Some 5000 years BC, during the Neolithic period, the Hamangian civilization spreads along the Black Sea, where now Rumania stands. Besides the oldest written traces left in Europe, this civilization is attested by two small statues, both very sophisticated for their time.
One of them, the so-called Hamangian thinker, symbolizes the most typical human activity : rational thinking. It has been chosen as a symbol of Bayesia's working domain.
