This paper reviews the, so far available, paleorecords of Vitis sylvestris C.C. Gmel and Vitis vinifera L. from Romania. The study takes into consideration the presence of Vitis pollen from Holocene peat sediment sequences and archaeological context, but also the presence of macrorests from various archaeological sites that date from Neolithic, Chalcolithic, Bronze Age, and La Tène. Both paleobotanical arguments and archaeological discoveries support the theory that places the beggining of viticulture in Romania a few millenia ago, in Neolithic period. Also, written evidences (works of classical authors, epigraphical sources) confirm, indirectly, the presence of grapevine in La Tène period. Occurrences of Vitis vinifera and those of Vitis sylvestris manifest independently of the climate oscillations, being present both through colder and more humid episodes, as well as through drier and warmer events. Probably prehistoric communities have made a constant and deliberate effort, all along the Holocene, to maintain grapevine crops.

The paper analyzes the archaeobotanical and archaeozoological remains originating from the middle Holocene (i.e. Chalcolithic site of Poduri- Dealul Ghindaru, in Eastern Romania, Bacău County). Poduri- Dealul Ghindaru site is the only tell settlement known in the area of existence of the Cucuteni culture, with inhabitation levels from Neolithic to the Bronze Age. In order to better understand the diet components of the prehistoric inhabitation belonging to the Cucuteni A and Cucuteni B phases, we follow evidence from archaeozoology, carpology, and palynology. For the carpological taxa, we calculate their ubiquity, diversity, and edibility score. The two sets of taxa are then compared in their similarity. Palynological data record the presence of cereal grains in all samples. We present the archaeozoological taxa with their quantification values and we calculate for the Cucuteni A and B phases, and in comparison with the Bronze Age sample, their richness, Shannon–Weaver diversity index and equitability. A correspondence analysis is carried out in order to compare the exploitation strategies for the three assemblages. For the archaeobotanical data, we find that the Cucuteni A phase is dominated by anthropogenic activity indicators and a heavy reliance on cereals. The Cucuteni B phase seems to be characterized by a restriction of human activity. The archaeozoological data highlight a preference for large mammals (cattle, dear, boar) during Cucuteni A and BA and smaller mammals during Cucuteni B (sheep/goat, pig, hare). We conclude that although the subsistence strategies remain similar, the dietary components change during the Cucuteni A and B phases, probably in response to environmental changes.

The commercial acrylic copolymer Paraloid B72 (PB72) and a synthesized nanostructured material (AMF) bearing silsesquioxane, methacrylate and fluorine units were analyzed to assess their performances as protective coatings for the conservation of Neolithic Cucuteni ceramic pottery when submitted to UV ageing. In the context of comparative evaluation of the protective efficiency, the present paper reports the use of a functional coating that operates via specific photochemical transformations at the coating-air interface as a UV resistant protection coating for cultural heritage artefacts. The main factors that influenced the photo-degradation behavior of the polymeric materials included their structure, the properties at the polymer/air interfaces, and the preferential orientation of functional groups at the surface of the polymeric coatings.
