La cultura talayótica una sociedad de la edad del hierro en la periferia de la colonización fenicia

Abstract: The Talayotic culture. An Iron Age society in the periphery of the phoenician colonization. The present study explains a critique about the chronological bases on which the origins of the Talayotic culture of the Balearic Islands have been grounded. From this, a new chronological framework is accepted, which has already been postulated by various research teams in recent years. The synchronicity that is seen between the Talayotic culture’s beginnings and its initial development, and the arrival of iron on the islands, as well as the substantial changes seen in the network of overseas trade in the Central and Western Mediterranean, which came to be monopolised by Phoenician merchants, permits us to suggest that the crystallisation and evolution of the Talayotic society, with its clear and well-known peculiarities, are also included within this geohistoric context. Indications of the Talayotic culture’s ultimate causes, however, point to endogenous origins and a period of prior gestation in the midst of Balearic communities of the Naviform Bronze Period. A sequence is also proposed for the models of trade among the agents that controlled long-distance maritime commerce, that is, among the Phoenicians, the Punic peoples of Ibiza afterwards, and the Talayotic communities of Majorca and Minorca. Not touched upon in the present paper are matters related to the typology and function of Cyclopean turriform architecture, nor those related to the material culture whose understanding has been re-assessed, up dated, and disseminated in the archaeological literature of recent years.

Making pots : el modelado de la cerámica a mano y su potencial interpretativo

Abstract: This book analyses the technological process of ceramic moulding. To this end, the work is organised into four sections: The first section discusses the concepts on which the analyses are based. The second section analyses the theoretical-methodological background. This section is based on a social view of the operational chain and on a specific design adapted to the technological interpretation of the macro-traces created by the ceramic moulding process. The third section discusses the entire protocol for the technological identification of macro-traces created by the ceramic moulding process. The final section deepens the interpretative strategies offered by the ceramic moulding analysis and the volume concludes with a reflection on the limits and possibilities of the proposed methodology.

Acción técnica, interacción social y práctica cotidiana: propuesta interpretativa de la tecnología

Abstract: This article is focused on the potential of technological analysis of material culture understood as an eminently social practice. This perspective allows us to incorporate all the information derived from the analysis of technical gestures with other concepts such as the technological know-how of the group, learning processes, socially constructed technological practices, etc. Thus, these concepts permit to establish methodological strategies from technological analysis that go beyond pure technical gestures. Furthermore, this procedure allows us to go into the set of daily social praxis that are developed in the production and use of objects which are significantly involved in the construction of the social arena of the communities. As a case study of this proposal we cited diferents examples of the handmade production of pottery.

The spread of steppe and Iranian-related ancestry in the islands of the western Mediterranean.

Abstract: Steppe-pastoralist-related ancestry reached Central Europe by at least 2500 bc, whereas Iranian farmer-related ancestry was present in Aegean Europe by at least 1900 bc. However, the spread of these ancestries into the western Mediterranean, where they have contributed to many populations that live today, remains poorly understood. Here, we generated genome-wide ancient-DNA data from the Balearic Islands, Sicily and Sardinia, increasing the number of individuals with reported data from 5 to 66. The oldest individual from the Balearic Islands (~2400 bc) carried ancestry from steppe pastoralists that probably derived from west-to-east migration from Iberia, although two later Balearic individuals had less ancestry from steppe pastoralists. In Sicily, steppe pastoralist ancestry arrived by ~2200 bc, in part from Iberia; Iranian-related ancestry arrived by the mid-second millennium bc, contemporary to its previously documented spread to the Aegean; and there was large-scale population replacement after the Bronze Age. In Sardinia, nearly all ancestry derived from the island’s early farmers until the first millennium bc, with the exception of an outlier from the third millennium bc, who had primarily North African ancestry and who—along with an approximately contemporary Iberian—documents widespread Africa-to-Europe gene flow in the Chalcolithic. Major immigration into Sardinia began in the first millennium bc and, at present, no more than 56–62% of Sardinian ancestry is from its first farmers. This value is lower than previous estimates, highlighting that Sardinia, similar to every other region in Europe, has been a stage for major movement and mixtures of people. The history of human populations in the islands of the central and western Mediterranean is poorly understood. Here, the authors generate ancient-DNA data from the Balearic Islands, Sicily and Sardinia, and estimate the level and timing of steppe pastoralist, Iranian and North African ancestries in these populations.
