Study finds new information on food culture in world’s first cities in 3500 BC

Fresh evidence on the types of food people ate in the world’s first urban settlements has been revealed in a new study.

Mesopotamia, which is modern-day Iraq, saw the beginnings of cities which developed some 5,500 years ago.

No other artefact type is more symbolic of this development than the so-called Beveled rim bowl (BRB), the first mass produced ceramic bowl.

BRB’s function and what food(s) these bowls contained has been the subject of debate for more than a century.

In a paper, published in the Journal of Archaeological Science: Reports on Friday, new evidence showed that these bowls contained a variety of foods, but especially meat-based meals, most likely bone marrow flavoured stews or broths.

Chemical compounds and stable isotope signatures of animal fats were discovered in BRBs from the Late Chalcolithic site of Shakhi Kora, which is located in the Upper Diyala/Sirwan River Valley of north-eastern Iraq.

An international team led by Professor Claudia Glatz, of the University of Glasgow, has been carrying out excavations at Shakhi Kora since 2019.

Her work is part of the ongoing Sirwan Regional Project, which has been set up to explore the archaeological landscapes in and around the river known in Kurdish as the Sirwan and in Arabic as the Diyala in the Kurdish Region of Iraq.

This new information changes the traditional interpretation that these bowls were containers of cereal-based rations and bread moulds.

Inherently taxable and storable, cereal grains such as wheat, emmer, and barley, have long been considered the economic backbone and main source of wealth and power for early state institutions and their elites.

But the new paper, titled “Revealing invisible stews: New results of organic residue analyses of Beveled Rim Bowls from the Late Chalcolithic site of Shakhi Kora, Kurdistan Region of Iraq”, said: “Our analytical results challenge traditional interpretations that see BRBs as containers of cereal-based rations and bread moulds.

“The presence of meat and potentially also dairy-based foods in the Shakhi Kora vessels lends support to multi-purpose explanations and points to local processes of appropriation of vessel meaning and function.

BRBs are mass-produced, thick-walled, conical vessels that appear to spread from southern, lowland sites such as Uruk-Warka across northern Mesopotamia, into the Zagros foothills, and beyond.

The ancient clay bowls are found in their thousands at Late Chalcolithic sites, often associated with monumental structures.

Stylised BRBs appear on the earliest written documents, early cuneiform tablets, and are conventionally interpreted as ration containers used to distribute cereals or cereal-based foods to state-dependent labourers or personnel.

Professor Glatz, a professor of archaeology and director of the Shakhi Kora excavations, said: “Our results present a significant advance in the study of early urbanism and the emergence of state institutions.

“They demonstrate that there is significant local variation in the ways in which BRBs were used across Mesopotamia and what foods were served in them, challenging overly state-centric models of early social complexity.

“Our results point towards a great deal of local agency in the adoption and re-interpretation of the function and social symbolism of objects, that are elsewhere unambiguously associated with state institutions and specific practices.

“As a result they open up exciting new avenues of research on the role of food and foodways in the development, negotiation, and possible rejection of the early state at the regional and local level.”

Professor Jaime Toney, professor in environmental and climate science at the university’s School of Geographical and Earth Sciences, said: “We have been collaborating closely with Claudia and her team for several years to minimise contamination during the collection of vessels from archaeological sites and it is fascinating to see this pay off with the analysis of fossil residues and the stable isotope analysis clearly indicate that they once held animal fats.”
