Pyramidal structures uncovered at Los Teteles de Ávila Castillo

Published

on

Archaeologists from the National Institute of Anthropology and History (INAH), and the INAH Puebla Centre, have uncovered several pyramidal structures at the Los Teteles de Ávila Castillo archaeological site.

Tetelictic, or “Los cerritos” as it is known locally, is located in the municipality of Teteles de Ávila Castillo in Mexico’s State of Puebla. The site is more than 3,000 years old and dates from the late Middle Formative period (600 BC).

According to a press announcement by INAH, Tetelictic was a place of pilgrimage for people from the Sierra Norte area, who later emigrated to around Teotihuacan, Cantona or Cholula.

Following a series of research projects since 2014, the site has been revealed to be a large ceremonial complex covering an area of 7.4 acres.

Archaeologists theorise that Tetelictic may have served as an astronomical observatory to record the agricultural cycle, as the entire urban complex appears to be aligned with mountain ranges from the surrounding landscape. The largest structure (designated Structure 1), also has an alignment with Canopus, the brightest star in the southern constellation of Carina.

The latest excavations have been conducted in response to both erosion and the structures being robbed by locals for construction material. This has led to three pyramidal structures being uncovered, accompanied with charred ceramics, polished lithics, and carved objects made from obsidian and basalt.

Experts suggest that that obsidian flakes found throughout Tetelictic are indicative of an obsidian lithic industry for the manufacturing of products and weapons.

Mario Castro Jiménez, president of the Tzoncoyotl civil association, said: “The following seasons – we will focus on knowing the construction and architectural systems of the pyramidal bases. The archaeological site will remain closed to the public until the corresponding authorities determine otherwise.”

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.”
