The Olmec civilization was located in modern-day Mexico in between Veracruz and Tabasco along the Gulf Coast, also known as the Mesoamerica region. The Olmec civilization started in 1400 B.C. approximately, and the Olmec civilization is considered one of the earliest civilizations to create art in the Mexico region.
The Olmec created huge sculptures of their ruler's heads and primarily used stone, sand, water and chert to create them. The Olmec civilization also were the first people in the Mesoamerica region to develop a calendar, understand the idea of "zero" as a concept and create a writing system by using hieroglyphics. Later civilizations in the area such as the Aztec, Maya and Zapote would build off of these ideas.
