In this episode, Ulisse will make an exciting journey among the very first civilizations that appeared in Central America, long before the arrival of Columbus, the Olmecs, the Maya, the Aztecs. The famous heads carved in rock have come down to us from the Olmec people and what amazes and still remains an unsolved mystery is how the Olmecs managed to create these amazing sculptures and, above all, to transport the colossal blocks of rock that they used; we will follow the experiment of an English team that attempted to transport a boulder weighing between 10 and 20 tons and create, using only archaic techniques, a copy of a gigantic head.
