The villa was an important feature of the Roman countryside intended both for agricultural production and for leisure from the 2nd century BC onwards. It has also often been treated in Roman literature; manuals of Roman agriculture give explicit instructions on how to select an ideal location for an estate as well as where to place the buildings. The ideal location was a moderate slope facing east or south in a healthy area and good neighborhood, near good water resources and fertile soils. A road or a navigable river or the sea was needed for transportation of produce and for reaching the estate easily. In addition, a market for selling the produce, a town or a village, should have been nearby. These recommendations are often cited in research literature, but have never really been examined in detail. The research area is ca. 500 km² in the surroundings of the city of Rome, a key area for the development of the villa. The materials used consist of archaeological settlement sites collected from published survey reports, literary and epigraphical evidence as well as environmental data. The sites include villas as well as all other settlement sites from the 7th century BC to 5th century AD to examine development and changes in the tradition of site selection. Geographical Information Systems were used to analyze the archaeological and environmental data based on the hypotheses derived from the written sources. Six aspects of location are examined: geology, soils, water resources, terrain, visibility/ viewability and relationship to roads and habitation centers. Geology is not explicitly mentioned as a criterion for site selection by the Roman authors, but it was important for finding building materials as well as for the stability of the buildings. The analyses show that the large villas established in the 2nd century BC tend to be located close to sources of building stones. Fertile soils were, on the other hand, very important. The productive areas were sought even in the period of the densest settlement in the 1st century AD. Even the poorest zones were used intensively during the same period. The Roman region is rich in water, both rainfall and groundwater. Water was also important for pleasure as well as for display of wealth and status. Excessive water, however, could be a problem and the research area was riddled with malaria in the early modern period. Although the Roman region may already have been troubled by malaria in ancient times, the settlement density testifies that the disease could have not been as devastating as it was later. Acertain kind of terrain was sought over very long periods, showing the strength and the success of the tradition. A small spur or ridge shoulder with an open area in front of the site was selected for most buildings. Slopes facing east or south are not very common in the area, but the southern ones were sought. The eastern aspect might even have been avoided in order to catch heat-reducing breezes in the summer and to miss the cold winter winds blowing from the east. Visibility was studied both as the opportunity for views from the site as well as the viewability of the building in its surroundings. The most popular villa resorts in the region are located on the slopes visible from Rome as well as from almost all other parts of the research area. A villa visibly part of a high society resort served the social and political aspirations of the owner. Being in the villa and views both internal and external created the sense of isolation and privacy. The area has a very dense road network ensuring good connectivity from almost anywhere in the region. The area of best visibility/viewability, dense settlement and most burials by roads coincide, creating a neighborhood for the area. When the various qualities are combined, the ideal locations featuring the most qualities cover nearly a quarter of the research area and more than half of all the settlement sites are located in them. The ideal location was based on centuries of practical experience and rationalized by the literary tradition. iii ... - tailieumienphi.vn
