The ruins of San Bartolo, Guatemala, contain a sample of the Sub-V phase. The approximately 4-m high Sub-V Maya hieroglyphic writing dating to the Late Preclassic platform extends 28 x 12 m at its base and supported three period (400 BC to 200 AD). The writing appears on separate masonry rooms. The 2005 excavations established preserved painted walls and plaster fragments buried that its central room was richly decorated and painted with within the pyramidal structure known as “Las Pinturas,” polychrome murals. The surviving doorjamb bears a colorful which was constructed in discrete phases over several image of the Maize God, who is a central character in the centuries. Samples of carbonized wood that are closely mythological scenes of the later Room 1 murals (4). The line associated with the writing have calibrated radiocarbon of script was possibly associated with this religiously themed dates of 200 to 300 BC. This early Maya writing implies scenery, but its original placement within the room is that a developed Maya writing system was in use uncertain. centuries earlier than previously thought, approximating We obtained accelerator mass spectrometry (AMS) a time when we see the earliest scripts elsewhere in radiocarbon dates on five charcoal samples from sealed . deposits in the three architectural strata (Sub-VI, Sub-V, and Sub-IV) in order to bracket the age of the painted blocks (Fig. Research on the origins of Maya hieroglyphic writing has 3). The first of these, from within the floor of the Sub-VI long been hindered by the paucity of good archaeological platform, the construction phase that was encapsulated by contexts and reliable dates for inscribed artifacts and Sub-V construction, provides a maximum uncalibrated monuments. With a few exceptions, examples of archaic radiocarbon date of 2260±40 BP (400 - 200 BC; 2 sigma appear on illicitly excavated objects that can be [95% probability] calibrated range) (fig. S1). A sample from stylistically dated to no earlier than about 100 BC -100 AD, within the floor of Sub-V dates the construction of the room when writing seems to have been already well-established at 2200±60 BP uncalibrated (390 - 80 BC; 2 sigma [95% elsewhere in Mesoamerica.

Taken in concert, these samples most of this important mural, dating to approximately 100 BC and those analyzed in association with the final two phases of (1–4) (figs. S6 to S10).
