Script Usage in Petén During Preclassic Period

Evidence from the Petén region of northern Guatemala, particularly at the archaeological site of San Bartolo, shows that a developed Maya writing system was already in use by around 300 BCE. Discoveries made in the late 20th and early 21st centuries, including murals and inscribed fragments, provide some of the earliest known examples of Maya hieroglyphic writing. These findings come primarily from the Las Pinturas complex, where preserved wall paintings and associated artifacts have been dated through radiocarbon analysis and stratigraphy to the Late Preclassic period. The San Bartolo murals, uncovered beginning in 2001 by a team led by archaeologist William Saturno, depict mythological scenes alongside early glyphic elements. While the inscriptions are not as fully developed as those seen in later Classic-period cities, they demonstrate recognizable components of the Maya script system, including symbolic and phonetic elements. Additional finds in the region, such as painted pottery and carved objects, further support the presence of early literacy and scribal activity during this period. These discoveries significantly extended the known timeline of Maya writing, which had previously been thought to emerge closer to the Early Classic period. Instead, the San Bartolo evidence places the origins of Maya literacy several centuries earlier, aligning it with other early writing traditions in Mesoamerica. The presence of writing at this stage indicates that the Maya were already engaged in recording ritual, political, or mythological information in durable visual forms, contributing to the broader development of script systems in the region.
