 Here we are going to speak about ritual medieval deposit in a tumuli, in the northwest of Spain, in Galicia. Okay, there is only a limited tradition of studies of medieval pottery in Galicia, and these are predominated by a typological approach, with few studies prior to the year 2000. Also, the non-medieval contests have mainly been excavated in urban areas. There are surrounding areas as part of preventive archaeology projects. These contests are mainly domestic and funerary, while more recent studies have explored the architecture of charts and agrarian spaces. Another kind of site that has not been studied to date provides very interesting pottery. These sites appeared in the prehistoric and prothistoric periods and were reused in medieval times in very different ways. These types of sites present a number of problems. The first problem is that the information from the medieval faces is in a secondary level. Normally these sites are investigated because of the rage concentrating on the oldest faces. The second is that the medieval archaeological record has only begun to be systematically documented in the last few years. The third problem is that the presence of medieval activity is only mentioned briefly in the reports. In many cases, this information is only pasted from mouth to mouth between archaeologists and its own lust. Despite these difficulties, we find a certain variety of ways in which the oldest sites were reused during the medieval period. We know about hillfords. Here you can see two of them, like Castrovite on the left, Iron Age hillfort with a chapel on the top, or the other one on the right, Santa Maria de Cervantes in the province of Lugo, with a church over the hillfort. In this case, it would seem that the church, as an ecclesiastical institution, attempted to appropriate a space that still had some kind of pagan religious significance for the rural communities. Roman sites are known that contain medieval reused structures, such as the 10th century church built on the Roman encampment of Cigadella. You have it here, the Roman encampment, and the 10th century church is here, and then on the top they made a new Romanesque church over here. Recent excavation work has rebuilt medieval activity in prehistoric settlements. These are very complex sites, which are very occupied for long periods of time. The medieval activity is normally detected by chains from detains of structures that were previously considered to be prehistoric. Another kind of reuse, you have the Roman lighthouse of Hercules in Acorunia, is one of the oldest lighthouse in the world still in use, or the castle of Torres do Este, it was built in a hillfort and two in the Roman harbor. Well, megaliths were also occupied during the medieval period. Curiously, Galician archaeologists have traditionally presumed that tumult frequently contained medieval remains, but there are few publications that actually refer to this medieval activity. This is characterized by the presence of pottery fragments, in the last few years medieval activity has been documented in tumuli by radiocarboning detain, including a herd in the tumulus of Armamelas, for example, or a pit dug into a funerary complex detain from the Cermin Millennium BC at the Vesa dos Torradoyros, with identical characteristics to the prehistoric pits. Finally, at least 3,000 Galician tumuli were ransacked in modern times, leaving vain physical evidence, pottery fragments, and some wooden structures. Concentrating on the prehistoric tumuli, we believe that the reuse of these structures may have a functional and regular purpose. In the first case, the medieval activity has an economic objective. The space was occupied sporadically and seasonally in order to control the surrounding territory, which was used as grazing land or as good land. The location of the tumuli or headpoints in the terrain provided advantages. Look at the point. The associated archaeological remains include perishable structures or isolated fragments of pottery, poorly preserved, widely dispersed and small in number. In the second equally viable case, the medieval activity was the result of ritual practice. These structures were used for body deposits as they were prominent in this landscape and are usually associated with legends of legendary veins known as in Galicia, like Mouros. During the medieval period, these spaces lost their purely funerary significance but continued to be deeply rooted in traditional cultures. The specific contents of the pieces can help us to discover information about these types of rituals, which were possibly associated with the continuation of an implicit pattern in the lifestyle of these rural communities. We believe that the tumuli of Rosa de Azeveas provides a clear example of a medieval ritual space, even though they also had a functional purpose and that is the choice of the localization in the landscape and the position of the items on the site in not purely by chance. Our aim is to demonstrate that this deposit is ritual, characterizing the pottery found on the site from a special contextual and formal perspective, considering its typology, morphological, technical features and decorative elements, as well as from an analytical perspective by carrying out physical and chemical analysis. The Necropolis of Santa Marina of Rosa de Azeveas containing around 32 tumuli is located in an extensive plain around an important transit route that crosses the entire municipality district from North to Southwest. Today, the Necropolis still stands inside an industrial state and a series of excavations have been carried out in the area, mainly focusing on the double tumulus. A total of four tumuli were excavated in this Necropolis, one of them was built over a circular enclosure surrounding my trench in which only three medieval pottery fragments were found. In the second tumulus of Rosa da Fora, no medieval fragments were found and finally, a double tumulus, the subject of our study, where a large number of pottery fragments were found. The double tumulus is close to a natural transit route. The distance between them is like two or three meters and they are oriented north-west, giving the sensation of being a single unit as they visibly overlap each other on the horizon. When seen from all of the angles that provide access to the two tumuli, this visual effect seems to have been created deliberately, probably with the aim of intentionally demonstrating that they belong to the same construction scheme or design. A number of periods of reuse, posneolitical, were documented from subsequent periods throughout modern times. During the process of construction and reuse, a number of different objects were deposited. In this case, we are interested in the medieval activity, which is quite exceptional in the region. We have a total of 15 medieval vessels with similar features to other types of pottery from the early medieval age. The features we will go on to describe dates from between the 8th and the 11th century. These vessels are highly fragmented and have the characteristic of domestic ware used to cook and serving food. They mainly consist of pots. There are also numerous vessels with handles, such as bottles, pictures and jars. There are three types of clays that have been identified. The pots have three types of clays, which, while the other types, are reddish in color. They were manufactured using a wheel, a modeling technique seen in the pottery made of black and orange clays. Together, we have made vessels using the reddish clays. They also have a very regular finish on the outer surface and emicaceous temper. Only four decorated vessels were found. With typically medieval designs, they were limited to straight vertical lines or curved horizontal lines in thesis or stamped using a punch. They are all made of red clays and there are no decorated pots. The most outstanding aspect of this double-neurotic tumulus is that the medieval pottery is the most abundant and best-structured type in the site, despite the fact that it appeared in the surface levels of the noreth of the tumulus over the natural soil without any structures associated with the deposit. Initially, it was construed as having been a rubbish dam where fragments of pottery had become accumulated in a perimeter part of the site. But after carrying out a formal and spatial analysis, it was found that it had futures suggesting it had been deposited intentionally in relation to the monuments. The choice of the location in the tumulus suggests a major change with regard to prehistoric reuses of the site on the side of the tumulus but outside of it. The pieces were preserved in a virtually completed condition and their fragmentation is a result of the post-depositional process. The distribution of the pieces rebelled a homogeneous collection that was deposited at a single moment with a main concentration and some pieces that were subsequently scattered over the tumulus. As a result, the medieval pieces are located in a specific context. In an ancient double tumulus whose use and significance lasted for a long period of time and which went far beyond the original intation of its builders. We decided to carry out an analysis of the clays, use it for the pottery in order to verify if this hypothesis was supported or not by a more complete characterization of the pottery. A total of six pieces that were representative of the clays and shapes were selected. One of the pieces had decoration. Two types of analysis were carried out, X-ray diffraction to determine the mineralogy of the sample and X-ray fluorescence to quantify their chemical composition. The results are found in the following tables. The main geochemical and mineral geological results are detailed below, focusing on different aspects of the pottery's production. Amongst the argumenting results, we found that the vessels have a quartz plagioclase mineralogy and a current elemental composition with a high content of silica, aluminium and iron and titanium, which is current with the element of composition. The geochemical and mineral geocomposition leads us to consider the granitic sketch type of clays. So, there are local vessels. Also, Galician soils are considered as granitic. There is a variety of raw materials available in the surrounding area where the following lithologies can be found. In quartz, narrow bands of alkaline granites, large plates of caulk-alkaline granites, in order to facilitate the identification of the raw materials with the most likely sources, the result of the elemental composition of the pottery were compared with several sea-horizon samples in the different lithologies. The comparison is excluding other minerals that are more associated with the post-depositional period. The underground was obtained showing that two clear groups were formed and how the different sea-horizons are grouped in different types of pottery. Whatever the case, all of the evidence we have available so far would seem to indicate that the raw materials were always extracted locally at different distances, ranging between in situ and a maximum of 12 km. Therefore, we can consider that the collection of pottery was possibly manufactured by two different potters or pottery workshops. Plagio clays and quartz are the main materials used as tempering the clays. We do not have any evidence that would indicate that the tempers were added intentionally. Also, there may have been a prior selection of raw materials bashed on the swatibality for the type of pottery to be made. As despite having a wide range of raw materials available in the surrounding area, the potters only selected a skis and granite. The pottery was fired at a temperature between 500 degrees and 900 degrees. The visual difference found in the clays is not a result of their composition, but instead of a fairing atmosphere with a higher or lower oxygen content. The abundance of phosphorus in one of the vessels might have due to shoot on its surface in carbonized sizes residues. On its walls are a result of the vessel being used, although we have ruled out that this may be post-depositional, and this indicator is much weaker in the rest of the pieces we analyzed. If it were post-depositional, we would have detected it in a similar concentration in all of the pottery. We consider that the characteristic of the deposit conferring its ritual purpose, and that it was intentionally concealed. The choice of the double tumulus seems to have come about as a result of a consistent action carried out on an element that was important in a space and in the territory in general, as it has been reused over many thousands of years. This landmark was deliberately chosen perhaps because it corresponded to an exceptional type of design amongst Galician-Megalitic structures. This is not a waste pit. If it were a waste pit or a casual deposit, we would expect a greater variety of morphotypes, greater fragmentation and a more width dispersion around the spatial distribution. All of the features of the pottery confer its homogeneity at a morphological level, only broken by the vessels with handles. The decorated pieces that were chosen are red and exclude the pots. The clays are also similar. The variety is in the color of the surface, the position, the processes of missing the temper are simple and from the same source areas. Homogeneity in the firing process with similar temperatures, the difference in color may be due to the position of each piece in the kiln or because several kiln lows were fired. Search for re-materials in their nearby litological surroundings, which was well known, the people who deposited the offering knew the area and which they were operating well. The existence of medieval activity in Tumuli is known, although it has not been documented to any extent in our region. However, the characteristics of this deposit make it exceptional in Galicia. There can be no doubt that there is an urgent need for study of medical archeology to be set underway in our region and in particular those oriented towards obtaining a more thorough understanding of the context in which pottery is documented. As this may help us to understand many different aspects of historical communities that are not dealt with in the limited documentation. Thank you very much.
