Revealing the unseen: Technical digital imaging and art characterization for the study of Cypriot composite icons, 2023

different times, one inserted into the other. Icons of this unusual type, first described by
Panayotis L. Vocotopoulos, are quite numerous on Cyprus and date mostly to the 16th century.
This study focuses on one example that is still venerated at the Church of Saint Nicholas in
Palodeia. The main aim of the case study introduced in this paper was to expand knowledge on
existing methods in conservation and art history for the study of composite icons. This was
done by integrating digital imaging techniques along with non-invasive material analysis
conducted by the research group at the Andreas Pittas Art Characterization laboratories (APAC
labs) of the Cyprus Institute.

“The Digital Aposphragisma Project, New Methods and Approaches to the Digitization of Ecclesiastical Cultural Heritage of Cyprus and Crete”, 2020

An interregional collaboration project supported by the INTERREG-VA 2014-2020 Cyprus-Greece.
The project involves documenting a wide variety of ecclesiastical cultural artefacts from paintings to liturgical objects and monuments spanning almost 1000 years of history (Byzantine, Medieval, Ottoman and Modern period). Cultural heritage of different size, material and provenance, this pilot project will bring forward a methodological approach into the multi-level documentation of such objects and monuments. In parallel this project is initiating a new challenge, which lies in between two-dimensional (2D) and three-dimensional (3D) image and sensor-based technologies for the documentation and visualization of ecclesiastical culture heritage.

The work followed several steps: the identification of the significant potsherds for the 3D reconstruction, the 3D acquisition of the fragments with laser scanner, the analysis of the 3D models (diameter, vertical projection, orientation, thickness), 3D reconstruction and modeling of the vessel, photographic acquisition and ortho-stereoscopic rendering for 3D visualization. The obtained 3D model was verified validated by the archaeologist.

This paper uses as its foundation the London Charter's principles , which provides guidelines for 3D visualization of these type of data, and describes how these principles can be implemented on a Cultural Heritage 3D reconstruction process, in this case, the Hellenistic-Roman theatre of Paphos.

Stereoscopy or stereo-scopic imagery is the technique for recording three-dimensional visual information by using the characteristics of human binocular vision to recreate the illusion of depth of a digital image as of the real world. The technique relies on presenting two slightly different images on to the retinas of our eyes, which the brain's visual cortex automatically blends into a single view or a spatial representation. Subtle right-left dissimilarities in the images create the perception of depth and can be manipulated to creative advantage. Illusionary depth perception accommodates solidity that creates immersion and realization of objects in the Cartesian space, therein lies the stereoscopic virtual reality for archaeology.

Dendrochronological (tree-ring dating) analysis offers the opportunity to study the timing and origin of timber exploitation with almost unmatched precision, and provides a biological archive of past climate and environment. Yet, despite multiple studies on modern trees and forest ecology in Cyprus, almost no dendrochronological research has been conducted on the island’s numerous historical and archaeological wood materials. In response the Cornell Tree-Ring Laboratory has initiated the sampling and analysis of wood from multiple historical and archaeological sites on Cyprus, including a series of villages abandoned during Cypriot Greek-Turkish inter-communal strife and resettlement during the 1960s-70s. An important aspect of this research includes determining the source of timbers using dendrochronological methods (‘dendroprovenancing’), in order to gain further information on long-term use of trees from different ecological zones and of local or imported forest resources. We concentrate here on the results of dendrochronological study of two historical villages, Ayios Sozomenos and Phinikas, which show an increase of building activity in the late 19th century-early 20th century, using local pine timber resources, and subsequent repairs to buildings throughout the 20th century, which eventually favored imported northern European timber. Ongoing work in interviewing former village inhabitants and detailed mapping and image analysis of the buildings allow further important insights into the recent, largely forgotten history of these settlements prior to their mid-20th century abandonment, as well as the environmental history of Cyprus.

The platform provides an innovative merge of digital imaging and data management systems that offer great new opportunities for research and the dissemination of numismatic knowledge online. A unique feature of the platform is the application of Reflectance Transformation Imaging (RTI), a computational photographic method that offers tremendous image analysis and possibilities for numismatic research. This computational photography technique allows the user to observe on browser minor details, unseen with the naked eye just by holding the computer mouse rather than the actual object. The first successful implementation of OpeNumisma has been the creation of a digital library for the medieval coins from the collection of the Bank of Cyprus Cultural Foundation.
