Deciphering a meal at Göbekli Tepe (part 1)

This short post is meant to introduce myself, Laura, as a new member of the Göbekli Tepe project team. I am an archaeologist doing research into the Neolithic and Bronze Age from the Levant to the Carpathian Basin with a focus on the archaeology of food and conflict. Exploring the preparation of vegetable meals in Göbekli Tepe and inferring the social dimensions of vegetable food is part of my project during the next three years.

Göbekli Tepe has a big potential for such studies. Not only is there a vast material culture related to food processing (grinding stones, pestles, mortars, sickles etc.), but food, and also vegetable food, seems to have had a special place in the worldview of its builders. Here is a little teaser.

In 2008, during the excavation of the final layers of Enclosure C, a special discovery was made. A wild boar and two stone platters lie in front of one of the central pillars of Enclosure C. The sculpture is around 30 cm high; its length is almost 50 cm. Both platters are similarly large, with diameters of 47 and 50 cm. They have been intentionally perforated in the middle; other similar finds from the site are usually unperforated. Strike marks are obvious around the perforation. Their surface is very well smoothed, although the northern platter is better worked than the southern one. Both platters are round with slightly convex surfaces down to the perforation. The wild boar is sitting with his mouth on the platters, somehow slightly oblique, its neck oriented to the hole.The platters don’t sit directly on the ground, but suprapose other stone vessels. Several more wild boar sculptures and reliefs are known from Enclosure C.  All of them are part of one bigger ensemble surrounding the central pillars – and this ensemble clearly shows strong links to the preparation of food.

We are only at the start of deciphering the multiple layers of meaning inherent in the buildings of Göbekli Tepe. So stay tuned for more as I start as we begin to unveil the site’s secrets.

Out for a beer at the dawn of agriculture

Ever since the so called Braidwood Symposium in 1953 (Braidwood et al. 1953), there has been a debate as to whether beer – and not bread – was the first product made from domesticated crops (e.g. Katz and Voigt 1986). Based on the discovery of grain at the site of Qalat Jarmo, and at the suggestion of the archaeo-botanist Sauer, Braidwood inquired whether or not the discovery of fermentation could have been the spark that triggered the targeted selection, and ultimately domestication, of certain crops. Fermented grain, which sees its starch transformed into sugars, is well known for its beneficial properties, including an increase in nutritional value, also making it easier to digest. Indeed, the participants at the aforementioned symposium eventually came to the consensus that early grain crops would have been far better suited to the production of gruel or beer than bread, especially considering that the glumes of primitive domesticated plants would have adhered to the grain. Even though this idea (fermentation) was raised frequently in subsequent years (Katz and Voigt 1986), particularly in the context of the previously noted advantages (higher nutritional value) afforded by this process, it was considered improbable that beer was actually produced. More recently, however, the discussion was revisited in a contibution by P. McGovern (2009) who presented preliminary results from chemical studies made on two stone vessels from the PPN necropolis at Körtik Tepe which yielded traces of tartaric acid that accrues during the wine production process (McGovern 2009: 81).

Recently, further chemical analyses were conducted by M. Zarnkow (Technical University of Munich, Weihenstephan) on six large limestone vessels from Göbekli Tepe. These (barrel/trough-shaped) vessels, with capacities of up to 160 litres, were found in-situ in PPNB contexts at the site. Already during excavations it was noted that some vessels carried grey-black adhesions. A first set of analyses made on these substances returned partly positive for calcium oxalate, which develops in the course of the soaking, mashing and fermenting of grain. Although these intriguing results are only preliminary, they provide initial indications for the brewing of beer at Göbekli Tepe, thus provoking renewed discussions relating to the production and consumption of alcoholic beverages at this early time. Further, they are particularly significant in light of results from genetic analyses, undertaken by a team from the Norwegian University of Life Sciences in Oslo, which have suggested that the earliest domestication of grain occurred in the vicinity of the Karacadağ, i.e. very near to Göbekli Tepe (Heun et al. 1997 [external link]). Once again, we must ask whether the production of alcohol and the domestication of grain are interrelated. Finally, the aforementioned insights also provoke new questions relating to the use and consumption of alcohol at Göbekli Tepe, which may have been in the context of religiously motivated feasts and celebrations. Not surprisingly, such events are well attested in the ethnographic literature as a means of attracting and motivating large groups of people to undertake communal work and projects (Dietler and Herbich 1995).
