Article Citation - Scopus: 1Characteristics and Production Technologies of Byzantine Building Bricks From the Anaia Church in Western Anatolia(Springer, 2023) Çam, Elif; Uğurlu Sağın, ElifFired bricks were valued as essential building materials in the central tradition of Byzantine architecture in Constantinople (Istanbul), Anatolia, and the Balkans. In this study, Byzantine bricks from three construction periods, covering nearly nine centuries (fifth-fourteenth centuries), of Anaia Church (Kadikalesi) in Western Anatolia were investigated to determine their characteristics, raw material properties, and production technologies. The characteristics of the bricks were evaluated and compared in order to identify similarities and differences between the periods and to investigate the continuity of the tradition of brick production over centuries. Basic physical and colorimetric properties, chemical and mineralogical compositions, thermal behavior, and microstructural and mechanical properties of bricks were determined by scanning electron microscopy (SEM) coupled with energy dispersive spectroscopy (SEM-EDS), Fourier-transform infrared spectrometry (FTIR), X-ray diffraction (XRD), thermogravimetric analysis (TGA), and mechanical tests. The results indicated that all the bricks in the Anaia Church were brown-beige colored, highly porous, low-density materials with low mechanical strength. They were produced from Ca-rich clays, probably obtained from two different sources used during all construction periods. The mineralogical composition and thermal properties revealed that the bricks from the first and second periods were fired at between 800 and 900 & DEG;C and the bricks from the third period were fired at < 850 & DEG;C. Greater calcium content and firing temperatures were found to reduce the total porosity and the number of small pores (< 10 & mu;m) and increase the mechanical strength of the bricks. The results of the study revealed no significant differences in the production of bricks, including raw material sources and kiln conditions, for the different construction periods of the church.Article Citation - WoS: 5Citation - Scopus: 6Revisiting the Conditions of Authenticity for Built Heritage in Areas of Conflict(Mdpi, 2021) Saifi, Yara; Yüceer, Hulya; Hurol, YoncaThis article examines the application of conditions of authenticity within the context of built heritage management in areas of political conflict, where heritage management can be seen as a political act rather than a means of protection. It focuses on values attributed to built heritage that can be targeted or reinvented by the dominant power in areas of conflict with minorities being powerless to intervene. The argument is built around the Agios Synesios Church in North Cyprus, which continued to be used by the Greek Cypriot minority following the island division in 1974. Although their way of life has been compromised, they have embraced forced change through using the church to maintain their ritual and religious practices; by doing so, they negotiate their values towards their heritage. In this case, the study shows that the conditions of authenticity are difficult to meet, given the means through which heritage management can be manipulated. Accordingly, the article aims to contribute to general discussions on the vagueness and enigmatic conditions of authenticity in areas of conflict. Different buildings in areas of conflict around the world suffer because of the political nature of heritage management, which makes the criteria of authenticity unviable.
