In the pre-Columbian era, Marajó island, at the mouth of the Amazon River, in Brazil was inhabited by a society named Marajoara. The pre-Columbian society may have ended, but the tradition on how to ornate artifacts still remains on the culture of the region, where natives continue to create artifact from pottery or other materials with the same type of patterns.
I own a few artifacts, from our current era that were brought to me by my brother, who often used to go on business travels to the North region of the country.
For more information about the Marajoara culture, check the Wikipedia article about it.
