a suitable technology for the precision of the carvings.
Fig.9 The digital microscope highlights that on side A the height line drawn on the triangle puposely starts from the base of the triangle
Fig.10 The angles of the triangle drawn on side A appear clearly carved on the stone (digital microscope)
Such object has been found close to the trampling area and it appears almost impossibile to determine whether the artifact has been lost by chance inside the tunnel or if the object was part of the materials used to seal the tunnels and therefore abandoned during a certain historic period before the sealing of the galleries, as it was no longer being used.

In any case, further interesting abnormalities seemed to appear in the area of the finding. For the first time we could see a dry wall which is at right angles to the tunnel’s entrance, instead of sealing another tunnel. The structure seems to continue southwards, thus forming a slighly less than 90° angle. What could be interpreted as a small sidewalk runs parallel to the wall. The structure can hardly be acknowledged from an archaeologic point of view because it is made of the same material of the present trampling area. In this case, however the ground seems more compact.

Note after publication: in a more careful analysis of the B-side you can also see two triangles with opposing apexes at the center of the figure that also give a sense to geometric aspect of this side.
Many thanks to the Bosnian Foundation of the Sun Pyramid for the permission to publish pictures of the Ravne tunnels and of the artifact
