マヤ文字
The Maya writing system is one of the outstanding achievements of the pre-Columbian inhabitants of the Americas. It was the most sophisticated and highly developed writing system of more than a dozen systems that developed in Mesoamerica. The earliest inscriptions in an identifiably Maya script date back to 300–200 BC, in the Petén Basin. However, this is preceded by several other Mesoamerican writing systems, such as the Epi-Olmec and Zapotec scripts. Early Maya script had appeared on the Pacific coast of Guatemala by the late 1st century AD, or early 2nd century. Similarities between the Isthmian script and Early Maya script of the Pacific coast suggest that the two systems developed in tandem. By about AD 250, the Maya script had become a more formalised and consistent writing system.
