This thesis focuses on the detection of marble sculpture forgery made of cultured marble. Cultured marble is a mixture of marble dust, polyester and accelerators. Thus chemical analysis of cultured marble would give declined levels of calcium when compared to authentic sculptures. Since sample removal is a problem when dealing with archaeological heritage, the instrument used was portable X-Ray Fluorescence device which provides in situ analysis of the samples. Device has been used to analyze six authentic and four forgery sculptures. Seven of the sculptures were provided by Anatolian Civilizations Museum and three of them were provided by a sculpture workshop, AkĢit Sanat. In the assessment of the results the software SPSS has been used. The results support the idea of lower levels of calcium in forgeries. Also cobalt and lead elements show distributional differences between authentic sculptures and forgeries. Further studies with a larger sample size is needed. However, the technique proves to be useful in distinguishing cultured marble sculptures from authentic marble sculptures.

Improved methodology for identification of Goktepe white marble and the understanding of its use: A comparison with Carrara marble
Wielgosz-Rondolino, Dagmara; Antonelli, Fabrizio; Bojanowski, Maciej J.; Gladki, Marcin; Göncüoğlu, Mehmet Cemal; Lazzarini, Lorenzo (2020-01-01)
The provenance of marbles used for ancient statuary and architecture is of utmost importance for archaeologists, art historians and archaeometrists. The aim of this paper is to provide a comprehensive characterisation of the white marble exploited in antiquity in Goktepe (Mugla Province, Turkey) to increase the reliability for identifying this marble in ancient artefacts. A campaign of interdisciplinary archaeological and geological fieldwork undertaken by the Marmora Asiatica project is based on a multi-me...
Archaeometric analyses of mural paintings from ancient Side (Antalya) theatre gallery M
Kaymaz, Saadet; Atalay, Mustafa Ümit.; Department of Archaeometry (2019)
In this study material of wall paintings were analyzed to determine the structure of plasters, mortars, and pigments of Side wall painting samples. Archaeometrical methods were used to investigate mineralogical and chemical compositions and raw material characterization. Binder-aggregate ratio and particle size distribution analysis, gravimetric analysis, petrographical thin section optical microscopy analysis, Raman Spectrometry, XRD, PED-XRF, SEM-EDX techniques and methods were used to examine the samples...
Archaeometric investigations of glass from the early Byzantine workshop in Side, Antalya
Genç, Deniz; Atalay, M. Ümit.; Department of Archaeometry (2019)
Reconstructing the history of archeological artifacts leads us to examine the materials using various scientific methods. Therefore, archaeometric investigations allow us to understand the production technology, the firing temperature, provenance, the raw materials and the colorants used in the process. This thesis aims to investigate the archaeological glasses found at the Side excavation site. Visual and optical microscope analyses were conducted to observe the physical shape, deterioration types, and the...
Changing context of Olympic victor statues in Greece and Rome
Köseoğlu, Ayça; Güven, Suna Naziyet; Department of History of Architecture (2012)
The aim of the thesis is to investigate the standing of Olympic victor statues in Greece and Rome. The major focus is on how the meaning and the perception of the statues become transformed in different contexts. Throughout the study the reception alongside the location and meaning of athletic sculpture are primary points of concern. The standing of the patron and the viewer with respect to transformed models and their perception in relation to context constitute a significant part while formal details of a...
Building System Characterization of Traditional Architecture in Cappadocia, Turkey
ŞAKAR, FUNDA SOLMAZ; Şahin Güçhan, Neriman (2018-01-01)
Located in central Anatolia, Cappadocia presents a spectacular landscape created by characteristic geology and architectural patterns. Throughout the region an indigenous settlement pattern has been generated by using rock carving and masonry techniques. This article aims to identify and characterize the building system specific to this region and to analyze it through a systematic study. For this analysis more than twenty representative examples of traditional houses from Urgup and the nearby villages of M...
