GP-NEP: a prototype of an assistant for non-experts in photogrammetric survey

Photogrammetry is a widely used survey technique for creating Digital Replicas, but its application requires some expertise in survey planning and execution that sometimes can represent a challenge, especially for non-expert users. This paper presents GP-NEP, a prototype tool designed to address this task. GP-NEP aims to guide non-expert users through the intricacies of photogrammetric surveying, helping to understand the key factors that influence the quality of the final Digital Replicas. By employing an interactive questionnaire-based approach, GP-NEP assists users in selecting suitable equipment and optimizing the survey process based on the complexity of the object being captured. The tool incorporates a complexity index assessment useful to evaluate the complexity of the object. At the end of the process GP-NEP generates customized reports, providing recommendations and insights. Through a comparative case study, concerning the 3D survey of two marble artifacts from the Roman river port of Seripola, it has been possible to test the effectiveness of GP-NEP.

Diagnostic study and efficiency evaluation of treatments against rising damp and salts crystallization in ornamental stones: the case of the green stone sacristy washbasin in the Church of San Domenico in Cosenza (Calabria, Italy)

The presence of water in masonry, especially in confined spaces, is one of the most important causes of deterioration of stone building materials. If water is present, particularly rising damp, degradation processes such as loss of surface material, encrustations, micro-cracks, salt efflorescences, etc., may arise and be intensified. Treatment against these phenomena is therefore strongly recommended for the protection and conservation of ornamental materials and buildings in general, before their restoration. In the present work, a multi-analytical approach was employed to study the stone materials and determine their state of conservation in the washbasin of the sacristy of the Church of San Domenico in Cosenza. The results allowed us to reveal details not visible to the naked eye that was important to conduct its conservation intervention. As for the state of conservation, the integrated use of various techniques enabled the detection of phenomena generally correlated with the occurrence of water infiltration and migration which appear to affect a large part of the area in which the asset is located, causing noticeable damage. Results concerning the cleaning, consolidating, and protective treatments on the artifact are also presented.

Isotopic analysis of black crust samples from the Monza Cathedral (Italy): a preliminary study

The degradation of historical buildings surfaces through the formation of black crusts is a process mainly related to air pollution. The origin of air pollutants can be determined by measuring the stable isotope ratio of their main elements. In this study, the results obtained from the isotopic analysis of BCs taken from the historical Monza cathedral, an important monument placed in Monza, a highly polluted city of Northen Italy, are discussed. In particular, stable isotope ratios of carbon, sulphur and oxygen of two black crust samples (namely MD and MS) were measured by Isotope Ratio Mass Spectroscopy. The obtained δ13C, δ34S and δ18O values suggest that anthropogenic pollution is responsible for the formation of black crusts on the façade of this cathedral.

First results of plant processing on ground stone tools: phytolith evidence and GC-MS from archaic Messapian settlements - San Vito dei Normanni and Cavallino (Puglia, Italy)

A large number of ground stone tools have been unearthed in the archaic Messapian settlements of San Vito dei Normanni - Castello d Alceste (Brindisi) and Cavallino (Lecce), in southern Puglia. The questions raised by these tools concern exploitation of food resources and distribution of productive activities within the settlements. First results of phytolith analyses conducted on ten grinding tools are presented. Quantitative and morphological analysis aimed at estimating the amount of phytoliths in the sediment, but also at identifying the types of plants used in the sites. Phytoliths indicated the nature of the vegetal processed matter, including cereals plants used for human and animal nutrition. Together with those from the analysis of organic residues already conducted at the sites these results contribute to the understanding of the food processing and dietary practices of the archaic Messapic populations.

The Via Severiana and its Representation in the Tabula Peutingeriana

We will examine the route of the Via Severiana, traced in the imperial period, from a historical and technical point of view. Later we will compare it with the Tabula, which we can consider one of the first synthetic representations of general viability.

Acoustic characteristics and defects of adhesion of ancient construction materials using the PICUS system

The text discusses the applications of the PICUS system in comparison to traditional auscultation techniques for analyzing detachments in historical and artistic artifacts. Non-Destructive Evaluation (NDE) techniques, although valuable for assessing the condition of materials and structures, face limitations in terms of feasibility, optimal operational conditions, and potential risks to delicate objects. In practical work environments, conservator-restorers often rely on traditional auscultation techniques, involving tapping the surface and observing vibrations, due to their accessibility, simplicity, and cost-effectiveness. These techniques provide immediate tactile feedback and insights into the condition and integrity of the artwork. However, they are subjective and rely on the expertise of the conservator-restorer. Overall, a combination of PICUS techniques and traditional auscultation can enhance the understanding of artifacts while considering practical constraints.

The Fathers' cell gardens of the Charterhouse of Calci-Pisa in Tuscany (Central Italy): pollen and multidisciplinary reconstruction

The archaeological investigation of the Charterhouse of Calci-Pisa (Central Italy) is a research project launched in 2018 by a multidisciplinary team of the University of Pisa. Three different monks gardens (the Prior s, the Apothecary s, and the Master s garden) have been investigated. The study focused not only on their structural transformations, evidenced by flowerbeds, pools, and fountains, but also paid special attention to pedological variations, plants diversity, and the presence of root systems, animals, and microorganisms, to detail changes in use, such as the succession of crops or fertilisation practices. Palynological and archaeobotanical results allowed us to reconstruct the succession of seasons in the gardens, with colourful and fragrant flowers, ornamental, aromatic, medicinal herbs, and fruit trees. The gardens seem to have a functional space organisation strictly related to the monks' peculiar kind of life, their personalities and feelings, and their relationship with nature and divinity.

Identification of plant elements represented in the suburban Villa della Piscina di Centocelle (Rome, Italy) as a source of reconstruction of the ancient gardens

Plants in art are not only decorative elements, they have symbolic values that cannot be neglected, because are bearer of a message, which need to be understood. Moreover, they usually show the connection with the surrounding natural landscape. Indeed, the phytoiconographic elements are important tools to reconstruct the lost garden. Our works aims identifying the plant representation to provide useful information for the reconstruction of the the ancient villa’s garden. We studied decorated wall remains and ceiling structures identifying the plant species and attributing their symbolic value and garden role. Preliminary data show the presence of more than twenty plants, mainly Mediterranean. The symbolic groups present a slight prevalence of solar and salvific elements. For the garden we identified species to decorate and border the flowerbeds, but also with productive role. The analysis of these represented naturalistic elements gives support in understanding the historical landscape behind their representation.

Preserving and valuing historic gardens: an analysis of projects under the Portugal 2020 investment framework (2014-2020)

Gardens are delicate and vulnerable assets. They are also cultural, artistic, and historical documents of great relevance that must be preserved and valued. Various funding programmes have sought directly or indirectly to help comply with this principle. The aim of this study is to analyse the conservation and enhancement interventions carried out in Portuguese historic gardens between 2014 and 2020, under the Portugal 2020 Community Support Framework. This is a funding programme for projects in various thematic areas. The public database containing all approved applications was therefore analysed. Twentyfour projects involving 20 historic gardens were identified. This is a relatively small number of projects considering how many historic gardens there are in Portugal. Most of the approved projects are located throughout the North and Centre regions, and the interventions mainly focused on the physical rehabilitation of the spaces and their elements. Some suggestions are presented to enable these funds to be more widely used in Portuguese historic gardens.

Garden heritage and tourism: present and future of Madeira Island as a garden destination

Madeira Island (Portugal) is widely recognized for the exuberance of its landscape, largely anchored in the abundance of gardens, parks, and flowers. These are one of the biggest tourist attractions, as well as one of the great brand images of this region, which has helped to position the island on the route of a worldwide interest in visiting gardens. Garden tourism has therefore gained expression. This work aims to analyse the trajectory of the garden tourism in this destination by evaluating the supply and demand trends in the three main entrance-fee gardens. It goes beyond the strategies implemented and looks at the constraints that remain, the associated challenges and potentialities, finishing with suggestions to improve the garden experience in Madeira. It is a fact that tourism has acted as a vehicle for validating this heritage. The island has a huge range of spaces capable of positioning it as an outstanding garden destination. The demand for gardens has increased, although it is still firmly based on the three anchor-gardens. Improvements in maintenance and available information are highlighted, but Madeira s garden tourism lacks a strategic and comprehensive vision of its multiple actors and interests.
