The Maya civilization was a Mesoamerican civilization developed by the Maya peoples, noted for the Maya hieroglyphic script, the only known fully developed writing system of the pre-Columbian Americas, as well as for its art, architecture, and mathematical and astronomical systems.he Maya civilization developed highly sophisticated artforms, and the Maya created art using both perishable and non-perishable materials, including wood, jade, obsidian, ceramics, sculpted stone monuments, stucco, and finely painted murals.
However, this early society was followed by the Mayans in the same regions of Mesoamerica.  Early Mayans developed a farming society that adapted to their environment in the rain forests of Guatemala. The planting consisted of their most important crop, maize or corn.
