 Kaj je to pričočne? Je to počkaj, da se zelo izvah na vseboje in urbanta formučne in je to je poslutno nekaj sega, da je zelo v compelling 11. svi. Na predseboj, bilo, da je zelo vseboj vseboj vseboj in vseboj vseboj vseboj vseboj sve bo večo tukaj na preziru medivalim rome. Vseboj, da bi se učila, da videl vseboj In zelo je v ročnih ročnih ročnih, in na delu ročnih ročnih, ki imam po ročnih z vseb, kako je v Aleztandro Molinari v zelo v Trvbergada. To je zelo, ki se na svoj ročnih ročnih ročnih počusti v nekaj zelo in je zelo v nekaj zelo v državci, z kateričnih ročnih na zelo v Madridu in Sandro Karocci v Trvbergada. To mi je počutito, da viče je v ročnih ročnih 1.600 budičnih, nekaj delovnih budičnih, zato v Čerjučkih, nekaj religijnih budičnih, zato Beltauer, Defensivtauer, vših, reštora, medivalnih, Defensivnih Romov, Volo Romov, infrastruktor, zato v vodnih, zato, nekaj delovnih budičnih budičnih arkeologi, ki pravimo, da imamo stajno tukaj data, in je biljamo kronor typologiji in seviacije v svojh teknikih, meneče, da je trajno v romiji. Kaj ni ga po všem slavu, kar 11 sem, je biljamo lepo informacijo. V seboj se data starta od nekakv delegu 11 in vseboj, kako je vseboj delegu vseboj, ki je vseboj delegu vseboj 12. Tukaj informacij je nekaj vsak, sa nekaj in obmačenih z vrštih vrštih. If we think about the reconstruction of the urbanistic development of room that, for example, you bear, give twice, we can add these three important points. A first phase of growth in the first 20 years of the 11th century has slowed down until the first 20 years of the 12th century and a new growth between the second half of the 12th century and the end of the 13th century. And although this last point is really known as the famous room and urban renaissance and we have a lot of study about there and a huge part of the building that we have in Rome are about this moment, we don't know nothing about the contests that produce this completely new evolution in the building in Rome. But if we look at all the data that it could be possible together for the end of the 11th century and the beginning of the 12th century what we can notice is the presence of a large increase of building activity about church, first of all. In connection with this huge activity that was in connection with the presence of the pope, Pascal II in Rome, it is possible also to notice the presence of other important element. In this moment, in fact, we have a series of elevation and levelling also up to 5, 4 and 6 meters in certain case and all conduct during one single phase. To give the example of these are the church of San Crisogono in Rome and the church of San, sorry, the church of San Clemente in Rome and the church of San Crisogono that are characterized in both by two overlapping buildings. So we have the ancient one, for example, in this case the blue one and at the end of the 11th century we have the new one built on the other but they are in use contemporary because we have trays of great user in both of them. This information is really interesting if we think at the organization of the city. All these information and all these series of elevation and levelling that we can notice also in some point in which we have a automotive house that is connected by Federico Vido Baldi at an important urban plan that involve especially road networking. But according to me these series of elevation and levelling is to connected to something that is more bigger than renovation of road and involve also water infrastructure seriography and in general the idea that we have of the city in this moment. Together in fact with all these transformation we can speak about another really important element the building of this river that you can see here. This is an artificial channel that we know was finished in 1122 under the Pope Callistus II. The stream that is the Marana stream in the reality is the deviation of another river that at the beginning move in the north of the city grow up in this point move then in the Indiana that is the first tributary of the Tiber and from this point move inside the city of Rome just a little before the Vatican so we are in the north of the city. With the deviation that from this point that you can see here move water in the south the water of the ancient river was connected with another river with this loose and then move close to the city of Rome in front of Porta Sinara. Here we are close to the ladder. By this point the water brings water to a lot of males. And then by this point we arrive into the city moving from Porta Metrona so the door, another door of the Aurelian wall was used by this river to move inside the city. By this point the river start to be a urban stream cross the Circus Massimon and then move into the Tiber, a little bit after the Tiber Island. So if we put all together all these elements here we put for you some evidence from excavation about the riverbed loose and the embankment that was found in the Circo Massimon. This is the nickname of the embankment that is really important and on which I speak to you later. If we put all together all this data about the stream what we can say is that the water moved from the north that point is the point in which before the deviation the water moved in the Tiber so just a little before the Vatican but after the deviation the water moved in the Tiber here. In one way we can say that with the organization of this deviation all this area of the city that is the place in which Roa, the real medieval city in the second half of the 12th century and then the 13th century was preserved. This is really important because this area is an area at risk of flows. So if we think these together with all the reveling it's not true that we have a lack of information about the building activity of Rome but what we can notice that is that we have in a certain way a kind of background a moment in which Rome looks like a building site in which everything was changed to transform the city. By this moment the city start to be something different from the early medieval city that we know composed by a kind of scattered settlement. After all this transformation the city became a cohesive town all inside this area. Then if we look at the position of all the point in which it could be possible to find all this change of arography what we can notice is that they happens all around these two roads that put in connection the ladder run with the vadigan. So by that moment vadigan and ladder run start to be the focal point of this new city that start to be concentrated in the middle. These two roads that I show to you are together the roads that compose the famous Via Papalis that is the road used by the pope for all the ceremony that from the ladder move in the vadigan and then come back. On this matter a comparison with other cities seems useful. In Newtonian period in the 12th century a series of intervention and urban renovation were made that connect the religious contests to the urban landscape allowing its vision from a certain distance and enhancing however its impact. In a large variety of solution adopted all implying however a willingness of intervention the example of Woodsburg Spira in Augusta seems appealing. If in the case of Woodsburg the sequence formed by the bridge the Don Straß and the Religious Building is interesting. In the case of Spira and Augusta here we see a monumental unity of the project. With no doubt the Via Papalis is far away from the Maximilian Straß of Augusta that were 40 meters wide but I believe however that the example is suitable for the intention of connecting permanently the city with the church defining in this way a main road for the control and use of city power within a cohesive urban space. Then one final consideration should be made on the economical importance of this intervention at least on the work of the Marana stream. The deviation of a river is not something irrelevant even more if one considers it within the large contests of transformation described that certainly implied a significant economical commitment. We are currently not able to quantify the cost of such a work but what we can say is for example, look at the Mansory Technique here we have the technique used in the embankment of the river that is the same that we can find in a lot of other buildings that are built at the same period that we have in Rome not inside the city but all around the city we don't have the use of this Mansory in Rome in this moment in religious building and this technique is the same that we can find in some of the restore into the uranium wall that are all concentrated in the south of the city that is the same point in which we have the passage of the Marana stream so what we can say is that all these elements recall in a certain way the civic context and allowing to suggest what looks like a possible secular collaboration in all this work in this moment of great transformation of course it's just an hypothesis and it's a new way of research that we start nowadays and so we need to have more data to confirm this but it's a really interesting element because from the original idea that we have at the city for all this study and from what Redenshurst told us what we can say that the end of the 11th century and the beginning of the 12th is really a background, really important for knows the medieval Rome. Thank you.
