MATERIAL CHARACTERIZATION OF GILDING AND PAINTING TECHNIQUES OF A POST-BYZANTINE ICON

This study aims to identify the materials used in the production of a post-byzantine icon from the Museum of Évora’s collection. The icon, representing the “Emperor Constantine and his mother Helen holding the Holy Cross” was once dated as being from the 10th century. Throughout a multi-analytical approach, combining area exams with spectroscopic techniques, this study tried to confirm its actual chronology. The results obtained revealed that it is most likely an icon from the late 17th or 18th century.

Europos. The Archaeology of the Heir of Karkemish During the Hellenistic, Roman and Byzantine Periods on the Basis of the Results of the British Museum and Turco-Italian Excavations

The present work aims at reconstructing the archaeological contexts and analyzing the material culture of the site of Europos. This archaeological site is located in southern Turkey, at the border with Syria, along the right shore of the Euphrates River. The Classical city rose above the remains of the Hittite Karkemish. The present work collects the results of the archaeological expeditions launched by the British Museum in the late 19th and early 20th century, never published, and the ones of the new Turco-Italian Joint Expedition, started in 2011. Europos had an uninterrupted life from the 3rd century BC to the 10th century AD, throughout the Hellenistic, Roman and Byzantine periods, all examined in the present work.

Nature in the books of seven metals – Ǧābirian corpus in dialogue with ancient Greek philosophy and Byzantine alchemy –

The Ǧābirian corpus was a receiver of ancient Greek ideas and, at the same time, a source of knowledge for the later Greek-speaking world, in particular for medieval Byzantine alchemy. Both aspects are explored in the dissertation with respect to the notion of nature. After a general introduction to the Corpus and the sciences described in it, particular attention is devoted to a Byzantine anonymous text, The Work of Four Elements, which was probably influenced by the Ǧābirian Books of Seventy. These texts exemplify how, in the theory of the Ǧābirian science, things are constructed from four natures (hot, cold, moist and dry), the balance of which defines what a thing is. By changing the balance of natures, one can transmute any metals into gold that is perfectly proportioned in terms of natures. Ǧābir presents the art of dyeing metals gold in the Books of Seven Metals which, along with chrysopoetic recipes, also include medical recipes and theoretical contents such as the theories of four humours, properties, and talismans. Moreover, Ǧābir postulated a substrate that does not change in itself and continues to exist when natures move in and out of things. Such primary existence is called the fifth nature as an additional principle to the four natures. This key concept for the Ǧābirian theory, which has been underexplored so far, is discussed through the textual and critical analysis of various unedited sources: the Books of Seven Metals and the Book of the Fifth Nature. This study confirms that the fifth nature was probably derived from ancient Greek philosophical concepts such as the Empedoclean particles, the Aristotelian fifth element and the Stoic pneuma. Thus, this research indicates the importance of the Ǧābirian corpus both in the history of alchemy and the history of philosophy.

Architecture and mosaics in recently discovered Palaeochristian basilicas

The excavations of the Dericik Early Christian Basilicas revealed the importance of the surrounding area of Bursa for understanding Early Christianity between the Late Roman and Early Byzantine periods. In the salvage excavations of 2001, the basic plan of the basilica (nave, narthex, presbyterium and apse) was revealed. The most important artefacts uncovered in that year were the mosaic pavements with geometric and plant ornaments and a grave located in the North Eastern corner of the church. The mosaic of the basilica was laid with the opus tessellatum technique on a thick mortar foundation with white, red, yellow, olive green and dark blue tesserae. A refrigerium scene is represented in the middle of the narthex mosaic. The mosaic in the centre of the nave is divided into parts, one of which with figures of birds inside octagons. In the transitional area between the nave and apse, three heavily damaged inscriptions have been conserved each of three or four lines, one of them indicating the wish of Epituchanos, diakôn, a church member.
