Proveniências e utilização do sílex no Megalitismo de Lafões (Viseu, Portugal). Primeira abordagem a partir dos conjuntos dos dólmenes da Lapa da Meruje e de Antelas

Abstract

[PT] Os artefactos em sílex dos dólmenes da Lapa da Meruje (Vouzela) e de Antelas (Oliveira de Frades), cuja construção se atribui aos inícios do IV milénio a.C., foram analisados por forma a providenciar uma primeira imagem abrangente das estratégias de exploração, circulação e utilização do sílex no megalitismo da região de Lafões, uma das subáreas do importante núcleo megalítico da Beira Alta. Os conjuntos são formados sobretudo por geométricos trapezoidais, surgindo os segmentos em segundo plano. A origem do sílex pôde determinar-se para o primeiro caso (área de Rio Maior), sendo que em Antelas se observaram cinco possíveis áreas de aprovisionamento (por identificar). A análise traceológica revelou que a larga maioria das peças de Antelas não foi utilizada antes da sua deposição naqueles dólmenes; inversamente, os geométricos da Lapa da Meruje foram obtidos a partir lâminas previamente utilizadas e depois efetivamente usados como pontas de projétil. Nota-se, nestes casos, que as pontas foram encabadas transversalmente, uma técnica que já havia sido reconhecida na famosa pintura de arqueiro do dólmen de Juncais (Vila Nova de Paiva). No seu conjunto, estes primeiros resultados revelam uma elevada complexidade dos circuitos de abastecimento de sílex no megalitismo beirão. As diferentes intensidades observadas no seu uso significará também diferentes capacidades de aquisição de matérias-primas exógenas. A explicação para tais contrastes deverá radicar no quadro socioeconómico e na organização social destas comunidades.

[EN] The flint artefacts from the dolmens of Lapa da Meruje (Vouzela) and Antelas (Oliveira de Frades), which were built at the beginning of the fourth millennium BC, were analysed in order to provide a first comprehensive portrayal of its exploration, circulation and use in the megalithic region of Lafões, one of the subareas of the important megalithic clusters of Beira Alta. These assemblages are formed mainly by trapezoidal geometrics, followed by segments. The origin of the flint could be determined for the first case (Rio Maior area), with five possible supply areas (to be identified) being observed among the Antelas material. The analysis showed that the vast majority of the Antelas artefacts were not used before their deposition; conversely, the geometrics from Lapa of Meruje were obtained from previously used blades and later effectively used as projectile points. It should be noted in these latter cases that they were transversely hafted, a technique that had already been recognized in the famous painting of an archer at the dolmen of Juncais (Vila Nova de Paiva). Taken together, these preliminary results reveal a high complexity of the flint supply circuits in the Beira Alta megalithism. The different intensities observed in the use of flint artefacts will also mean different capacities for the acquisition of exogenous raw materials. An explanation for such contrasts should lie in the socioeconomic and social organization framework of these communities.
