    The existence of Bronze Age settlements, in the Lisbon region, is well attested by its
    material culture, in terms of ceramics, metals and flint, which can be verified by archaeology, through archaeological surveys developed since the early 1970s by the
    archaeologists Gustavo Marques and Miguéis Andrade, who left us an exhaustive national survey that was published in the annals of the III National Congress of Archaeology, held in Porto, in 1973.
    The study carried out on the denticulate was aimed at the origin of the stone, regional
    or otherwise, in order to confirm if there was a workshop for the carving of these pieces
    or if, on the contrary, it was exclusively handmade production, according to the needs
    of each couple or village.
    Keywords: Late Bronze Age, Lisbon Region, Denticulate, Flint and Agricultural tools.

    In 2015, during an archaeological intervention made by the team from the Lisbon’s Archaeological Center (CAL), a sig- nificant group of stone materials was collected at the Rua da Conceição, no 75-77, in Lisbon. This set of materials is of great interest not only for a typological and functional analysis but also for a lithological study.
    From the observation of the various stone materials it was possible to outline a fairly comprehensive work method in order to settle a typology for the pieces, suggest their possible functionalities and categorize the type of stone used regarding the building, the covering of pavements and walls and the architectural decoration of structures related to the Cryptoporticus of Roman Lisbon.
    This methodological approach involves a conceptual reflection on the role of the covering and architectural decoration in the Roman world, a final stage in the building theory according to Vitruuius.
    The initial informations we aim to introduce are a first step in a work in progress designed to be organized and disputed, adjustable and through, accounted for and comparative, continuously reviewed and assessed evaluated. To extract and to produce are long-lasting, complex and challenging tasks in the Roman world.

    Flint mining during the Neolithic and the Chalcolithic was a recurring aspect of European Prehistory, either through underground galleries or through the exploitation of open shafts of this sedimentary rock. Several sites are known in Europe where flint extraction has been carried out. In the century XIX, works coordinated by Paul Choffat, during the widening of the Rossio railway tunnel in Campolide, two flint mining galleries were discovered. A survey carried out on the collections of the Geological Museum, and other archives, al‑ lowed a better understanding of what was discovered in 1888, comparing the Portuguese case with others of similar period and similarity at European level, as well as the petrographic analysis of the various lithic ele‑ ments in deposit in that museum.

    The archaeological studies of Prehistory in Lisbon have an old tradition counting on more than century and a half, dealing in particular with the artefactual side.
    We present a proposal for a study of human occupation of the present territory of Lisbon during the Late Periods of Prehistory (Late Neolithic, Early Chalcolithic), suggesting the reconstruction of a possible landscape that has long disappeared. The knowledge we have about the period we are now studying comes from scattered data, which globally observed allows us to construct an image of a certain pattern of occupation.
    Thus, through spatial analysis of the geographical area in question, we tried to define hypothetical exploration territories by means of calculations carried out in all directions, joining the points together to close the territory of each site, based on the determinative method of its area of and the time needed to travel the distance from the village to the fields of agriculture, pasture and lithic resources.
    Benefiting from a temperate Atlantic climate and a geology that provided ample lithic resources (geological nucleus such as the Bica Formation, dating from the Upper Cenomanian, it presents sequencing of crystalline limestone’s with abundant flint nodules of different dimensions and aspect), its exploitation took place over a long time span.
    Inherent in the human being, building "mind maps" in a way to rationalize and apprehend the surrounding landscape of our field of vision fundamental to the perception of the occupation of a space. The various charts of soil capacity, the observation of the orography and the implantation of the area of agricultural exploration, through the time necessary to cover a certain distance, allow us to present some data referring to the different types of territorial occupation, its implantation in the landscape and the demographic dispersion of the prehistoric populations of the region concerned.
