0373 - Updating phalanx idols at Perdigões

During the coming summer solstice (not exactly, but in Sunday) the Era team will be observing the sun rise in the alignment of gate 1 again at Perdigões. During Saturday we will be at Esporão farm to guide visitors (of the Big Day event) to the exhibition of Perdigões in the medieval tower of the farm and to the deposit of materials.
I am using part of today’s holyday to prepare some materials to be shown in the deposit. Taking the phalanx idols form the plastic bags and arrange then in a box, so they can be easily appreciated.
And when I was doing this I noticed the similarity between the fracture in a phalanx collected at the surface of tomb 2 and another fragment collected at the surface of tomb 3, recently excavated and just 10 meters away.
They fit. They were both considered as different elements in my paper about the phalanx idols of Perdigões (the drawing of the top part was even presented). Now that they are reunited a new object emerged: the zig-zag hair in the back (although horizontal and not vertical like the other peace from tomb 2 – see publication) and the eyes and the arms (possibly holding something) in the front. Very similar to the other one already published, but with arms. It needs to be better cleaned now.

I always argued that keeping things in site has its benefits for trained visual memories.

The paper (see here), that addressed the phalanges but also the horse domestication problem, can now be updated. Well, not entirely: there are some more new phalanges from recent excavations that enlarge the already impressive numbers of these items at Perdigões enclosure.

0372 - Molluscs and shells at Perdigões enclosure

New paper on Perdigões enclosure. This one about the social role of molluscs and mollusc shells in the site. The main conclusion is that the consumption of molluscs and shells is mainly an issue of ideology, rather than subsistence, in the context of transregional interaction and use of exogenous materials. The majority are sea or estuarine species and, of those, it was the shell (not the mollusc) that circulated the most. Pecten maximus is one of the main presences, but in different contexts according to chronology: in depositions in ditches and pits in the Neolithic Perdigões, and a lot in funerary contexts during the chalcolithic. These and some other interesting aspects of molluscs use at a local and regional scales are discussed in the paper (in Portuguese), where large ditched enclosures show differences regarding smaller open or walled sites.

0371 - Workshop on Prehistoric deposition and fragmentation practices

Depositions and fragmentation, as intentional and meaningful social practices, are common in many European prehistoric enclosures. The same happens in Iberian ones, although not always perceived, conceptualized, and questioned as so.

To encourage the debate and research of such subjects in Portuguese archaeology the following workshop was organized and will take place in Lisbon, in 14 October. We have chosen a small auditorium of a public book store to do this. We also want to encourage the public interest.

0370 - Perdigões: 20 years of research

The Perdigões Research Program completes, in 2017, twenty years of continuous activity. Directed by Era Arqueologia, a private company, the program has established many collaborations with researchers and institutions at a national and international level, and continues to do so. This policy of open collaboration has turned Perdigões in a central context in Portuguese archaeology of Prehistory, with significant international projection. It is an emblematic project of the Portuguese Prehistoric Enclosures. Two decades of research of a site that lived for at least 1500 years gives a good idea of what remains to be done. The project is sound, though, so an interesting future is to be expected. Perdigões has a lot to give. The ability to "extract" it depends entirely on us (collectivelly)

0369 - Back to Perdigões

The excavations return to Perdigões ditched enclosure next week. The 20th campaign is about to begin. The work will be focus in the excavation of Tomb 3, in the eastern limits of the enclosure, and in the central area, continuing the excavation of the contexts detected there last season.
As usually, the results may be followed in a daily basis in here

0368 - Salvada in the press

The impact in the large enclosure of Salvada, that was discussed here some posts ago, is in the front page of a national paper and has a significant report inside. As it happens in many other things in life, only when some bad happens things get to the front page. That is the criteria of the media, maybe because that is the criteria of the majority of the public.

Nevertheless, it is an important report for the Portuguese Prehistoric Enclosures, for they dramatically need this public exposure to be known, protected and start to be socially active as the important heritage and economic and cultural resource they are.

0367 - In fact, they are TWO

Just side by side. A closer look, with some colour control, shows another smaller enclosure just next to the bigger one (that show 4 and not just 3 diches). This is another important site to deal with the problem of the temporalities of enclosures and their periodic rhythms.

0366 - A new one: number 75

A new ditched enclosure (Monte de Corte Ribas 5) was identified in the context of a Master thesis (Silva, 2015). It presents at list 3 concentric ditches. It is of Chalcolithic chronology. It is number 75 in my inventory.

0365 - Dramatic and continued

Salvada. 2/3 afected by a deep ploughing.

The partial destruction of prehistoric enclosures in Portugual continues. The large enclosure of Salvada (around 18 ha) is the later victim. In Alentejo region, after the construction of the large dam of Alqueva, a water supply network is being built. Many archaeological sites have been identified in the context of the assessment programs of that project that dramatically changed the knowledge about the Prehistory of inner Alentejo.

But a new problem emerged. One that has not an adequate response from the responsible institutions. The supply of water is generating a profound change in the agriculture in Alentejo. The region is being invaded by vineyards and especially by olive tries fields that have a huge impact in the soil, because the ploughing is deep and very destructive.  

But if the water supply channels, or highways, or high voltage powerlines, have to do impact assessment studies (and assume mitigating measures for heritage), these agricultural transformations have not. And the municipality plans for territorial management (PDM) are not being attended. The result is obvious. Heritage is being destroyed at an increasing rhythm, and prehistoric enclosures are one of the main victims.

An example of the absurd ways of a “law state” (Estado de Direito) or of the hypocrisy of the modern times. Meanwhile, sites after sites are being destroyed. Small cerebral veins shutting down until the final collapse of memory.

0364 - They keep appearing.

At Perdigões enclosure we are now studying the several funerary structures in the context of the project “Mobility and Interaction in South Portugal RecentPrehistory: the role of aggregation centers”. One of the structures is Pit 40, where cremated human remains were deposited. There are thousands of small fragments of burned bones that are being studied in anthropological terms, and among them fragments of ivory items, also burned, keep appearing.
Several represent parts of anthropomorphic figurines like the ones from the same general context already studied and published (Valera & Evangelista, 2014).
Here is the head of one that lost its face. It presents the hair, the ears and even the final traces of the facial tattoos.

A head like the best preserved one, only smaller.

Number of these figurines is now higher than what it was published and will probably grow as the study of the bone fragments progress. The figurines, like the human bodies, are all in small fragments and burned. Would have this analogy been intentional?

On the contrary, the exception above, when deposited, was intentionally completed in a broken leg with a burned white bone (see publication). Body segmentation and body integrity, parts and wholes. Or windows to the Neolithic mind. Something to be discussed in a coming workshop in Lisbon.

0363 - Astronomic orientation of gates: also documented in Spain

Orientation of NE gate at Camino de las Yeseras (After Liesau 2013-2104).

The cosmological and astronomic bond of ditched enclosures architectures in Iberia was first addressed in Portugal (Valera 2008; Valera, Becker 2011, Valera 2013). In the context of that research, it was noted that several ditched enclosures present topographical locations towards East and that several of them have their gates aligned with the solstices and/or equinoxes at sunrise and/or sunset. Those are the cases of Perdigões, Santa Vitória, Outeiro Alto 2, Xancra or Bela Vista 5 (see issues in the lateral bar).

These perspectives and analysis have now also been developed for a ditched enclosure in Central Iberia. At Camino de las Yeseras a NE gate seems to be orientated to the Summer solstice at sunrise, and the sections of the ditches that define that entrance show evidences of intentional depositions interpreted as foundation rituals (Liesau et al., 2013-2014).

Something that will become more frequent, once we have access to more complete plans of enclosures and have in mind that architecture tends to be holistic

0362 - Ditch of Carrascal 2 presentation

Ditches do not always enclose. At May 15th it will be presented the study of a ditch that was used as an atrium to access several funerary hypogea and was itself used for secondary depositions of human remains, some cremated and some don’t. It is dated from the Chalcolithic and is located next to the large complex of enclosures of Porto Torrão (South Portugal).

0361 - A new possible ditched site in Lisbon

In excavation by ERA Arqueologia, there is a new prehistoric site in the center of Lisbon, possibly Neolithic, that shows a small irregular ditch, very similar to the ones excavated in the Neolithic site of Senhora da Alegria (Combra, central Portugal).

0359 - Addressing interaction at Perdigões – the shells (1).

Patella candei (Lapa Mansa) proveniente do Sepulcro 1 dos Perdigões

The Portuguese large Prehistoric enclosures present many differences regarding the smaller ones: apart from size, they have longer and more complex biographies, evidences of a multitude of social practices (including manipulation of human and animal remains and funerary practices) and show that they were engaged in large interregional networks of circulation of people, animals and exotic goods.

Perdigões is a good example of this large scale interaction developing from the second half of the 4th millennium BC and increasing during the 3rd. A paper addressing the exogenous at Perdigoes is about to get published, but another is being written specifically about one item: the shells. A significant number are shells from salty water molluscs, with probable provenance in the coast of Alentejo and the estuaries of the Tagus and Sado rivers.

Though, this shell of Patella candei, with 8,4x6,7cm, is not from those areas. This species is from warmer waters of Madeira and Canarias islands and the coast of Magreb. Like the ivory already analysed, its origin is probably in Northwest of Africa, documenting that at Perdigões enclosure exogenous items of extra peninsular origin were arrinving.

PS – Last week we just found out that there is also Amber at Perdigões, reinforcing this picture.
