Ancient Celtic Crosses can be found in many parts of the world. But nowhere can you find them like you can in the countries of Ireland, and Scotland.
These symbols are a combination of a cross with a ring surrounding the intersection. One of the world's foremost experts on the Celtic Crosses, Crichton E.M. Miller says they were used to tell time with the heavenly stars above, and also measurement.
Essentially, they were ancient mathematical timepieces and scientific instruments.
