Cup-marks on a small outcrop, close to the tallest dolmen in the world (Anta Grande do Zambujeiro). Between the cup-marks and the dolmen (and beneath this one), a neolithic settlement has been identified.
This situation ( a burial monument overlapping a former settlement site) has been proving to be very usual, in Iberia as in other areas of Europe.
Close to the town of Mora (Central Alentejo) we find another cluster of pre-historic setllements and ritual sites apparently in connection with the bend of the Raia.
The C (or horseshoe) plan of sites like Águas Frias (or Poverty Point) is also the usual setting of megalithic enclosures, in Central Alentejo and Brittany.
Rare in the British Islands, is also displayed on the unique site of Stonehenge; this has been argued to reveal some kind of relationship between Stonehenge and the Continental Europe, on Neolithic times.
The Late Neolithic settlement of Aguas Frias, in Central Alentejo, seems to display a symbolic architectonic plan which could be interpreted as a sintesis of the same symbols displayed on the two mississipian sites showed on the last posts: the semi-circular plan of the earthworks in Poverty Point and the snake-like plan of Serpent Mound.
Águas Frias has been interpreted as a settlement site, though it showed a very unique caracteristic which gives an extra symbolic dimension to the site: it is the only known "factory" of the highly symbolic shist plaques that caracterize the deposits in the alentejan dolmens (as well as in the areas around Alentejo).
Where are the limits between a settlement and a ritual site?
Again in the USA, in the Mississipian world, the biggest representation of an almost universal icon: the serpent. Note that the Serpent Mound describes a hemicycle, open to a small river.
In the same general area we can find other earthworks displaying animals.
The earthworks of Poverty Point, an ancient ritual site, with a set of concentric ditches and banks, drawing a semi-circular plan. The enclosure opens to a bend of the sinuous Mississipi River.
The well Depiction of a zig-zag/undulating line, on the Alqueva pannels of Retorta
Rocha da Mina (Alandroal) is a pré-roman sanctuary, eventually devoted to the celtic god Endovellicus, with some rock cut features, such as a stair, a well and an altar. See http://www.crookscape.org/news.html
The location of this santuary, in a difficult landscape, seems tighly related to a bend of the River Lucefece.
The importance, for the prehistoric mind - in what respects the implantation of sacred sites - of the bends of the rivers, showed on two major european ritual sites (see the two previous posts), is very well exemplified on the Alqueva rock art. Actually, the most important concentrations of carvings are located close to the two major curves of the Guadiana river, called, in portuguese, respectively, the Moinho da Volta and Retorta, both refering to the acentuated bends of the river.
The Bend of the Boyne is a extraordinary megalithic complex, in Ireland, the biggest concentration of megalithic art in Europe, Three main monuments (Newgrange, Knowth and Dowth), and other smaller elements, integrate this very defined megalithic landscape.
The name of the area relates to the waving course of the Boyne River.
Escavações em Durrington Walls, um recinto de fossos, relacionado com Stonehenge. Note-se o curso sinuoso do rio Avon, com o qual se articulam ambos através de avenidas.
O conjunto inclui Woodhenge (aqui representada uma reconstituição feita em 2005).
Pedra das Gamelas (Santana do Campo, Arraiolos, Central Alentejo)
The issue of rock cut basins/versus natural basins is not a new one. Here I include images of a natural outcrop with carved antropomorphs (cruciforms) on the sides and a natural basin on the top. It has been first published by Vergílio Correia (El Neolítico de Pavia, 1921). This author comments the difficulty of distinguishing natural and artifitial basins (as well as the "normal" cup marks) suggesting that the latest would have been inspired on the former.
