It is common to find identical ideograms in different
parts of the world that, according to today's prevailing theories,
have had no earlier connections with one another. Such is the case
with this sign, found both in pre-Columbian Central America (in Aztec
symbols representing the world), on sword-hilts from the Bronze Age in
the Nordic countries, and on the Phaistos disco. This is a small disc made
of burned clay, about 15 centimeters in diameter, with an ideographic
script running in a spiral. There are about 120 signs in some 30
groups on each side. It was found at the excavations of a prehistoric
town on Crete. It is approximately 4,000 years old.
