Орчин үеийн 3D дүрслэлийн технологийн тусламжтайгаар Мексикийн Эль Пальмар дахь чулуун хөшөөнөөс Маяагийн соёл иргэншлийн “Урт тоолол” (Long Count) хуанлийн хамгийн эртний гэж үзэж буй огноог тайлж уншжээ.
Калифорнийн их сургуулийн (UC Davis) Кэничиро Цүкамото тэргүүтэй судлаачдын баг 46 дугаар хөшөө буюу Stela 46-г өндөр нарийвчлалтай сканнердаж, дижитал аргаар сэргээн босгосноор 2000 орчим жилийн турш элэгдэлд орж гэмтсэн бичээсийг тодруулсан байна. Судалгаагаар уг хөшөөн дээр МЭ 180 оны наймдугаар сарын 31-ний өдрийг тэмдэглэсэн байх магадлалтай гэж үзжээ. Энэхүү огноо нь өмнө нь хамгийн эртнийд тооцогдож байсан Тикаль хотын 29 дүгээр хөшөөний огнооноос зуу гаруй жилээр өмнөх үед хамаарч байгаа нь Маяагийн бичгийн соёл хэрхэн дэлгэрсэнийг ойлгоход чухал ач холбогдолтой юм.
Маяачууд цаг хугацааг өдөр тутмын амьдрал, хаант засаглал, шашны зан үйлтэй нягт уялдуулан, давхарласан системээр хэмждэг байв. 46 дугаар хөшөөн дээрх огнооноос гадна газар доорх ертөнцийн Ягуар бурхантай холбоотой удирдагчийн дүрслэл нь тухайн үеийн хаант засаглалын эрх мэдэл болон бурханлаг байдлыг илэрхийлдэг. Хэдийгээр чулуун хөшөө ихээхэн элэгдэлд орсон тул зарим судлаачид өөр огноог санал болгож байгаа ч, энэхүү олдвор нь Маяагийн хуанлийн систем нь сонгодог үеийн хаант засаглалын тогтвортой байдалд чухал үүрэг гүйцэтгэж байсныг баталж байна.

A badly weathered stone monument from El Palmar in Mexico may hold the earliest known Long Count calendar date ever found in the Maya lowlands. Carved on Stela 46, the inscription appears to record a date from 180 C.E., alongside imagery of a ruler linked to a Jaguar deity of the underworld. According to a study published in Ancient Mesoamerica, the reading only became possible thanks to modern 3D imaging techniques that revealed details the naked eye can no longer see.
Stela 46 has been sitting exposed for nearly 2,000 years, and its surface is heavily damaged. That erosion is exactly why earlier readings were difficult or incomplete. According to Kenichiro Tsukamoto of the University of California Davis and his team, only high-resolution scanning and digital reconstruction made it possible to pull out a readable sequence of glyphs from the stone.
How The Maya Measured Time In Layers
The Long Count calendar works like a stacked system of time units. It starts with single days and builds up into larger cycles, including the b’ak’tun, which spans about 400 years. Alongside it, the Maya also used a 260-day ritual calendar and a 365-day solar calendar, meaning time wasn’t just linear but layered and constantly cross-referenced.
According to the Ancient Mesoamerica study, parts of this system likely go back even earlier than the Maya themselves, possibly to the Olmec civilization that came before them in the region. That would explain why the structure feels so developed right from the earliest known inscriptions.
The system was decoded in the late 1800s by German librarian Ernst Förstemann, which finally allowed scholars to translate Long Count dates into modern calendars. One example often used is that even a familiar date like July 4, 1776 can be written in Long Count format, showing just how structured the system is.
Even if it sounds abstract, this calendar wasn’t just math. It was part of everyday political life, tied directly to kingship and ritual authority.
A Date That Changes the Historical Timeline
On Stela 46, researchers identified a Long Count sequence reading 8.7.1.0.0, which corresponds to August 31, 180 C.E., according to Kenichiro Tsukamoto and the study team. If correct, this would make it the earliest known Long Count inscription discovered in the Maya lowlands.
There is, however, some uncertainty. The stone is heavily damaged, and another possible reading, 8.7.0.5.0, has also been proposed. Both interpretations still place the inscription in roughly the same time period, but they highlight how fragile the evidence has become after nearly two millennia of erosion.
In either case, the inscription predates the next known example, Tikal Stela 29, which records a date equivalent to 292 C.E. This gap of more than a century is what makes El Palmar particularly significant for researchers studying the early spread of Maya calendrical writing.
“El Palmar Stela 46 and subsequent monuments suggest that the Long Count played a vital role in the continuity of kingship during the Classic period. Further study of this region will provide new insights into the emergence of Maya kingship,” said the study’s authors.
The monument also shows a ruler holding the head of a deity associated with the Jaguar god of the underworld. That kind of imagery shows up a lot in Maya art, usually tied to power, warfare, and divine legitimacy.
Rebuilding Worn Stone With Digital Tools
The only reason any of this is visible today is because of imaging work done on the monument. Researchers used photogrammetry and high-resolution 3D scanning to capture the surface in extreme detail, down to fractions of a millimeter.
As reported in the study, this allowed them to pick up faint carved lines that are no longer visible under normal lighting. Once digitized, the model could be lit from different angles on a computer, making shallow grooves stand out more clearly.
Even with all that, the reading isn’t 100% locked in. The erosion means parts of the glyphs are still open to interpretation, and the authors acknowledge that uncertainty.
