Cooperative Action of Hunter-Gatherers in the Early Neolithic Near East. A View from Göbekli Tepe

Just back from this year´s Warfare, Environment, Social Inequality and Peace Studies (WESIPS) Conference in Seville, organized by Richard and Yamilette Chacon at the Center for Cross-Cultural Study (Spanish Studies Abroad). After a very inspirational conference and a stay in a very nice city, I thought I´d share a (very) short version of my talk. So here it comes.


The last post-Ice Age hunter-gatherer communities of the Near East have long been seen as loosely organized and low-hierarchical. The last decades of research have revealed a number of sites which considerably change this image. Nearly every site excavated at the appropriate scale shows a spatial division of residential and specialised workshop areas, and special buildings or open courtyards for communal and ritual purposes. Thus there is strong evidence for a degree of social complexity that was hitherto quite unsuspected.

While there is continued dispute over the question of organized warfare in the earliest Neolithic of the Near East, recent research has provided clear evidence of inter-personal and probably inter-group violence and beginning social inequality. But there are also signs of evolving strategies for conflict mitigation and cooperation. A key site to understand this aspect of early Neolithic social practises is Göbekli Tepe, a mountain sanctuary in southeastern Turkey.

Göbekli Tepe is situated on the highest point of the Germuş mountain range overlooking the Harran plain. The site lies on an otherwise barren limestone plateau. The tell has a diameter of around 300 m and is characterized by several mounds divided by depressions. At the highest point, Göbekli Tepe has about 15 m of stratigraphy. Work at the site started in 1995 under the direction of  Klaus Schmidt and concentrated in the first ten years in the southeastern depression. Starting from 2007 further excavation areas were opened on the soutwestern and nortwestern hilltop, and in the northwestern depression.

All areas excavated so far show a similar general stratigraphic sequence. The oldest layer III is characterized by monolithic T-shaped pillars, which were positioned in circle-like structures. The pillars were interconnected by limestone walls and benches leaning at the inner side of the walls. In the centre of these enclosures there are always two bigger pillars, with a height of over 5m. The circles measure 10-20m. This layer dates to the Pre-Pottery Neolithic A and maybe reaches the earliest PPN B, between 9600-8800 in absolute dates. The buildings of layer III were intentionally beckfilled at the end of their uselifes. Layer III is supraposed by layer II, dating to the early and middle PPNB, the time between 8800-8000 cal BC. This layer is characterised by smaller, rectangular buildings. The number and the height of the pillars are also reduced.

The most impressive element of Göbekli Tepe´s architecture are the T-shaped pillars. The T-shape is clearly an abstract depiction of the human body seen from the side. Evidence for this interpretation are the low relief depictions of arms, hands and items of clothing like belts and loinclothes on some of the central pillars. There is a clear hierarchy of pillars inside the enclosures. The central pillars are up to 5,5 m high, they have the already described anthropomorphic elements. The surrounding pillars are smaller, but more richly decorated with animal reliefs than the central ones. They are always „looking“ towards the central pillars, and the benches between them further amplify the impression of a gathering of some sort. The input of work in the constructions seems enormous.

At Göbekli Tepe, the Neolithic quarry areas are well known. They lie on the limestone plateau immediately adjacent to the site. The maximum distances that had to be covered were 600-700m. However, the terrain is uneven and sloping upwards, and the megaliths are of impressive size. The input of manpower seems pretty high.

And another aspect is of importance. It seems that the enclosures were never really finished. There is permanent construction, deconstruction, and reconstruction activity at Göbekli Tepe, and the intensity of work indicates something else than pure maintenance. Most likely the act of working at the site was central to the builders, and repeated periodically, whether or not a real need existed. For example, in the inner ring of Enclosure C there is barely one pillar standing in its original position.

As Göbekli Tepe has no traces of settlement, there is no possibility of a direct evaluation of the number of people present on-site. If we turn to ethnographic data, core group sizes of 25-50 persons for fully mobile hunter-gatherers, and a little higher numbers for semi-sedentary residential groups are suggested. The number of people one group could spare for construction work of the amplitude visible at Göbekli Tepe is definitely too small. It seems possible that several groups had to collaborate for a period of time to carry out building activities and to supply for the builders. And there actually is vast evidence for people congregating at Göbekli Tepe.

An answer to the question why these people congregated for work at Göbekli Tepe comes from the enclosure´s fillings. The material used as backfill consists of limestone rubble from the quarries nearby, flint artefacts and animal bones smashed to get to the marrow, clearly the remains of meals. Enclosure D alone, the largest of the four circles, comprised nearly 500 cubic meters of debris. As traces of permanent settlement are absent, this readily leads to the idea of large, ritualized work feasts rooted in the belief systems of the people congregating there. This concept was explored in-depth by Dietler and Hayden and provides a good working hypothesis to explain the at least temporary supra-group cohesion generated for collective work.

Archaeozoological data further strengthens the image of large feasting events at certain times of the year. At Göbekli, Gazelle is the major meat animal [external link]. As this species is migratory, a large scale supply of meat was possible in late autumn, when there would also be rain water available after the long, dry summer. The second important species is aurochs, an animal all year round available in the meadows surrounding the Germus mountains. A single auerochs can provide enough meat for a smaller group of people. Of course both sources could have been used supplimentarily. But why hunt dangerous aurochs when there is an abundance of Gazelle? It seems more likely, that aurochs was targeted at occasions different from the work feasts, and maybe more related to the enclosures´ functions which seem to be related to distinct groups of people.

The enclosures excavated so far show a variation in the animal species depicted prominently in the iconography of each circle. While in Enclosure A the snake prevails, in Enclosure B foxes are dominant, for example. In Enclosure C boars take over and in Enclosure D birds are playing an important role, while Enclosure H has lots of wildcats. Interpreting these differences as figurative expression of community patterns could probably hint at the different groups building the particular enclosures.  The character of these entities remains open to discussion at the moment. There are some clues however. Restriction of the access to knowledge and participation in rituals seems to be attestable at Göbekli Tepe. On a general level, some object classes known from settlements are missing. For example, awls and points of bone are nearly completely absent. The tasks carried out with them probably were not practiced here, and it may well be that the part of the population carrying them out was absent, too. Further, clay figurines are absent completely from Göbekli. This observation gains importance in comparison to Nevalı Çori, where clay figurines are abundant, missing only in the ‘cult building’ with its stone sculptures and T-shaped pillars very similar to Göbekli Tepe. Clay and stone sculptures may thus well form two different functional groups, one connected to domestic space (and cult?) and one to the specialized ‘cult buildings’ – and to another sphere of ritual also evident at Göbekli Tepe. Its iconography is exclusively male.

The pillars are often richly decorated. But in some cases, the imagery obviously is going far beyond mere decoration. The narrative character of several depictions in flat relief is underlined by Pillar 43, whose whole western broad side is covered by a variety of motifs. This could be a hint to one aspect of the enclosure´s functions – as a repository for tales, maybe myths crucially important to the groups building them. It is also possible to identify the general theme these stories – and the enclosures – are related to. A recurring motif on reliefs is human heads between animals, or, as already seen on pillar 43, headless humans. The special treatment and the removal of skulls is well-attested for the PPN death ritual. A connection with death or ancestor cult of Neolithic groups seems to be the most probable function of Göbekli Tepe´s enclosures. With their rich decoration, they are monuments in stone of important aspects of these groups´ identities, which were reinforced during ritually repeated events that included feasting.

To conclude, it seems that at Göbekli Tepe we see several social phenomena interact. Religious belief generated a need for constant costly building activity, which could only be accomplished by cooperation, possibly of members of different groups. Cooperation was ensured by large work feasts, that produced social cohesion. These groups reinforced their identities through – most likely – unpleasant initiation rituals held within the circular buildings. The character of these groups, marked by emblematic animals and important aspects of mythology carved and preserved in stone, remains unclear at the moment. Clans or tribes would be a possibility, but also other organizational structures, that cross-cut those based on ancestry are a distinct possibility. As only male hunters become visible at Göbekli Tepe, and exclusion as well as initiation seem to have played a major role, secret societies are another possibility. Festing and ritual thus emerge as major incentives for cooperative action during the earliest Neolithic.

    Fascinating reading Oliver, many thanks.

    When you note how, “Religious belief generated a need for constant costly building activity, which could only be accomplished by cooperation,” and the evidence (i.e. headless human, skulls) suggestive perhaps of a death cult of sorts within the T-shaped pillar spaces, I am reminded a little of the mimetic theory of Rene Girard. I’m curious if his theory could be, in any sense and to any degree, applied to Gobekli Tepe?

    Girard was of the opinion that ‘sacred violence’ had been essential in the formative constitution of human culture and social order: in the sense that “sacrificial religion” acted as an early cultural mechanism for controlling intra-community violence (arising from so-called “mimetic rivalry” or rather the instinctive tendency within humans to imitate what other others desire and enter into conflict with them over it), through a kind of ritualized scapegoating.

    In simple terms, he thought that emissary victimage or scapegoating set up the first condition for archaic collective identity-bonding i.e. “we’re all one and united against, and by virtue of, the scapegoated Other” which resulted in a ‘sacralization’ of the dead victim, viewed paradoxically as the guilty origin of the original crisis (“he must have been guilty or we all wouldn’t have killed him”) and equally as the miraculous herald of social peace, at which point the ‘deified victim’ becomes the cultic focus of society.

    This seems to me to be not all that dissimilar from Schmidt’s idea that, “first came the temple, then the city” if one understand ‘temple’ to mean death rituals.

      Thanks for your kind words. It´s really interesting that you mention Girard´s mimetic theory – we have a paper upcoming that explores its applicability to GT in detail (Lee Clare is the lead author). I´ll be sure to post something here when the paper is out.

      • Sean Murphy

        Thanks for the swift reply Oliver, I’m really looking forward to reading your post about this paper!

  2. Trevor

    That’s a great piece of work, Oliver. I hope that you had time in the conference paper to ‘unpack’ that final paragraph. And I also hope that you will be publishing a fuller version. I particularly liked the diagram at the top of your piece, with its two, complementary processes whereby group cohesion and collective identity were maintained. I also agree with you strongly when you emphasise the repeated symbolic performances of construction, re-construction, re-modelling etc. Whether one thinks of the individual enclosure and its complex history (about which you know more than the rest of us) or of the accumulation of enclosures over centuries, it is clear that repeated performance is central to the purpose of Göbekli Tepe.I was reminded of some stuff that I had written, but which has been “in press” for too long. I have concluded a chapter for a book on Play, Ritual and Belief with the paragraph:
    What is most striking about the evidence of ritual practice as I have sketched it is its concern with making and re-making buildings, sculptures, figurines, signs or paintings, rather than with religious ceremonies taking place in those buildings, or before those images. This suggests that the repeated performances of making and re-making buildings, of feasting, or of interring bodies within the settlement, were themselves the ritual performances essential to the forging of collective memory and the sustaining of collective identity. Their repetition was important because it necessarily involved remembering, and at the same time it mediated the transmission of meaning down the generations. And those rituals that were religious (that is, rituals that involve the presumption of supernatural agents) illustrate the point that shared religious practice is the basis of making shared religious belief, to the extent that the making and installing of a sculpted stone image may be understood as the making of belief – truly make-believe, which is where the social play of children and ritual meet.
    Thanks again for your telegram – most stimulating.

    • Oliver

      Thank you for your kind words. The aspect of constant work within and re-modeling of the enclosures is best documented for Enclosure C right now due to the work of Katja Piesker – she has published an extensive paper in German on this (Piesker, K. 2014. Göbekli Tepe-Bauforschung in den Anlagen C und E in den Jahren 2010 und 2012. Zeitschrift für Orient-Archäologie 7: 14-54.). Some of the thoughts presented in this ‘telegram’ will be published in a volume resulting from a session at last year´s EAA meeting, I hope that I will have the time to write something more about the conclusions expressed in the diagramm for the upcoming WESIPS volume.
      I would very much like to read and cite your paper – please let me know when it is published!

      It is possible that any feasting and drinking was related to special cosmological/astrological events. The benches may indicate a council circle (of clan heads) with the use of beer as participation in a sharing of “spirits.” A similar council circle was found in the Americas with the use of the pipe (and the stimulant of tobacco as a plant that contained spirits). The smoke from the Bowl of the pipe represented the ascension of the spirits from a hole in the ground to the sky.

      • Oliver

        Ethnographic data certainly offers a lot of possibilities to archaeologists – possibilities hard to prove in many cases.

      • Cliff

        Yes, difficult to prove. We can attempt to prove that gestures signs were used as a basis for depicted sign language. We know the historical meaning of hundreds of signs and when they are incorporated into a composition we can attempt to read them. If we follow the, discovered, rules for their organization this should result in logical messages as opposed to nonsense. This is, of course, only an indirect proof but much better than nothing. The signs can be tested against their context and unknown signs can be determined through known contexts.

        To date some differences have been found in signs that relate to differences in flora and fauna in different geographical areas. Still, a bull is a bull despite differences in species. Ingestion of plants that are psychotropic could, generally, be interpreted as containing spirits.

        After reading hundreds of ancient compositions we are able to gain some understanding of the basic cosmological premises of various ancient cultures. It appears that different aspects of a broad. underlying cosmology were emphasized at different times and places.

        The very existence of an ancient non-linear communicative system and the manner in which it reflected a world view may have significant psychological importance. We are not starting from scratch when we use gesture signs as a research tool. Gesture signs provide a foundation not only for research but also as a way to counteract total subjectivity when approaching ancient compositions.

        • Oliver

          Human cultures develop very differently in time and space. Ethnographic evidence therefore is always tentative, it highlights possibilities of interpretation.

  3. Casual Visitor

    Considering Pillar 43, some parts of it are still obscured behind the enclosure wall (left of Scorpio). Same is true with Pillars 21 and 22. Do you have any plans to explore the still hidden details of those particular pillars in the nearby future, or not ? Or perhaps these would remain hidden indefinitely ?

    • Oliver

      To explore the rest of the reliefs would mean to destroy Neolithic walls. This is not planned in the near future, no.

    Hi Oliver,

    You mentioned late autumn as an ideal seasonal congregation time when would be enough meat and rainwater. But wouldn’t the nearby Orencik village mucid stream have provided a lot more (and likely seasonal) water in the 10th millennium. Also, doesn’t the published archaeo-zoological data conclude August/September from the gazelle bone feasting? Gazelles compete with humans for pistachio which still ripen in Urfa from late August – so hunting them has an added benefit (and pistachio is heavily represented in the carbon dated remains on site)


    • Oliver

      Lang et al. 2013: 425 say “If the zooarchaeological and stable isotope data allow us to postulate that mid-summer till autumn may have been the preferred season for larger groups of hunter-gatherers to visit Göbekli Tepe, it might well be that this choice was deliberate: at this time of the year staples essential for human survival, particularly (wild) cereals and pulses, had already been harvested, while in the southern Anti-Taurus piedmont, almonds and pistachios – evidenced in the archaeobotanical record – must have been available in quantities. This highly nutrient food likewise attracted human groups and a variety of herbivores and omnivores, and possibly the headwater region of the Balikh witnessed considerable game density during mast availability.”
      I added that the availability of rainwater may speak in favor of autumn, as there are no springs at GT, but instead cisterns for collecting rainwater. The stream near Örencik today is not really a stream during dry summers, geology/palaeogeography will have to tell if (a) it was there during the PPN, and (b) if it was seasonal back then.

  5. stef

    Tks Oliver..

    I didn’t see this reply earlier..

    Its easier to talk in specific months because I think that Lang et al article attributes mid-summer to August and October to the beginning of Autumn – whereas most people think of autumn starting in September. Has any further zoo-archaeological data confirmed their conclusion or added to your view of (October/November).

    Who is working on the paleogoegraphy of the area and whether there were more abundant karstic spring back then with a likely much higher water table?

    all best,

    • Oliver

      Final report on archaeozoology by the München team is upcoming. We have a collaboration with Free University Berlin for Palaeogeography, their work starts this year.

      • stef

        cheers 🙂
