LOCAL ROMAN COARSE WARES FROM CHHIM (SOUTHERN LEBANON)

Archaeological work have been undertaken since 1996 by a Polish mission. This paper aims to present the ceramic material dated on Roman time. Excavations have mainly focused on the rooms in the village and area around Roman Temple and Byzantine basilica. The largest collection of coarse ware comes from sectors containing an oil press and from two cisterns. Pottery from the mountainous regions of southern Lebanon is an entirely unknown entity. The ceramic assemblage from this site provides an excellent introduction to typological and comparative studies and many also point to links with territories influenced by southern regions.

Calcined and sintered nanopowders were characterized by FT-IR, XRD, BET, SEM, and AFM techniques. According to the XRD analysis, the obtained powders are single phase and independent of the dopant concentration in the range investigated. The crystallite sizes were calculated using Scherrer equation. Moreover, lattice parameters, dislocation densities and microstrain values were calculated. BET results show that the increase of the neodymium doped content decrease the surface area of the composite powders, confirming the highly ordered micro and mesostructure. SEM and AFM results show that the samples have spherical grains. According to the surface roughness measurements, the increase in the amount of neodymium and the decrease in the amount of cerium decreased the surface roughness.

The powders were characterized during the various steps by structural and morphological techniques (FT-IR, XRD, and SEM). XRD results proved that a tetragonal phase is predominant for all samples with varying magnesium contents and no monoclinic zirconia solid solution appears. The crystallite sizes of the samples were calculated using Scherrer equation. The smallest crystallite size was obtained for the sample containing Zr/Mg/Ce/Gd/B ratio of 82/0/10/8/0. The lattice parameters were calculated for cubic, tetragonal, hexagonal, and orthorhombic structures. SEM results show all the samples have spherical grains. The average grain diameters were calculated for all the samples. The smallest average grain diameter was obtained for the sample containing Zr/Mg/Ce/Gd/B ratio of 82/0/10/8/0.

The author's new project examines the context of Timbuktu's prehistoric urbanism by mapping the settlement patterns in its hinterland, and seeks to understand the social impacts of the Sahara's changing climate.

This research explores human response to climate change and asks how this interaction may have helped to form the large-scale prehistoric urbanism in the Timbuktu region. New understandings on the nature of prehistoric urbanism on the Niger Bend have been laid out by employing various theories and working models that deal with the social relationship with the changing climate and seasonal environment. The archaeological data used to address these theories and models were obtained over three seasons of research between 2008 and 2010. Field research involved intensive excavation and survey at the Iron Age tell complex of Tombouze (9 kilometers southeast of modern Timbuktu). Additionally, a wide ranging reconnaissance of the larger Timbuktu region and various forms of paleo-climate studies were also undertaken.
My findings suggest that the roles of changing climate regimes, a highly variable seasonal environment, and the unique ways local populations interacted with a difficult and marginal landscape, were all important in the formation of a dense and expansive prehistoric urban landscape. Incipient and small-scale semi-sedentary groups which came to the Timbuktu region at approximately 500 BC gave rise to a fully permanent yet highly flexible form of urbanism circa AD 650. Abandonment of the large urban centers and their hinterlands occurred at approximately AD 1000, soon before the foundation of historic Timbuktu by the Tuareg.
Investigation and analysis into the unique character of the prehistoric settlements of the Timbuktu region has produced a new hypothetical model of urbanism which may have application to the rest of the Niger Bend region. Known as the "Tombouze Model", this hypothetical construct suggests that urbanism fluctuates on a seasonal basis in accordance with the high and low flood seasons. During the high flood season, when dry land is limited, the prehistoric urban populations coalesced onto numerous large focus tells reaching probable dimensions of up to 100 hectares. During the low flood season, when land is plentiful but water scarce, the prehistoric populations radiated out into the hinterlands of the focus tells establishing temporary yet specialized seasonal camps in the floodplains while a much reduced permanently inhabited settlement core remained at the focus tells.
Throwing Small Vessels in the LM IB Mochlos Potter's Pit

Through experimentation we reconstructed how a Minoan potter at Mochlos would have produced cups, bowls, small jars, and jugs. Understanding how potters organized themselves to produce pottery is one insight into how Minoan craftsmen and craftswomen thought about their environment and their trade. Experimental archaeology and anthropological theory in Bronze Age studies are central to the reconstruction of all aspects of human activity. The study of the cultural process of human activity is a field of research that has the ability to breathe life into the archaeological record, for it brings the dynamic to the static.

Introductory Paragraph:
The aim of anthropology and archaeology is to explain and explain the physical and cultural characteristics of humankind's entire existence across space and through time. Experimental research creates a dynamic physical analogy that allows the archaeologist to develop plausible interpretations of changes in cultural process by linking the types of artifacts they collect in the field with specific human activities. In other words, experimentation gives aspect to the static archaeological assemblage, allowing the archaeologist to understand the interactive relationships between artifact and person in the past. Being able to ascertain changes in the cultural process, along with having an appreciation for environmental conditions, allows for an understanding of how cultural and personal agencies interact with the adoption and adaptation of internal and external cultural influences.

The black pigment contains pyrolusite and jacobsite; quartz and anatase have only accidentally been observed. Black Carbon was also identified, but only in two samples. The spherical or oblate black corpuscles discovered at Feteşti-La Schit (Suceava county) were analyzed by means of X-ray diffractometry and Raman spectroscopy. They consist of Mn ± Fe oxihydroxides and quartz. No Mn carbonates or silicates have been identified. The mineralogical composition of the pigment applied to the pottery shards, as well as that of the raw pigment, together with the use of the same pigment over a long period of time (1100 years), suggest the exploitation of a large.

Sites 1 and 2 produced evidence of both ritual and domestic activity, including the deliberate deposition of unworked stones during the Early Neolithic period. A second phase of occupation occurred during the Late Bronze Age. A similar preoccupation with the deliberate burial of stones was noted at Site 3, though dated to the end of the Late Neolithic and into the beginning of the Early Bronze Age. Site 5 revealed extensive remains from the Early Neolithic and appeared to be formally divided into areas of domestic activity and ritual deposition. The domestic area was centred on a number of metalled surfaces around a large trough-like feature, while the ritual area was composed of a low hollow with a metalled base and a vertically set stone, surrounded by a low bank. Significant quantities of flint and pottery were deposited in this area.
