  Here I am discussing a possible use of a Roman Dodecahedron, a bronze
artifact of gallo-roman origin, for measuring distance. A dodecahedron, found
at Jublains, the ancient Nouiodunum, dating from the 2nd or 3rd century AD, is
used to create a model. Looking through the model, it is possible to test it
for measurements of distance based on similar triangles.
