"The Archaeology of Roman Portugal contributes to the wider debate on Roman imperialism and expansionism, by bringing to the fore a much-underrepresented area of the Roman empire, at least in English-language scholarship: its westernmost edge in modern day Portugal. Highlighting the perspective from Roman Portugal contributes to our understanding of the Roman empire, through presenting both an extraordinary landscape in the sense of economic opportunities (ocean resources, marble and metal mining), and also settlement history. The volume presents new data and insights from both archaeology and ancient history, discussing their significance for our understanding of Roman expansion and imperialism. A key goal of the volume is to discuss how the Portuguese panorama compares to other areas of the Iberian peninsula, and to better integrate Portuguese scholarship in the academic debate on the Mediterranean Roman world, and to contextualise it firmly within the wider Iberian and Western Mediterranean. The volume brings together an internationally diverse team of scholars in archaeology and ancient history from Portugal, Spain, Germany, the UK, the US, the Netherlands, Belgium and Italy. It explicitly discusses different national and disciplinary research traditions and historical frameworks in order to assess the potential of integrating best practices in archaeological approaches and methodology"--

Over the past decade, high-resolution noninvasive sensors have been widely used in explorations of the first few meters underground at archaeological sites. However, remote sensing actions aimed at the study of structural elements that require a very high resolution are rare. In this study, layer characterization of the floor mosaic substrate of the Pisões Roman archaeological site was carried out. This work was performed with two noninvasive techniques: 3D ground penetrating radar (3D GPR) operating with a 1.6 GHz central frequency antenna, which is a very high-resolution geophysical method, and photogrammetry with imagery obtained by an unmanned aerial vehicle (UAV), which is a very high-resolution optical method. The first method allows penetration up to 30–40 cm depth and 3D models can be obtained, and with the second method, very high detail surface images and digital surface models can be obtained. In this study, we analyze a combination of data from both sensors to study a portion of the floor mosaic of the Pisões Roman Villa (Beja, Portugal) to obtain evidence of the inner structure. In this context, we have detected the main structural levels of the Roman mosaic and some internal characteristics, such as etched guides, internal cracking, and detection of higher humidity areas. The methodology that we introduce in this work can be referenced for the documentation of ancient pavements and may be used prior to carrying out preservation activities. Additionally, we intend to show that a Roman mosaic, understood as an archaeological structure, does not consist of only beautiful superficial drawings defined by the tesserae, but these mosaics are much more complex elements that must be considered in their entirety for preservation. ; This work is co-financed by the INTERREG 2014-2020 Program, through the project, "Innovacion abierta e inteligente en la EUROACE" with the reference 0049_INNOACE_4_E; by the European Union through the European Regional Development Fund, included in the COMPETE 2020 through the ICT ...
