A paper was recently published on
Perdigões temporalities. It can be download here.
Based in a set of 35 radiocarbon dates, an
image of progressive growing of the site is emerging. Starting with to central
enclosures dating from Late Neolithic (second half of the 4th millennium), grew
bigger with the intermediate wavy ditches dated from the second quarter of the
3rd millennium and finally with construction of the ditch 1 in the topo of the
amphitheater slope in the second half of the 3rd millennium.
However, this image of a progressing
growing must be seen as provisory, since several ditches still to be dated,
namely the one that runs partially out of ditch 1 and is cut by it. If this
ditch is older, Neolithic for instance, than the site was big since the
beginning.
This is an important step into the
Perdigões temporalities, but is still just a step. Further research is needed
to provide a complete image of the diachronic development of this impressive
set of enclosures
