The lithic assemblage from Lapa da Galinha (Alcanena, Portuguese Estremadura) and the “Cave Megalithism” phenomenon in the 4th and 3rd millennium BCE

The present work proposes to present the analysis results of the flaked stone artefacts from Lapa da Galinha, a cave necropolis, located in the Estremadura Limestone Massif, that is a classic example of the funerary practices of the 4th and 3rd millennium BCE. The excavation dates back to 1908, and it was performed by members of the current National Museum of Archaeology, resulting in an extensive votive ensemble, associated with a minimum number of 70 burials. The evident collective nature of the burials, the votive ensemble and the rituals there identified emphasise its “Cave Megalithism” character, an expression that invokes only one of the many facets of the complex phenomenon that is Megalithism. Since the Megalithic funerary structures, such as natural caves, are utilized over a long period of time, it’s not easy- but not impossible- to reclaim in full, the events that took place. Focusing on the flaked stone artefacts, the main goal of this text is to contribute to the reconstruction of the belief system that characterizes the Neolithic and Chalcolithic communities from this region. Hence, the morpho-technological criteria, that followed previously established standards, and raw material analysis of the artefactual categories, even on a macroscopic level, were absolutely essential for us to suggest an extensive diachrony of the funerary use of the natural cave With that in mind, we reflected on the importance of the transformations that occur within the material culture exposed throughout the text and their chronological meaning, but also on the true potential of this artefactual category as a tool to build a solid perspective regarding the symbolism inherent to these funeral practices
