Morphometric distinction between bilobate phytoliths from <Emphasis Type="Italic">Panicum miliaceum</Emphasis> and <Emphasis Type="Italic">Setaria italica</Emphasis> leaves

The development of identification criteria for crop plants based on phytoliths is of high relevance for archaeology, palaeoecology and plant systematics. While identification criteria are available for major food crops, these are mostly based on phytoliths from inflorescences, while other plant parts remain undetected. This paper focuses on bilobate phytoliths from leaves of Panicum miliaceum L. (common millet) and Setaria italica (L.) P. Beauv. (foxtail millet), two taxa that co-occur in regions of Asia and Europe since prehistory and regularly occur at archaeological sites in Eurasia. Leaves of the investigated taxa were systematically sampled to explore the variation of short cells and to collect 27 morphometric variables of bilobate phytoliths with newly developed open-source software. The data was analysed by discriminant analysis, analysis of variance and multiple comparison tests. The resulting morphometric data from five populations per species enables a distinction between the bilobate phytoliths of P. miliaceum and S. italica. Observed differences between populations within species affect only few parameters. This possibility to classify populations of bilobate phytoliths from P. miliaceum and S. italica leaves offers a new method for the detection and identification of these taxa in archaeology, amongst others.     

FTIR imaging and HPLC reveal ancient painting and dyeing techniques of molluskan purple

Fourier transform infrared spectroscopy and imaging coupled to optical microscopy, scanning electron microscopy coupled to energy dispersive x-ray spectroscopy and high-performance liquid chromatography (HPLC) coupled to diode-array detection are used to investigate two samples removed from a painted decoration of a burial kline and a textile fragment, both found in Koru tumulus (fifth century BCE) in Daskyleion. Tyrian purple and kaolinite were identified in both samples, thus suggesting that the aluminosilicate compound had an important role in the applied painting and dyeing processes. The textile fragment is composed of undyed cotton and silk yarns dyed with the molluskan dye. The relative compositions of the molluskan materials used in the two archaeological objects are similar and comparable with the corresponding composition measured for a purple sample originated from Murex trunculus mollusks according to the HPLC results. This result is supported by principal component analysis (PCA) which, furthermore, takes into account the relative compositions of the extracts of the three Mediterranean mollusks, published in previous reports.     

Remarks on Early Iron Age Burial Sites from Southern Cameroon

For the first time, graves dating to the Early Iron Age between 2000 BP and 1700 BP have been discovered in the southern Cameroonian rain forest. The features in question, from the sites of Akonétye and Campo, were almost identically furnished with iron objects and ceramic pots. Other features with more or less corresponding finds have been discovered at Mouanko–Lobethal, Mouanko–Epolo, Kribi–Mpoengu, and Yaoundé–Obobogo. The spatial distribution of these sites and their near synchronous dating suggest that a particular burial rite was practiced over a considerable area of southern Cameroon during the Early Iron Age.     

State Formation in Southern Africa: A Reply to Kim and Kusimba

Kim and Kusimba misunderstand the archaeological data pertaining to K2, Mapungubwe and Great Zimbabwe because they rely on secondary sources. Before these capitals can be categorized according to definitions of early states elsewhere, they need to be interpreted in their own terms. Ultimately, Mapungubwe and Great Zimbabwe are no less complex because they differ from early states in Asia or Middle America.     

The Hammers of Mawu: Ironworking Traditions in the Togo Hills,Ghana

This paper examines ironworking practices and traditions among the Mawu (Akpafu) and Lolobi communities of the northern Volta Region of Ghana. It compares them with other accounts gathered from published sources and observations made during fieldwork conducted in the 1970s. It describes the processes of mining, smelting, and tool manufacturing from reconstructions and oral histories and delineates the transformations that have been worked on the content of the tradition in the past 100 years. The narratives of the migrations of the Mawu, gleaned from their own elders, from ground surface evidence, and from written reports are considered in the context of archaeological and historical evidence from other parts of southern Ghana. The conventional picture of the movement of the Mawu/Lolobi communities is one of displacement by incoming groups, but the conclusion that they have been pushed within the past 150 years into the very district containing the greatest concentration of iron-rich deposits in this whole mountain area is given critical examination. It is likely that the Togo hills have been the site of ironworking for several centuries. It is, therefore, suggested that these communities may represent the distillation of a formerly more widespread set of such communities which existed wherever iron ore was to be found in southeast Ghana.
