The Olmecs used chocolate for religious purposes.
Common Olmecs likely produced only useful"art" such as pottery vessels.
We know the Olmecs primarily through their art, sculpture, and architecture.
Most common Olmecs were simple farmers
and fishermen who lived in family groups or small villages.
The Olmecs controlled central Mexico and Guatemala,
and the pre-Incan Chavín people managed large areas of northern Peru.
Because the Olmecs preferred to live in or near flood plains,
they built their homes on small mounds or platforms.
The Olmecs preferred to make settlements near water,
as the floodplains were good for agriculture and fish and shellfish could be had more easily.
Along with the sculptures,
altars and tombs are a series of giant basalt heads for which the Olmecs- the mother culture of Mesoamerica- are famous.
It has only recently been
discovered that Mesoamerican peoples(which includes Aztecs, Olmecs, and Mayans) were making rubber(though they didn't call it this)
three thousand years ago.
Not only are the Olmecs a pristine civilization,
they were the only ones to develop in a humid forest environment, making them a special case indeed.
These cities, which have been extensively investigated by archaeologists, were indeed impressive centers for politics, religion, and culture,
but most ordinary Olmecs did not live in them.
The first great Mesoamerican
culture, it had been in decline for centuries before the arrival of the first Europeans, therefore, much information about the Olmecs has been lost.
There is much that is still unknown about the Olmecs, including some very important,
basic things such as what they called themselves("Olmec" is an Aztec word applied to sixteenth-century dwellers in the region).
Common Olmecs who worked the fields and caught fish in the rivers
probably only participated in religious practices as observers, because there was an active priest class and the rulers and ruling family most likely had specific and important religious duties.
On the other side of the pond a calendar had been devised, not unlike the one the Romans had come up with,
by a culture in Central America called the Olmecs, and was fined tuned around the first century AD by the Mayans.
