0411 - New image of the new affected one

The enclosure of Nobre 2 was discovered in Google Earth and published by me and Tiago do Pereiro in 2013 (Valera, Pereiro, 2013). It was recently affected by agriculture, as reported in the previous post. Here is a new aerial image of the enclosure (from EDIA), where the ditches are must more clear and we can perceive an alignment of three gates orientated at 140º. It might be  very similar to Xancra and to the recently prospected Borralhos.
 It is important to do, at least, some geophysics there before the plantation.

0410 - Another enclosure affected by agriculture

It doesn't stop and just gets worth. In Alentejo, archaeological sites continue to be affected by the agricultural changes, and if in some cases there is preliminary archaeological work, in many other situation sites are affected or destroyed and nothing or very little happens.

This is another situation of a Chalcolithic ditched enclosure, with at least three concentric ditches, detected in Google Earth and published and reported to the Municipal Plan, that was recently affected by the preparation of the field for another plantation of intensive exploitation (almonds or olive trees).

Heritage is being destroyed at an impressive rhythm in Alentejo.

0407 - Discussing the end of prehistoric ditched enclosures

Next weekend (16-17 November 2018), in Coimbra, the transition between the 3rd and the 2nd millennium BC in Western Iberia will be discussed. This is the moment of the twilight of ditched enclosures in Iberia. The reasons for the collapse of the social trajectory of Neolithic and Chalcolithic societies will debated as well as what followed.

My contribution: Death in the Occident Express: reasons for a social collapse in the end of the 3rd millennium BC in Iberia Southwest.

0403 - The twilight of Perdigões

In next September 24 and 25 I will be presenting a synthesis of the available data on Perdigões later phases of use. It will be at a workshop promoted in Lisbon by a team from the Kiel university that is interested in the problems related to climate change occurred by the end of the 3rd millennium BC and their repercussions in the social trajectories of the time. The confluence of interests (the next project that is being designed for Perdigões dedicates particular attention to the social changes in the Late Chalcolithic / Early Bronze Age) has been leading to a collaboration between this university and ERA Arqueologia regarding ditched enclosures (at the moment, we are collaborating in completing the geophysics of Monte da Contenda).

0402 - Santa Vitória: the usual

The work in Santa Vitória has been mainly cleaning. Namely the already excavated ditches, from which there is no new information to collect. 

But in ditch 2 we started to define a new section and the top of preserved fillings, and the expected is there. Like in many other ditches of many other enclosures, Santa Vitória is also presenting recutings filled with layers of stones.

0401 - SANVIT 2018_2021

Visit to Santa Vitória in the context of the international meeting organized by ERA in 2012 (Gulbenkian, Lisbon) on "Ditched enclosures and funerary practices", later published in the British International Reports.

Next Monday the project "Santa Vitória: temporalities, Architectures and Social Practices in a ditched enclosure - SANVIT", developed by Era Arqueologia in collaboration with Campo Maior municipality and DRC of Alentejo, will start, with the first campaign of field work, co-directed by me and Ana Catarina Basílio.

The project is linked to the Perdigões enclosure's one, not just because of the institutions and people involved, but mostly by the scientific inquiry, as can be deduced from the project abstract:

" The project is focused on the ditched enclosure of Santa Vitória (classified as site of public interest, and property of the State) located in the municipality of Campo Maior, Portalegre district. It aims to apply a scientific inquiry that allows the comparing of the social dynamics and the temporalities of a small ditched enclosure with the ones that have been identified in a large complex of enclosures such as Perdigões.
It is intended to produce information that responds to the present problems involving ditched enclosures and that, simultaneously, allow the construction of a comparative frame for different/similar dynamics observed in Perdigões. We want to comprehend how two apparently different biographies can be integrated in a frame of shared principles, but expressed in distinct ways and durability. Therefore, the project will be developed in strict connection with the Perdigões Global Research Project.

The specific main goals are:

- Obtain the global plan of the site through geophysics;
- Built a chronological frame for the site and establish its temporalities;
- Characterize the social practices that took place at the enclosures and its periphery and the processes of filling of negative structures;
- Determinate the levels of interaction, in terms of exogenous materials and mobility of animals and (if possible) humans.
            - Characterize the material culture accessing style and technology;
            - Contextualize the site in the local settlement network;
            - Evaluate the conservation situation of the structures previously excavated and exposed for several decades and define a plan of intervention, aiming the preservation of the site;
            - Develop a program of public display and heritage education associated to the site.

For starting, though, we have a hard task ahead, for the site is covered with bushes.

0399 - Santa Vitória. The new project of ERA at a ditched enclosure

It has just been approved a new research project, promoted by the ERA team (in a partnership with the DRC-Alentejo and Municipality of Campo Maior), to approach the ditched enclosure of Santa Vitória, at Campo Maior, Alentejo. This project aims to compare the social dynamics of a smaller enclosure with the ones of a large and complex one as Perdigões. So, the two projects will be in sound articulation.

0391 - New paper about Perdigões.

A new paper about Perdigões has just been published. It addresses Tomb 2, a tholoi type monument, with construction dated from the first half of the 3rd millennium BC, but with a later use in the second half of that same millennium, in beaker times, with some beaker items (like gold foils and ivory button), but with no beakers. Something that is common in Perdigões, as the next paper, coming out tomorrow, discusses.

0390 - New Master Thesis about Perdigões

A new Master thesis was defended at the University of Algarve about the social role of Bell Beakers at Perdigões enclosures. The studied context confirmed a previous idea that beakers were added to a ongoing social trajectory and do not represent a rupture or structural change in that trajectory. And that Beakers have diversified social roles, that, in a context of a wider scale of shared ideas, present regional heterogeneity that cannot be reduced to "monotetic" theoretical formulas.

0389 - More ivory while selecting teeth for mobility analysis

Some ivory items, with focus on the decorated plaque.

In the context of the project to characterize human mobility at Perdigões enclosure we are enlarging the sample of Tomb 2. We have been reviewing the bones and selecting teeth, namely from some stratigraphic units not yet studied. Bones were still packed from the field, and mixed with them some more votive materials: arrow heads, beads and ivory items.

Some of the ivory items are decorated fragments of plaques, with geometric motives, that are similar to others present in other Southern Iberian large ditched enclosures, like Valencina de la Concepción. With the conclusion of the study of Tombs 1 and 2, and the ongoing study of the cremated remains of Pit 40, the paper about the ivory items in Perdigões, published in World Archaeology (Valera et al, 2015), needs a significant updating.

Teeth to be selected for analysis

Other votive materials

And an item from Valencina similar to the decorated fragment from Tomb 2 of Perdigões (taken from Garcia Sanjuán et al, 2013)

0388 - Preparing for excavating Tomb 4 at Perdigões

Click on the image to enlarge

To prepare the excavation of Tomb 4 at Perdigões Era team did some more geophysics to improve the available image. Here you may compare the previous image (on the left) of the monument with the new one (on the right, over the previous one). The difference is remarkable and a lot of useful information about the architecture is provided.

We will starting to adopt this procedure to other specific areas of the enclosures to get more detailed information.

0387 - Perdigões Tomb 4

Yesterday the Era team went back to Perdigões to do some more geophysics. This year, another tomb will be excavated in the context of the project on human mobility. This tomb was already identified in the published magnetogram, but now we manage to improve the quality by using another measuring grid.
It is clearer now that it looks like another monument with a circular chamber, small passage, like Tomb 1, also oriented to 90º. It also seems to have some sort of mound still preserved.

This image will be of great help for planning the excavations.

0386 - A new image...

... of Monte de Corte Ribas ditched enclosures. In this image, we can see the three circle enclosures, and one or two smaller circles in the north part. One seems to overlap the outside ditch of the three ring system.
