    During the years 2003¿2005, a comparative ethnobotanical field survey was conducted on remedies used in traditional animal healthcare in eight Mediterranean areas. The study sites were selected within the EU-funded RUBIA project, and were as follows: the upper Kelmend Province of Albania; the Capannori area in Eastern Tuscany and the Bagnocavallo area of Romagna, Italy; Cercle de Ouezanne, Morocco; Sierra de Aracena y Picos de Aroche Natural Park in the province of Huelva, Spain; the St. Catherine area of the Sinai Peninsula, Egypt; Eastern and Western Crete, Greece; the Paphos and Larnaca areas of Cyprus; and the Mitidja area of Algeria. One hundred and thirty-six veterinary preparations and 110 plant taxa were recorded in the survey, with Asteraceae and Lamiaceae being the most quoted botanical families. For certain plant species the survey uncovered veterinary phytotherapeutical indications that were very uncommon, and to our knowledge never recorded before. These include Anabasis articulata (Chenopodiaceae), Cardopatium corymbosum (Asteraceae), Lilium martagon (Liliaceae), Dorycnium rectum (Fabaceae), Oenanthe pimpinelloides (Apiaceae), Origanum floribundum (Lamiaceae), Tuberaria lignosa (Cistaceae), and Dittrichia graveolens (Asteraceae). These phytotherapeutical indications are briefly discussed in this report, taking into account modern phytopharmacology and phytochemistry. The percentage of overall botanical veterinary taxa recorded in all the study areas was extremely low (8%), however when all taxa belonging to the same botanical genus are considered, this portion increases to 17%. Nevertheless, very few plant uses were found to be part of a presumed "Mediterranean" cultural heritage in veterinary practices, which raises critical questions about the concept of Mediterraneanism in ethnobotany and suggests that further discussion is required. Nearly the half of the recorded veterinary plant uses for mammals uncovered in this survey have also been recorded in the same areas in human folk medicine, suggesting a strong link between human and veterinary medical practices, and perhaps also suggesting the adaptive origins of a few medical practices. Since most of the recorded data concern remedies for treating cattle, sheep, goats, and camels, it would be interesting to test a few of the recorded phytotherapeuticals in the future, to see if they are indeed able to improve animal healthcare in breeding environments, or to raise the quality of dairy and meat products in the absence of classical, industrial, veterinary pharmaceuticals

    Millets across Eurasia: chronology and context of early records of the genera Panicum and Setaria from archaeological sites in the Old World

    We have collated and reviewed published records of the genera Panicum and Setaria (Poaceae), including the domesticated millets Panicum miliaceum L. (broomcorn millet) and Setaria italica (L.) P. Beauv. (foxtail millet) in pre-5000 cal b.c. sites across the Old World. Details of these sites, which span China, central-eastern Europe including the Caucasus, Iran, Syria and Egypt, are presented with associated calibrated radiocarbon dates. Forty-one sites have records of Panicum (P. miliaceum, P. cf. miliaceum, Panicum sp., Panicum type, P. capillare (?) and P. turgidum) and 33 of Setaria (S. italica, S. viridis, S. viridis/verticillata, Setaria sp., Setaria type). We identify problems of taphonomy, identification criteria and reporting, and inference of domesticated/wild and crop/weed status of finds. Both broomcorn and foxtail millet occur in northern China prior to 5000 cal b.c.; P. miliaceum occurs contemporaneously in Europe, but its significance is unclear. Further work is needed to resolve the above issues before the status of these taxa in this period can be fully evaluated

    Environmental change in Crete:a 9000-year record of Holocene vegetation history and the effect of the Santorini eruption

    Palynological investigations were carried out in the coastal lowland of northwestern Crete, in the area of Lake Kournas. Results comprise the longest continuous vegetation record ( 9000 radiocarbon years) for Crete. From about 8500 to 7500 BP, open deciduous-oak forest occurred and appears to reflect the driest conditions of the Holocene. After 7500 BP, tree-pollen numbers increase. Some of these tree species are thought to be autochthonous, but for at least six species this is doubted and the presence of their pollen is ascribed to long-distance transport. Up to 6000 BP, the local vegetation included deciduous and evergreen oaks, Pistacia, Phillyrea and a variety of herbs. Only after 7000 BP, some species, e. g., Mercurialis annua, Cynocrambe and spores of Pteridium, might indicate the effects of Neolithic habitation. Towards 6000 BP, plane tree and Styrax ( storax) appear; from about 6000 BP, olive is present and human activity becomes more evident. Slowly, pollen types indicative of the exploitation of present-day Mediterranean vegetation, e. g., Poterium and Ericaceae, appear and the presence of the alga Gloeotrichia indicates a rise in phosphate. A striking aspect of the sediment core nearest to the sea is a pumice layer originating from the Theran ( Santorini) eruption. From the manner of its deposition it is concluded that no tsunami met the Cretan beach. Influence of the eruption from Thera on the vegetation is hardly visible. Decrease of economically important cultivated plants, e. g., olive, already took place decades, up to about a century, before the volcanic eruption. Around the time of the eruption, the values of some pollen types hardly changed, others increased and another group decreased. This pollen behaviour appears to be explained rather by socio-economic changes, such as withdrawing of the inhabitants to the interior for reasons other than volcanic effects. It is concluded from the pollen cores that no major climatic changes affected northwestern Crete during the Holocene but the first two millennia of the Holocene tended to be drier than the following period when there was an increase in moisture-demanding trees. It is difficult to assign changes in the Cretan vegetation to climatic effects in a period when human impact was gathering strength

    Charred olive stones: experimental and archaeological evidence for recognizing olive processing residues used as fuel

    After extracting oil from olives a residue is left usually referred to as the olive oil processing residue (OPR). This study explores the way in which ancient societies may have used OPR as fuel for fires to generate heat and the various issues that are related to the residues of this fuel. After drying, the high heating value and structure of OPR makes it an excellent and efficient fuel. Upgrading OPR further, through thermal conversion or charring, provides an even more efficient fuel (COPR), with a hotter and smoke free flame, a higher heating value and which is lighter in mass and thus easier to transport. After a fire is extinguished two types of remains of the fuel are left i.e. char and ash. Analyses on both remains, recovered from archaeological deposits, could be used as a source of information on fuel utilization. Laboratory experiments on charred modern OPR and stones show that by measuring their reflectance and analyzing their structure under reflected light microscopy, OPR and COPR can be distinguished in the charred material recovered from three archaeological sites in Greece and Syria. Based on these investigations it is suggested that on the three sites COPR was used as fuel. Ash, sampled together with the char, provides the possibility of investigating if other types of fuel were used, apart from OPR or COPR. On the investigated sites no ash was collected, but the analysis of the modern OPR showed that the properties of its ash could be used to distinguish it from other types of fuel. Ash from modern OPR and olive stones showed the presence of phytoliths. The often discussed issue related to the sharpness and smoothness of the edges of charred fragmented olive stones was investigated. The results showed that this is not a reliable criterion for recognizing olive oil production. It is recommended that in addition to the identification of the botanical material more properties of the remains of fuels should be analysed. To prevent destroying and losing char and ash as a result of excavation activities such as flotation and sieving, special measures have to be taken. The results show that analysing char and ash may provide valuable information on the (pyro)technology practised in ancient societies
