Painted Aztec snake carving found in Mexico City

Published

Archaeologists from the National Institute of Anthropology and History (INAH) have uncovered a painted Aztec snake carving in the Mexica capital of Tenochtitlan.

Tenochtitlan was situated on a raised islet in the western side of Lake Texcoco, which is now the historic part of present-day Mexico City.

The altepetl (city) was founded by the Mexica, a Nahuatl-speaking indigenous people of the Valley of Mexico, who entered the Basin of Mexico after the decline of the Toltec civilisation. The Mexica transformed the islet using the chinampa system, creating rectangular areas of fertile arable land to grow crops on the shallow lake beds.

The settlement experienced rapid growth, evolving into a formidable city-state and becoming an integral part of the Triple Alliance alongside Texcoco and Tlacopan.

Upon the arrival of the Spanish conquistadors in the year 1519, Tenochtitlan had reached its zenith, boasting an estimated population ranging from 200,000 to 400,000 residents.

The inhabitants were swiftly exposed to diseases for which they had no natural immunity. This devastating outbreak led to a significant population decline, with estimates indicating that over 50% of the region’s people fell victim to smallpox.

Recent excavations at the former School of Jurisprudence of the UNAM, located in the Historic Centre of Mexico City, have uncovered an Aztec snake carving at a depth of 4.5 metres beneath current street level. The carving measures 1.8 metres long by 1 metre tall, which according to the researchers was found outside its original context along with numerous architectural elements.

Due to the conditions in the soil, the stucco and polychromy traces of ochre, red, blue, black and white pigments have survived which cover over 80% of the carving. The researchers have used a humidity chamber to stabilize the pigments, which will undergo further sophisticated methods of preservation into 2024.

Barajas Rocha, who led the colour conservation work on the monolith of the goddess Tlaltecuhtli, explained that the process is crucial for the preservation of the polychromy, since, “these pigments , which represent a typical example of the colour palette that the Mexica used to decorate their cult images and their temples, are extremely fragile due to the mineral and plant materials from which they were obtained.”

Archaeologists excavate medieval timber hall

Archaeologists from the University of York have returned to Skipsea in East Yorkshire, England, to excavate the remains of a medieval timber hall.

Recent excavations unearthed a timber hall measuring 5 metres wide by 16 metres long, which was surrounded by a large ditched enclosure.

The size and shape of the hall is marked by post holes, which the team plan to excavate further to provide new insights into the hall’s purpose and setting in the surrounding landscape.

The hall sits adjacent to a 13-meter-high mound, once presumed to be a motte and bailey castle. However, carbon dating has since revealed its age to be 1,500 years prior to the Norman Conquest era from during the Iron Age.

Dr Jim Leary, from the University of York’s Department of Archaeology, said: “The unearthing of timber buildings dating to the period between the collapse of the Roman Empire and the arrival of the Vikings, a time often referred to as the Dark Ages, is an incredibly rare and significant find.

“The discovery at Skipsea is particularly interesting because we know that the area was in the hands of the last Anglo-Saxon King of England, Harald Godwinson, and then later, after the Norman Conquest of 1066, it became the estate centre of the Lords of Holderness.”

Skipsea was once home to three freshwater lakes, Skipsea Bail Mere, Skipsea Low Mere, and Skipsea Withow Mere, linked to the River Hull through a network of tributaries. These lakes (long-vanished), began 10,000 years ago during the Mesolithic period, and continued into the medieval period.

The lakes were a constant draw to population groups throughout history, which has provided archaeologists with Mesolithic stone tools, animal remains, bone harpoons, and Bronze Age buildings and trackways.

Archaeologists find traces of Gloucester’s medieval castle

Published

Archaeologists from Cotswold Archaeology have uncovered traces of Gloucester’s medieval castle in Gloucester, England.

The castle was first constructed during the Norman period as a simple motte and bailey. Over the centuries, various additions and periods of reconstruction extended the footprint of the castle, which by the 13th century became a royal residence for nobility and English kings.

Between the 15th century and 17th century, the castle went into decline and much of the stonework from the fortifications were used to construct roads and buildings within the city centre, leaving only the keep which was used as a gaol (prison).

In time, the keep was considered to be unsuitable and its demolition began in 1787, leaving no visible remains of the castle.

During development works in the south-west of Gloucester city centre, archaeologists from Cotswold Archaeology have uncovered traces of the castle beneath the basketball court of the former HMP Gloucester.

A number of trenches revealed medieval structural remains that archaeologists have interpreted as forming part of a masonry causeway or bridge structure. This provided access to the castle across its inner defensive ditch and continued north-east onto Castle Lane.

Excavations also found subsequent demolition and robbing of stonework, evidenced by the infilled castle ditch, and comprised cultivation soils of the Castle Gardens, which occupied this area from the later 18th century through to the mid-19th century.

In addition, a stretch of Post-medieval wall relating to the gardens was identified, which corresponds to a boundary shown on early and mid-19th century maps.

According to the archaeologists: “The results highlight that significant archaeology continues to survive at a relatively shallow depth, enabling us to trace historic land use and landscape change within this part of the city across many centuries.”
