Grain versus chaff: identifying a contrast between grain-rich and chaff-rich sites in the Neolithic of northern Greece

Recent archaeobotanical investigations of Late Neolithic sites in northern Greece have revealed a pattern as regards the crop parts represented at each site. Some sites appear to be dominated by chaff, mainly glume wheat chaff, while other sites are mainly characterised by cereal grain and pulses. This pattern could be the outcome of various factors: a. pre-depositional differential treatment of crops selecting for one category of plant remains to arrive at the site, b. depositional, therefore related to the type of activity represented at the excavated contexts and the use of space in relation to plants, and c. post-depositional factors such as erosion, or the type of features sampled. These alternative factors are considered in light of the preliminary results of the archaeobotanical investigation of seven Late Neolithic (5500–4000 cal. B.C.) sites from northern Greece. It is suggested that this pattern is the outcome of a differential use of space in relation to plants (storage, processing/food preparation, refuse disposal), probably related to aspects of the socioeconomic organisation of the settlements.     

Evidence for Mesolithic agriculture in and around central Europe?

A critical assessment of the data recently put forward in favour of a ‘Mesolithic agriculture’ for Central and Northern Europe is presented. The archaeobotanical record is quite clear: hundreds of excavations of early Neolithic sites, whether from Linearbandkeramik or Trichterbecher (funnel beaker) settlements have produced remains of cultivated plants in large numbers. In contrast to this, all Mesolithic sites excavated so far have not revealed even one macroscopic find of crop plants. The ‘Mesolithic agriculture’ as assumed by several authors, is based solely on single pre-Neolithic pollen grains of the Cerealia-type that occur in pollen diagrams. It is shown that absolute distinction of pollen from wild grasses and cereals is impossible. There is a certain overlapping of both types that must not be neglected. Because of the large pollen sums in modern pollen diagrams, even very scarce grains of Cerealia-type pollen are encountered. Most of these single pre-Neolithic grains must derive from native wild grasses, while others come by long-distance transport etc. Another important feature is the scattered occurrence of Cerealia-type pollen grains from the early Holocene (or even Pleistocene) to the start of the Neolithic. They do not occur in synchronous phases and even in neighbouring sites they do not agree in age. As long as there are no well-dated macro-remains of crop plants of pre-Neolithic age, there is no evidence of Mesolithic agriculture.     

Late Neolithic agriculture in eastern Austria: archaeobotanical results from sites of the Baden and Jevišovice cultures (3600–2800 b.c.)

The article presents archaeobotanical results from six late Neolithic excavation sites in eastern Austria. Two of the sites belong to the Jevišovice culture (3200–2800 cal b.c.), the remaining four to the Baden culture (3600–2900 cal b.c.). Results show that farmers around 3000 cal b.c. were relying on the use of Triticum monococcum and Hordeum vulgare as principal cereals, with Triticum dicoccum and Panicum miliaceum as additional crops. Common millet was found in quantity at one of the Jevišovice sites and shows the remarkably early westward spread of this species. Single records of Triticum spelta are discussed in the light of the recently proposed ideas about an independent central European origin of spelt. Another record concerns the “new-type” glume wheat, providing further evidence for the once widespread occurrence of this cultivar. Triticum aestivum (hexaploid naked wheat) and Setaria italica (foxtail millet) were found as rare admixtures at the Jevišovice settlements. Pulses were represented by Pisum sativum and Lens culinaris, oil plants by Papaver somniferum and Linum usitatissimum. One of the Jevišovice sites offered a good opportunity for a study of the undisturbed spatial distribution of charred plant remains within a burnt house. Among wild plants, the occurrence of Stipa sp., Teucrium chamaedrys, Asperula cynanchica and Plantago media point to the presence of dry steppe grassland in the vicinity of the settlements, which was probably used for grazing. Woodland plants were mainly represented by fruit-bearing plants growing in clearings and forest edges, reflecting both the deliberate collection of wild fruits and the growing human impact on the vegetation.     

Water management practices and climate in ancient agriculture: inferences from the stable isotope composition of archaeobotanical remains

Carbon isotope discrimination (Δ¹³C) in charred grains from archaeological sites provides reliable information about water availability of ancient crops. However, as cereals are cultivated plants, they may reflect not only climatic fluctuations, but also the effect on water status of certain agronomic practices, such as sowing in naturally wet soils or irrigation. In this work, we propose a methodological approach to combine Δ¹³C data from different plant species, in order to discriminate between climate-derived and anthropogenic effects on ancient crops. We updated previous models for estimating water inputs from Δ¹³C of cereal grains of Hordeum vulgare and Triticum aestivum/durum, and we applied them to published data from several archaeological sites, including samples from the Neolithic to the present day in northeast and southeast Spain, as well as from the Neolithic site of Tell Halula (northwest Syria). We found an important decrease in water availability from the Neolithic to the present time in the three areas of study, especially clear for the two driest areas (southeast Spain and northwest Syria). Potential differences in water management practices between wheat and barley, as well as between cereal and legume crops (Vicia faba and Lens culinaris), are also discussed on the basis of the comparison of Δ¹³C values across several archaeological sites.     

Crop growing and gathering in the northern German Neolithic: a review supplemented by new results

New archaeobotanical results from 15 Neolithic sites in northern Germany are presented in a review of the Neolithic plant economy in northern and north-western Europe. Available archaeobotanical data from north-western Europe are evaluated and compared with our new results. In the whole region, barley and emmer were the main crops. Regional and diachronic differences are observed in the cultivation of einkorn, spelt and naked wheat. For oil plants and pulses only rare information from macro remains is available, as we mainly deal with charred material. It is noticeable that gathered plants played an important role in the Funnel Beaker economy. Plant choice, especially the relevance of cultivated versus gathered plants is discussed, based on new and existing data. Based on a structural comparison of charred plant assemblages from domestic sites and tombs, we develop a research hypothesis that settlement finds provide insight into production and consumption of food from crops, while tombs mainly yield evidence of plants gathered in the wild or in semi-wild areas in the vicinity of former settlements. Therefore, we suggest a model of different purposes and meanings of plants, depending on whether primarily an economic or a social/ritual sphere is regarded. But, for all evaluations and interpretations, it is essential to consider the taphonomic processes and conditions. Therefore, further research is necessary to verify our hypothesis, which derives from first insights into new material.     

The Early Neolithic site at Hoge Vaart, Almere, the Netherlands, with particular reference to non-diffusion of crop plants, and the significance of site function and sample location

The construction of a new motorway necessitated the excavation of an Early Neolithic site in the Dutch Flevopolder near the Hoge Vaart canal. In 1994-1996, an area of ca. 1700 m² was excavated in 0.5x0.5-m squares. The excavation revealed 150 surface hearths and more than a hundred deep hearth pits. The finds, mainly flint and pottery, as well as¹⁴C dates from charcoal demonstrated that the area had been used mainly during the Early Neolithic (ca. 4900–4500 cal. B.C.). The investigation of the Early Neolithic remains included detailed botanical analyses of 182 samples and hand-sorting by the excavation team, which included archaeobotanists, of tens of thousands of samples sieved over 2-mm-mesh sieves. No remains of cultivated plants were recognised among the 87 taxa (40 identified to species level) that were preserved, mainly in carbonised form. These results are compared with other Early Neolithic sites studied in the Netherlands, such as Swifterbant S3 and Schokland P14. The possible significance of site function and sample location as important factors influencing presence/absence of cultivated plant remains at a particular site is discussed.     

Continuity and changes in plant resources during the Neolithic period in western Switzerland

The Neolithic and Bronze Age (4400-1570 B.C.) pile dwellings of Concise-sous-Colachoz on the shore of Lake Neuchatel (Canton of Vaud, western Switzerland), known as an archaeological site for more than 140 years, were recently re-investigated due to rescue excavations. Plant macrofossil analyses were done for several Neolithic occupation phases (3868-2440 B.C. the Cortaillod classique, Cortaillod moyen, Cortaillod tardif and Auvernier periods) with a focus on cereal remains, and additionally, archaeological deposits dating to the Cortaillod moyen culture (3710-3677 B.C.) were studied in detail. The preliminary study of cereal macrofossil remains from all the mentioned Neolithic phases show that the most important cereals were Triticum aestivum/durum/turgidum (naked wheat), T. monococcum (einkorn) and Hordeum vulgare (barley). The preferences for specific crops did obviously not alter significantly through time, but, extraordinarily, significant amounts of einkorn continued to be grown for at least 1400 years during the Neolithic period. Other cultivated plants were Pisum sativum (pea), Linum usitatissimum (flax), and Papaver somniferum (opium poppy). Additionally to the seeds, capsule fragments of opium poppy were found in the Cortaillod moyen deposits. These represent the first finds of uncharred capsule fragments in Europe. Compared with other central European sites, opium poppy was very common during the 38th and 37th cent. B.C. and obviously less appreciated towards the end of the Neolithic in the western part of Switzerland. In central Switzerland the trends seem different: there opium poppy was mainly used during the Late Neolithic period. This may be due to cultural differences within contemporaneous human societies. Wild fruits which were collected as plant resources during the Cortaillod moyen period included Prunus spinosa (sloe), Cornus sanguinea (dogwood), Malus sylvestris (apple), Rubus idaeus/caesius/fruticosus (raspberry/dewberry/blackberry), Fragaria vesca (wild strawberry), Rosa sp. (hip), Quercus sp. (acorn), Corylus avellana (hazelnut), and Fagus sylvatica (beechnut), among others. Compared with other Neolithic sites in westem and central Switzerland the local population of Concise-sous-Colachoz used few sloes, while dogwood fruits were in use throughout the Neolithic period at Lake Neuchatel.

Morphological studies of free-threshing wheat ears from a Neolithic site in southwest Germany, and the history of the naked wheats

Two hundred and seventy carbonized naked wheat ears from the Neolithic pile dwelling at Hornstaad-Hörnle IA/Lake Constance (Germany) were analysed. The characteristics of internodes and glumes show that only tetraploid naked wheat types were cultivated. Following the history of free-threshing wheats it seems conceivable that the tetraploid naked wheats spread from their point of origin in the Middle East (7th/8th millennium B.C.) via a Mediterranean route to southwest Europe, reaching the northern foothills of the Alps about 4000 B.C.     

Archaeobotanical analysis of some early Neolithic settlements in the Kujawy region, central Poland, with potential plant gathering activities emphasised

Neolithic settlements in the Kujawy region of central Poland are represented by seven archaeological sites which have botanical material archaeologically dated to the Linear Pottery culture (LBK) (ca. 5400-5000 cal. B.C.) and the Lengyel culture (ca. 4400-4000 cal. B.C.). The composition of plant remains suggests that Stipa pennata s.l. played a certain role in the economy of the Neolithic settlers. The presence of this xerothermic grass is best explained by local gathering rather than distant transport or coming into the sediment by chance. The finding of Hierochlo? cf. australis grains represents the first identification of this plant in archaeobotanical material from Poland. This, now rare, plant contains coumarin and for this reason could have been useful in prehistory. Other plants such as Bromus spp., Chenopodium album type, Fallopia convolvulus and Galium spp. were found in large quantities, and although common weeds now, they could also have been collected by the Neolithic settlers. Plants such as Corylus avellana and Vaccinium vitis-idaea that are typically considered to be collected as foods are present in the studied material but in very small quantities.

Prehistory of plant growing and collecting in northern Italy, based on seed remains from the early Neolithic to the Chalcolithic (c. 5600–2100 cal b.c.)

The stages of the early Neolithic and the spread of agriculture in northern Italy are difficult to determine and basically still unclear, since this region was influenced by deeply different cultures coming from both the Mediterranean coasts and the Balkans. The complex interrelations due to the contributions from both cultures are reinterpreted here thanks to recent data, modifying a picture which 15 years ago was believed to be definite. According to radiocarbon chronology, the appearance of the earliest farming communities in northern Italy should be dated around 5600–5500 cal b.c. Early farmers cultivated several cereal and pulse taxa, of which the more important were Hordeum vulgare/distichum, Triticum dicoccum, T. monococcum, T. aestivum/durum/turgidum, Lens culinaris and Pisum sp. In addition they gathered many wild plants. The spread of agriculture was a rapid phenomenon and within a few centuries agriculture was established into the Alps. Little is known about the middle and late Neolithic, with the Square-mouthed pottery culture “Bocca Quadrata”, from c. 5100 cal b.c. onwards, since most of the archaeological features discovered up to the present have produced only a few plant remains. We demonstrate the introduction of poppy and a few other innovations like a slightly increased cultivation of free-threshing cereals and flax. Archaeobotanical analyses from Chalcolithic or Copper Age settlements, from c. 3500 cal b.c. onwards, are even scarcer and a comparison with the earlier Neolithic settlements does not yet seem possible.     

Human impact as registered in the pollen record: some results from the western Lake Constance region,Southern Germany

Pollen analytical results from a littoral profile taken in Lake Constance compared with pollen profiles from small kettle holes nearby form the basis for conclusions concerning human population density, the economy and environment from the Neolithic period to the Middle Ages. Early Neolithic human impact is implicated in a lime decline and also the expansion of beech. The late Neolithic lakeshore settlements caused a decline of elm, beech and lime and, by shifting cultivation, considerably changed the forest cover. The settlements were abandoned after less than 100 years. There were long periods without distinct human impact in the middle and towards the end of the late Neolithic period. Since at least the Late Bronze Age there has been permanent habitation in the region. Human impact was greatest in the High Medieval period and later, and was also substantial in the late La Tène and Roman periods. Distinct declines in human impact can be observed between the La Tène and Roman periods and in the Migration and Merovingian periods. In these intervals, open land and grazed oak forest were replaced by birch and later on by beech forests. The decreases in human impact are not of the same intensity in all diagrams.     

Agricultural activities and land use in a Neolithic village around 3900 B.C.: Hornstaad Hörnle I A, Lake Constance, Germany

The archaeobotanical investigations in the Neolithic pile settlement of Hornstaad Hörnle I A, Lake Constance, Germany (3919–3905 cal B.C.) has answered many questions concerning agricultural activities and land use in Neolithic times. Very large carbonized stores of unthreshed cereals there showed that every household had 210–280 kg of naked wheat, einkorn, barley and emmer. As most of the wild plant remains in the cereal stores were from annual field weeds it is concluded that the arable land was cultivated continuously, probably for the whole duration of the settlement's occupation. No hints of short or long period fallows were found. Intensive soil treatment such as hoeing and digging is indicated by the rarity of perennial weeds. Because of the high quality of the cultivated soils, manuring was not necessary. The cereals were harvested high on the culm, and the harvest was first stored unthreshed, probably to dry it completely. Every house (family) had its own cereal stores with various cereals. Naked wheat and probably naked barley were threshed outside the settlement, while dehusking of einkorn and probably of emmer took place inside the village. Evidence of cereal cleaning, winnowing, sieving and sorting by hand were found. More than 700 carbonized remains of food products showed that porridge made from ground and shredded wheat was one of the main foods in the settlement.     

Early Neolithic agriculture in Ambrona, Provincia Soria, central Spain

The early Neolithic sites of La Lámpara and La Revilla del Campo in the Meseta Norte (Northern Meseta) plateau in central Spain produced evidence for early agriculture from the last third of the 6th millennium B.C. The hulled wheats Triticum monococcum (einkorn) and T. dicoccum (emmer) were identified from carbonised plant remains as well as from imprints in pottery and daub. Single finds of charred remains of Hordeum vulgare (barley), Papaver somniferum/setigerum (poppy) and Linum usitatissimum (linseed) indicated other cultivated crops. The wild plants mainly indicated arable weeds, partly from less fertile soils, and garrigue vegetation from poor pastures. The spectrum of crops from the Ambrona sites was compared to other inner Iberian sites as well as to Mediterranean sites. Sediment samples as well as mineral crusts from graves were analysed from the Neolithic tumulus of La Peña de la Abuela. Its diachronic collective burials had originated from a period of time during the first third of the 4th millennium B.C. Probably no crops, but many green vegetative parts of pine, oak, and juniper had been used as funeral gifts. Oak cupula development indicated early summer activities in the grave-mound. Wickerwork made of willow was used for embedding the dead bodies.     

New archaeobotanical finds of Isatis tinctoria L. (woad) from Iron Age Gaul and a discussion of the importance of woad in ancient time

Although chemical analyses of textile remains have traced the use of Isatis tinctoria L. (woad) back to the Neolithic period, archaeobotanical remains of the plant are scarce in north-western Europe, especially in France. A new discovery in the rural settlement of Roissy, north of Paris, raises the question of local cultivation of woad from at least the fifth–fourth century b.c. (La Tène A/B1) in northern Gaul. The plant assemblage comes from the filling of a storage pit, which also included a wide variety of cultivated plants. These data represent a valuable contribution to the study of the circumstances of the adoption of woad as a new crop.     

Changes in carbon isotope discrimination in grain cereals from different regions of the western Mediterranean Basin during the past seven millennia. Palaeoenvironmental evidence of a differential change in aridity during the late Holocene

Carbon isotope discrimination (Δ) was determined for kernels of six-row barley and durum wheat cultivated in the western Mediterranean basin during the last seven millennia. Samples came from different archaeological sites in Catalonia (north-east Spain) and in the south-east of Spain (mainly eastern Andalusia). Samples from the present were also analysed. Mean values of Δ for barley and durum wheat grains decreased slightly from Neolithic (7000–5000 BP) to Chalcolithic-Bronze (5000–3000 BP) and Iron ages (3000–2200 BP) both in Catalonia and in south-east (SE) Spain. Values were consistently lower in SE Spain than in Catalonia throughout these five millennia, which suggests that Catalonia was less arid than SE Spain in this period. Within a given region, current discrimination values for kernels of the same cereal species cultivated under rainfed conditions were lower than those of archaeological grains, which implies more arid conditions at present. Furthermore, an empirical relationship between Δ of mature kernels and total precipitation (plus irrigation where applicable) during grain filling (r² = 0.73, N = 25) was established for barley, currently cultivated at different locations in the western Mediterranean basin in Spain. The resulting relationship was applied to the Δ data for barley kernels from 10 archaeological sites in Catalonia and 10 sites in SE Spain, to estimate the precipitation during grain filling at the time the kernels were produced. For both regions, current climatic conditions are consistently more arid than those inferred for the Neolithic, Bronze and Iron ages. In addition, although Catalonia was estimated to have had consistently wetter conditions (about 20% more precipitation) than SE Spain throughout these millennia, differences in precipitation between these two regions have recently increased, with 79% more precipitation in Catalonia. Results indicate a more rapid increase in aridity in SE Spain than in Catalonia, probably produced during the last few centuries, and due to anthropogenic causes.     

Plant economy and village life in Neolithic lake dwellings at the time of the Alpine Iceman

This paper gives an overview of domesticated and wild plants used during the second half of the fourth millennium cal b.c. in a region within a semicircle of ca. 100 km radius around the find site of the Iceman. The landscape considered lies north of the main Alpine chain and includes central to eastern Switzerland and southwest Germany, mainly sites at the lakes Zug, Zürich, Constance (Bodensee), the Federsee region of Upper Swabia (Oberschwaben) and western Bavaria. From this part of central Europe, the plant remains of many well-preserved lake dwelling sites have been investigated during the last decades and much is known about daily life in these villages. Probably contemporary with the Iceman’s lifetime is one of the best-investigated settlements, Arbon Bleiche 3 on the southern shore of Lake Constance. A comparison of the Iceman’s artefacts and plant macro remains with the finds from the lake dwellings which have been studied shows striking similarities, but also differences. The Iceman’s southern provenance can be corroborated by the domestic plants found with him. He used domestic as well as wild plants, very similar to those of his contemporaries in the lakeside villages. The detailed knowledge of the manifold activities in the lakeshore village of Arbon Bleiche 3 allows us to show a rather realistic picture of daily life at the time of the Iceman.     

Identifying prehistoric collected wild plants: A case study from late bronze age settlements in the french alps (Grésine, Bourget Lake, Savoie)

The late Bronze Age lakeshore settlements of Grésine (French Alps) have yielded archaeobotanical evidence of 14 cultivated and 153 wild plants. Some of the wild taxa may have been collected, but many are probably here by chance. Three criteria are used as evidence for human transport and manipulation of wild plant remains: number of items, fragmentation, and carbonization. Relations between these criteria and known ethnobotanical properties of the identified plants are statistically analyzed. Results display good evidence of the gathering of edible wild fruits and seeds. Other gathering practices are not documented. Edible fruits and seeds seem to have been gathered mainly from ruderal spring weed communities and, possibly, from forest clearances and hedge communities. Fragmentation appears to be less of a discriminating factor than number of plant remains and carbonization.     

From the field to the hearth: plant remains from Neolithic Croatia (ca. 6000–4000 cal <Emphasis Type="SmallCaps">bc</Emphasis>)

Until recently the recovery of plant remains in Croatia was rare, resulting in few studies addressing the nature of Neolithic crop cultivation. This paper presents new archaeobotanical data from eleven Neolithic settlements in coastal and continental Croatia. Within continental Croatia, three sites dating to the Star?evo culture (early/middle Neolithic; ca. 6000–5300 cal bc) and six to the Sopot culture (late Neolithic; ca. 5300–4000 cal bc) are examined along with two Hvar culture sites (late Neolithic; ca. 4800–4000 cal bc) located along the coast. Different settlement types are included in the study: open air sites, tells and cave sites. From the data collected the most common crops identified were einkorn, emmer, barley, lentil, pea and flax, as well as the fruits Cornus mas (Cornelian cherry) and Physalis alkekengi (Chinese lantern), which were particularly dominant in the Sopot culture settlements. By examining formation processes, sieved crop processing products and by-products were identified at six of the sites, suggesting that cereals were processed on a day-to-day basis at the household level. In contrast, the remains from the late Neolithic coastal cave site of Turska Pe? suggest two distinct formation processes. At the eastern side of the cave the plant remains suggest that episodes of dung burning occurred, possibly to clear the cave of excess waste during seasonal habitation of the cave by herders and livestock. Towards the back of the cave, cereal remains and higher charcoal densities may suggest an area used for food preparation or cooking.     

Studies on the vegetation history of Lake Varna region,northern Black Sea coastal area of Bulgaria

On the basis of pollen analytical investigations of two cores from Lake Varna and Lake Beloslav, the vegetation history of the Lake Varna region is traced back to the beginning of the 6th millennium B.C. A two-fold zoning system is used whereby the pollen diagrams are divided into pollen zones, based on tree migration patterns, and settlement periods. Pollen zone 1 is characterised by the absence of Carpinus betulus and Fagus sylvatica. The spread of hornbeam started at ca. 6500 B.C. (pollen zone 2) and beech at ca. 6200 B.C. (pollen zone 3), the latter being the last tree to spread into the region and considerably enrich the forests of the study area. Of the many pollen taxa representing plants that are favoured by open habitats and hence potentially indicative of human impact, only a few taxa are regarded as reliable indicators of human activity. These include above all Triticum-type, and also Secale and to a certain extent Plantago lanceolata, Rumex and Polygonum aviculare. The spatial pattern of settlements is somewhat different in the areas represented by the two profiles. At both sites the first period of settlement occurred during the 6th millennium B.C. (early Neolithic). After the Neolithic period, the main settlement periods of the Eneolithic and the Early and Middle Bronze Age are recorded. On the other hand, land-use history during the Greek and Roman periods is poorly recorded. Studies on the stratigraphy, diatoms and molluscs indicate that the sixth Black Sea transgression (6500–5800 B.C.), which reached –10 m, had considerable influence on the limnological environment.     

Assessing the potential for recovery of lakeshore vegetation: species richness of sediment propagule banks

To assess the potential and develop appropriate techniques for the recolonization of lakeshore vegetation at sites where it had been completely lost, a pilot project was launched at Lake Kasumigaura, Japan. We investigated the species composition and density of the soil seed banks (propagule banks) of lake sediments at nine sites (total area, 65,200 m²) where lake sediments were spread thinly (∼10 cm) on the surfaces of artificial littoral zones. These zones were constructed in front of concrete levees and had microtopographic variations. In total, 180 species, including six endangered or vulnerable species and 12 native submerged plants that had disappeared from the aboveground vegetation of the lake, were recorded during the first year of restoration. The distribution of each restored species at the sites suggested the importance of microtopographic variation for recolonizing species-rich lakeshore vegetation. Furthermore, the origin of the source sediment affected the species composition of the established vegetation.
