  Geometry is essentially a global language, which is fully understood in
different times, countries and cultures. The proof of a geometric theorem (e.g.
the Pythagorean Theorem) or a geometric construction (e.g. the construction of
an equilateral triangle with straightedge and compass) is recognized in more or
less the same way by everyone. This fact, in combination with other parameters,
brings out a human face for geometric and mathematical achievements in general,
thus allowing people and civilizations to come together.
