"...On the internet, however, a strange object
turned up in 2009 on a website operated by a group of French metal detectorists.
In this year an anonymous hobby archaeologist found a metal object similar to
known dodecahedra at Saint Trivier de Courtes (Ain department).
But if we examine it closely, this object differs considerably from those we
call dodecahedra: it does not consist of pentagonal faces, but it is globular;
on which we find knobs arranged in circles: 6 above, 11 in the middle, and 6
below (23 altogether). Its holes are not circular either, but triangular and
pentagonal, and they are not arranged diagonally. At the bottom of the
sphere there is a flat base, with a hole in it."
