Tell Abu Hureyra

Location and description

Abu Hureyra is a tell, or ancient settlement mound, in modern-day Raqqa Governorate in northern Syria. It is on a plateau near the south bank of the Euphrates, 120 kilometres (75 mi) east of Aleppo. The tell is a massive accumulation of collapsed houses, debris, and lost objects accumulated over the course of the habitation of the ancient village. The mound is nearly 500 metres (1,600 ft) across, 8 metres (26 ft) deep, and contained over 1,000,000 cubic metres (35,000,000 cu ft) of archaeological deposits. Today the tell is inaccessible, submerged beneath the waters of Lake Assad.

Occupation history

First occupation (c. 11,300-9,400 BP)

The village of Abu Hureyra had two separate periods of occupation: An Epipalaeolithic settlement and a Neolithic settlement. The Epipaleolithic, or Natufian, settlement was established c. 13,300 years ago and lasted until 11,400 BP. During the first settlement, the village consisted of small round huts, cut into the soft sandstone of the terrace. The roofs were supported with wooden posts, and roofed with brushwood and reeds. Huts contained underground storage areas for food. The houses that they lived in were subterranean pit dwellings. The inhabitants are probably most accurately described as "hunter-collectors", as they didn't only forage for immediate consumption, but built up stores for longterm food security. They settled down around their larder to protect it from animals and other humans. From the distribution of wild food plant remains found at Abu Hureyra it seems that they lived there year-round. The population was small, housing a few hundred people at most—but perhaps the largest collection of people permanently living in one place anywhere at that time.

The inhabitants of Abu Hureyra obtained food by hunting, fishing, and gathering of wild plants. Gazelle was hunted primarily during the summer, when vast herds passed by the village during their annual migration. These would probably be hunted communally, as mass killings also required mass processing of meat, skin, and other parts of the animal. The huge amount of food obtained in a short period was a reason for settling down permanently: it was too heavy to carry and would need to be kept protected from weather and pests.

Other prey included large wild animals such as onager, sheep, and cattle, and smaller animals such as hare, fox, and birds, which were hunted throughout the year. Different plant species were collected, from three different eco-zones within walking distance (river, forest, and steppe). Plant foods were also harvested from "wild gardens" with species gathered including wild cereal grasses such as einkorn wheat, emmer wheat, and two varieties of rye. Several large stone tools for grinding grain were found at the site.

Abu Hureyra 1 had a variety of crops that made up the system. Their resources consisted of 41% Rumex and Polygonum, 43% rye and einkorn, and the remaining 16% lentils.

Depopulation

After 1,300 years the hunter-gatherers of the first occupation mostly abandoned Abu Hureyra, probably because of the Younger Dryas, an intense and relatively abrupt return to glacial climate conditions which lasted over 1,000 years, or because of the purported impact event. The drought disrupted the migration of the gazelle and destroyed forageable plant food sources. The inhabitants might have moved to Mureybet, less than 50 km to the northeast on the other side of the Euphrates, which expanded dramatically at this time.

Second occupation (ca. 8,600–5,800 BCE)

The second occupation covers a period from ca. 10,600–7,800 cal BP in the Neolithic. In comparison to Abu Hureyra 1, Abu Hureyra 2 had a different accumulation of resources, consisting of 25% Rumex/Polygonum, 3.7% rye/einkorn, 29% barley, 23.5% emmer, 9.4% wheat-free threshing, and 9.4% lentils.

It is from the early part of the Younger Dryas that the first indirect evidence of agriculture was detected in the excavations at Abu Hureyra, although the cereals themselves were still of the wild variety. It was during the intentional sowing of cereals in more favourable refuges like Mureybet that these first farmers developed domesticated strains during the centuries of drought and cold of the Younger Dryas. When the climate abated about 9500 BCE they spread all over the Middle East with this new bio-technology, and Abu Hureyra grew to a large village eventually with several thousand people. The second occupation grew domesticated varieties of rye, wheat and barley, and kept sheep as livestock. The hunting of gazelle decreased sharply, probably due to overexploitation that eventually left them extinct in the Middle East. At Abu Hureyra they were replaced by meat from domesticated animals. The second occupation lasted for about 2,000 years.

Abu Hureyra 2 was broadly contemporary with Körtik Tepe and Tell Mureybet.

Transition from foraging to farming

Some evidence has been found for cultivation of rye from 11050 BCE in the sudden rise of pollen from weed plants that typically infest newly disturbed soil. Peter Akkermans and Glenn Schwartz found this claim about epipaleolithic rye, "difficult to reconcile with the absence of cultivated cereals at Abu Hureyra and elsewhere for thousands of years afterwards". It could have been an early experiment that didn't survive and continue. It has been suggested that drier climate conditions resulting from the beginning of the Younger Dryas caused wild cereals to become scarce, leading people to begin cultivation as a means of securing a food supply. Results of recent analysis of the rye grains from this level suggest that they may actually have been domesticated during the Epipalaeolithic. It is speculated that the permanent population of the first occupation was fewer than 200 individuals. These individuals occupied several tens of square kilometers, a rich resource base of several different ecosystems. On this land they hunted, harvested food and wood, made charcoal, and may have cultivated cereals and grains for food and fuel.

The first domesticated morphologic cereals came about at the Abu Hureyra site around 10,000 years ago. Amongst the species found at the site, cereals such as rye and emmer wheat are predominant.

Agriculture

The village of Abu Hureyra had impressive agricultural advances for the time period. The rapid growth of farming led to the development of two different domesticated forms of wheat, barley, rye, lentils, and more due in part to a sudden cool period in the area. The cool period affected the supply of wild animals such as gazelle, which at the time was their main source of protein. Since their food supply became scarce it was critical that they find a way to provide for the population, this led to extensive agricultural efforts as well as the domestication of sheep and goats to provide a steady protein source. Another helpful factor was the ability to grow legumes, which fix nitrogen levels in the soil. This improved the fertility of the soil and allowed for the crop plants to flourish.

This massive increase in agriculture had a cost. Those who lived in the village of Abu Hureyra experienced several injuries and skeletal abnormalities. These injuries mostly came from the way the crops were harvested. In order to harvest the crops the people of Abu Hureyra would kneel for several hours on end. The act of kneeling for long durations would put the individuals at risk for injuring the big toes, hips, and lower back. There was cartilage damage in the toe that was so severe the metatarsal bones would rub together. In addition to this injury another common injury was for the last dorsal vertebra to be damaged, crushed, or out of alignment due to the pressure used during the grinding of grains. These skeletal abnormalities also can be found on the teeth of the Abu Hureyra people. Since the grain was stone ground many flakes of stone would still be left in the grain which over time would wear down the teeth. In rare cases women would have large grooves in their front teeth which suggests they used their mouth as a third hand while weaving baskets. This dates basket weaving as far back as 6500 BC and the fact so few women had these grooves shows that basket weaving was a rare skill to have. These baskets were extremely important to the success of the agriculture because the baskets were used to collect or spread seeds, and were also used to collect or distribute water.
