Lost Maya city discovered in Mexican forest

Published

on

Archaeologists from the National Institute of Anthropology and History (INAH) have announced the discovery of a previously unknown Maya city in the forests of the Balamkú ecological reserve in the Mexican state of Campeche.

The city has been called Ocomtún, meaning “stone column”, by the researchers due to numerous cylindrical stone columns that have been uncovered throughout the city interior.

Archaeologists made the discovery as part of a project to document and map unexplored areas of central Campache using high resolution photography and Light Detection and Ranging (LiDar).

LiDar is a method of remote sensing using light in the form of a pulsed laser to measure ranges (variable distances) to the Earth. The differences in the laser return times and measurements of the wavelengths can be used to compile a 3-D digital map of the landscape, removing obscuring features such as tree canopies that could hide archaeological features.

The survey project revealed a nucleus of pre-Hispanic structures located on a peninsula and surrounded by wetlands. The site covers an areas of around 123.5 acres and mainly dates from around the Classic Period (AD 250-1000).

Various large buildings have been confirmed through a ground level inspection, including several pyramidal structures that are over 15 metres in height, plazas, elongated structures arranged in a concentric circle plan, and evidence of a ball game court.

A large causeway connects the southeastern part of the site to a cluster of buildings in the northwest where an 80 metre long rectangular acropolis is situated, along with a pyramid that rises 25 metres in height.

According to the researchers, the city underwent several alterations in the Terminal Classic period (AD 800-1000) with the construction of shrines, terraces and plazas that were used for ceremonial rituals.

By the 10th century AD, the population declined and the site was abandoned around the time of the Maya collapse, a period that saw the abandonment of many Maya cities in the southern Maya lowlands.

Megathrust earthquakes possible cause of Teōtīhuacān decline

Published

A new study, published in the journal Science Direct, suggests that a series of megathrust earthquakes led to the decline and possible abandonment of Teōtīhuacān.

Named by the Nahuatl-speaking Aztecs as Teōtīhuacān, and loosely translated as “birthplace of the gods”, Teōtīhuacān is an ancient Mesoamerican city located in the Teōtīhuacān Valley of the Free and Sovereign State of Mexico, in present-day Mexico.

The development of Teōtīhuacān can be identified by four distinct consecutive phases, known as Teōtīhuacān I, II, III, and IV.

It was during phase II (AD 100 to 350) that the city population rapidly grew into a metropolis and saw the construction of monuments such as the Pyramid of the Sun (the third largest ancient pyramid after the Great Pyramid of Cholula and the Great Pyramid of Giza), the Pyramid of the Moon, the Avenue of the Dead, and the Ciudadela with the Temple of the Feathered Serpent (also known as Temple of the Quetzalcoatl).

An analysis of several pyramids within the city has revealed evidence of Earthquake Archaeological Effects (EAEs), potentially linked to seismic loading. The study has focused on the Temple of the Feathered Serpent (Old temple and New temple), and the Sun and the Moon pyramids, in which visible EAE’s can be observed.

According to the researchers, the EAE’s are likely caused by megathrust earthquakes, for which five destructive ancient earthquakes have been estimated to have struck Teōtīhuacān between the Tzacualli – Miccaotli (AD 100–150), and Metepec (AD 600 ± 50) stages, by matching EAEs and archaeological dates.

Based on the spatial pattern of the EAEs and the orientation of the dipping broken corners (DBC) or chip marks, it is theorised that a series of seismic shocks struct the city from the SW to the NE, indicating a possible origin of a seismic source in the Middle American Trench caused by repetitive megathrust earthquakes.

At least, two strong destructive earthquakes (Intensity VIII-IX) affected Teōtīhuacān in antiquity that impacted the development of the architectural styles. The first one occurred between the years AD 1–150 (Miccaotli phase), and the second one occurred in AD 455 ± 50 (Late Xolalpan-Early Metepec phase).

This was followed by three further damaging earthquakes, for which the latter two occurred around AD 650 before the abandonment of the city the following century.

“This proposal does not conflict with other existing theories for the Teotihuacan abrupt collapse, considering that the sudden overlapping of natural disasters like earthquakes could increase internal warfare (uprising), and civil unrest,” said the study authors.

Excavations uncover traces of Kraków Fortress

Published

A team of archaeologists conducting archaeological works at the S52 construction site have uncovered traces of the Kraków Fortress in the Polish city of Kraków.

S52 is a Polish highway being constructed in the Silesian and Lesser Poland voivodeships, which upon completion will connect the border of the Czech Republic in Cieszyn with Kraków.

Kraków Fortress refers to a series of Austro-Hungarian fortifications constructed during the 19th century. The fortress included the 18th century Kościuszko Insurrection fortifications, the medieval Wawel Castle, and the Kraków city walls. Of the over 50 post-Austrian forts in Krakow, 44 structures have been preserved in their entirety or with minor changes.

Excavations in the area of ​​the northern bypass of Krakow have revealed the remains of earthen structures related to the network of military units being established around the city, whose task was to turn Krakow into a modern border fortress.

The team also uncovered traces of earth embankments and moats, as well as the infrastructure for draining rainwater from the infantry entrenchment area and a wooden shelter from a dugout measuring 25 by 7.5 metres.

A press statement by the Republic of Poland, said: “During the research, objects related to the everyday life of soldiers were discovered. These include a tin enameled mug with a signature on the bottom depicting a double-headed imperial eagle with the inscription Austria and the initials H&C 1/2.”

“The preserved marking allowed us to determine that the mug is a product of the Haardt & Co. factory located in Knittelfeld, Austria. Enamellierwerke und Metallwarenfabriken AG. Founded in 1873 by Friedrich Wilhelm Haardt, the factory produced embossed enamelled dishes, including orders for the then Austrian army.”
