This article reports on the results of a research project entitled 'KARAVOI. The Ship Graffiti on the Medieval Monuments of Cyprus: Mapping, Documentation and Digitisation', during which 233 ship graffiti were recorded in 44 different monuments on the island, dating from the 15th to the 20th centuries. Innovative recording techniques have been used to mitigate the effects of the subjective or partial recording of graffiti lines on tracing paper. Apart from the study of ship graffiti as iconographic sources, particular emphasis has been given to their geographical and social context through a comprehensive analysis of the graffiti types and their spatial distribution in the monuments as well as the monuments location on the island.
ABSTRACT:The World Heritage Convention, drawn by various international bodies in 1972, was designed to protect cultural or natural places of outstanding universal value so that future generations may be able to enjoy them. Responding to these principles as well as to the Charter on the Preservation of Digital heritage (Vancouver, 2003), this multidisciplinary project, which involves archaeologists, art historians, conservators and computer scientists, aims to create an open access, 3D interactive online geo-database of endangered architectural and archaeological heritage in the South Eastern Mediterranean basin; a region of tremendous cultural importance whose rech heritage is unfortunately threatened by both natural and human factors. A wide range of 3D modelling and topographic techniques have been applied to create accurate reconstructions of heritage sites, enriched by a extensive array of metadata.
The present study illustrates the results of an interdisciplinary collaboration between the Mediterranean Laboratory of Survey and Diagnostics for Architecture (RDA) of the Department of Civil Engineering and Architecture (DICAR) of the University of Catania in Italy and the Andreas Pittas Laboratories for Art Characterisation (APAC) of the Science and Technology in Archaeology Research Center (STARC) of the Cyprus Institute in Cyprus. The research focused on the application of an H-BIM approach in the study of a Mediterranean iconic heritage asset, the St. John Cathedral of Nicosia, built in 1662 on the remains of a monastery from the 15 th century. The adopted methodology has provided the framework for a dynamic investigation, constantly evolving along several dimensions: historical, geometric spatial, architectural-constructive identification and mapping of degrade, interpretation of degenerative causes and design proposals.
The present study discusses new research on the analysis of a portrait of a male figure discovered under the painting of Ecce Homo, attributed to the studio of Titian (ca. 1488Titian (ca. -1576, with an estimated date in the 1550s. The portrait was examined with non-invasive methods: X-ray radiography (XRR), digital microscopy and micro-XRF. The examination of XRR images exposed the details of the painting's underlying depiction, which according to the details preserved appears to be a completed or nearly finished portrait of a standing man. The application of digital microscopy on the Ecce Homo painting's cracks enabled the identification of the work's stratigraphy. Micro-XRF performed on selected spots allowed to identify lead white, vermilion, red iron oxide, umber, carbon black and copper green in the underlying portrait. The described investigation methodology was guided by the close visual analysis of the Ecce Homo work and proved to be effective in the identification of the pigments of the hidden painting and the reconstruction of its colour palette.
A challenging aspect of visibility studies is visual acuity, which concerns the clarity of vision within a given space in relation to variables such as spatial geometry, lighting conditions, the physical properties of the viewed object, or the familiarity of viewers with the target. Our research proposes a novel approach to visibility studies, based on visual acuity and its related pipeline, which integrates qualitative and quantitative aspects such as the cultural background of viewers, the illumination values of space, contrast, and size of objects of interest as well as their meaning and context. The proposed pipeline relies on 3D documentation of the investigated space, light measurements, research in optics, trigonometry calculations, and 3D GIS set against images and architectural space. The method's effectiveness is demonstrated in the study of the iconography of the Cathedral of St. John the Theologian in Nicosia, Cyprus, the work hypothesis being that the church's spatial organization, choice of scenes, and level of detail were carefully planned to establish visual narratives with strong political and religious connotations and to overall dictate the ways the building was accessed and experienced. The method can be broadly applied for visibility analyses in a variety of case-studies in closed spaces.
