So the Olmecs are considered the 1st great Mezoamerican civilization who lived from 1200 - 400 BCE. They're know as the "rubber people" because they were able to extract rubber from rubber trees. Some of the greatest things the Olmecs were known for were the huge, stone heads they carved and portraits of their rulers. They were interested in astronomy, not to be confused with astrology, as they would build their cities aligned with certain constellations. They did use glyphs, or hieroglyphics, on stones and dedicated monuments, pyramids, and tombs to their emperors and gods.
