Des archéologues espagnols conduisant des recherches sut sur les populations de l’age du bronze de la côte de Valence prés de Séville, rapportent avoir découvert dans une chambre mortuaire une pierre tombale de2 mètres pesant plus de 2 tonnes.

Ils n’ont pas encore découvert d’ou elle pouvait provenir puisque c’était la première fois qu’ils trouvaient une pierre de cette taille et qu’il ne s’en trouvait pas dans la région. Les sculptures que comporte cette pierre indiquent qu’elle était utilisé comme pierre tombale entre 4.500 et 3.700 bp..

Or les carrières se trouvant dans la région sont à une distance de plus de 55 kms. La pierre ne pouvait avoir été apportée que par la mer, nécessairement sur des embations ressemelant à de grosses piroques

Les égyptiens de l’époque des pharaons avaient déjà maitrisé cette technique. Les populations cotières espagnoles pouvaient elles avoir eu avecvc une avec eux des contacts suffisant ?

Highlights•

• •A large square stone basin made of gypsiferous cataclasite occupies the chamber of the tholos

• •The transport of the rock to Valencina most plausibly implies the use of some kind of boat

• •The basin must have been placed on its current position at some point between 4544 and 3227 BCE

• •The construction of the tholos of Matarrubilla must have been later than the placement of the basin

Abstract

A broad multidisciplinary approach is deployed to study an exceptional megalithic feature: the stone basin that presides over the chamber of the Matarrubilla tholos, part of the Valencina Copper Age mega-site (Sevilla, Spain). The study, including geoarchaeological characterisation and sourcing of the stone, traceological analysis of its surfaces based on photogrammetry and morphometrics, digital image analysis as well as OSL dating, leads to a number of substantial findings of great relevance to understand the significance of this stone basin, the only of its kind documented to this date in the Iberian Peninsula, with parallels only in Ireland and Malta. Among the most relevant conclusions, it is worth noting the fact that the gypsiferous cataclasite block the basin was made of was brought from the other side of the marine bay that five thousand years ago extended across the south-east of Valencina, this is the first evidence of waterborne transport of a megalithic stone in the Iberian Peninsula. In addition, the basin appears to have been put where it stands today sometime in the first half of the 4th millennium BC, long before any tholoi were built at Valencina, which suggest a prior history of still poorly documented monumentality at this mega-site.
