Fragments were found at the San Bartolo Archaeological Site in the northern woods. GuatemalaIt became famous in 2001 with the discovery of a burial chamber with colorful murals dating back to 100 BC depicting Mayan rituals and mythology.

Parts with a “7 video” glyph were found inside the same pyramid in Las Pinuara, where there were still intact murals.

As in the case of this structure, the Mayans often built modest temples first, and later larger versions on top of the former. The height of this pyramid reached about 30 meters.

The glyph found on the murals of “7 deer”, one of the 260 names on the calendar, was written by the ancient Mayan for the number seven above the outline of the deer’s head.

David Stuart, a professor at the University of Texas and the lead author of the findings, published in the journal Science Advances, described the fragments as “two small white plasters once plastered on a stone wall.”

“The wall was deliberately destroyed when the ancient Mayans rebuilt their ritual spaces – it turned into a pyramid.

“The paintings from this stage are all very fragmented, unlike the later and more popular chambers,” the Texas researcher said. By far the oldest notation of the Mayan calendar is from the 1st century BC

The calendar is rooted in observations of the movements of the sun, moon, and planets, and is based on a ritual cycle of 260 days each.

The 260-day calendar, called tzolk’in, is one of several Mayan timekeeping systems that work together, and includes the 365-day solar year, a large system called the “large number”, a lunar.

The calendar and the first examples from San Bartolo are one of the achievements of a culture that developed a writing system with 800 glyphs. The Mayans built temples, pyramids, palaces and observatories and engaged in modern farming without the use of metal tools or wheels.
