Methodological advances in polychromy research
This study presents a comprehensive, non-invasive investigation of the polychromy onsculptural fragments from the West Pediment of the Archaic Temple of Apollo atDelphi. Utilizing a multimodal analytical framework, comprising macroscopic X-rayfluorescence (MA-XRF), Raman spectroscopy, hyperspectral imaging (HSI), andremote spectral imaging (RSI), the research identifies a sophisticated palette includingcinnabar, Egyptian blue, hematite, goethite,…
A Multi-Analytical Approach for the Investigation of Black Crusts on Two Monuments in Athens, Greece
Analytical studies of archeological materials often face challenges, such as the merging of heterogeneous, multidimensional datasets from complementary analytical techniques, and incorporating site- and user-defined parameters. In this study, a data fusion methodology is applied that combines micro-X-ray fluorescence (micro-XRF) spectrometry and handheld Raman spectroscopy to investigate degradation layers and identify pollution sources on two mo…
Mycenaean Vitreous Artifacts
Mycenaean glass artifacts, such as beads and relief plaques, are highly susceptible to degradation, which can significantly modify their visual attributes and pose classification challenges. Corrosion on glass and faience artifacts has often led to misinterpretation, since the visual manifestations of degradation can be similar for both materials, impacting research conclusions. This paper presents a segment of a broader study conducted within th…
Determining the Thickness of Gold Leaf in Post-Byzantine Religious Panel Paintings Using Imaging μ-XRF
Thin gold leaves were frequently used to embellish post-Byzantine religious panel paintings. Measuring their thickness using non-destructive methods is essential for understanding the technology behind their creation and developing effective preservation strategies. This study describes a method for non-invasively measuring the thickness of these gildings using large-scale imaging micro-X-ray fluorescence (μ-XRF) spectroscopy. The method relates …

Investigating the Degradation of Mycenaean Glass Artifacts Using Scientific Methods
Mycenaean vitreous artifacts, such as beads and relief plaques, are highly susceptible to degradation, which can significantly alter their visual characteristics and pose challenges to their taxonomy. The visual manifestation of corrosion on vitreous artifacts, especially glass and faience, has often led to their misclassification, which, in turn, has a significant impact on their interpretation by researchers, often resulting in misleading notio…
What jewelry did people wear in the Middle Byzantine period (10th-12th C. CE) in the Peloponnese? A technological and analytical case study
Analysis of Middle-Byzantine copper-based jewelry from Ancient Pallantion. • Identification of manufacturing techniques of wires. • Intricate decorative elements on earrings highlighting the expertise of the jewelers of the Middle Byzantine period. • Presence of Ni, As and Pb in the alloy as a deliberate attempt to lower the cost of raw materials and imitate silver jewelry. The present paper presents the preliminary results of the archaeometric a…
Chemical analysis of bronze votives from the Minoan peak sanctuary at Ayios Yeoryios Sto Vouno, Kythera
Analytical exploration of the Mycenaean glass world via micro-Pixe
During the Late Bronze Age, the Peloponnese with its palatial centers becomes the heartland of the Mycenaean world, resulting in an idiosyncratic material culture within the archaeological record, with glass constituting undoubtedly an important agent gaining prominence from the 15th cent. BC onwards, at the time when the palaces start rising and turning out to be characteristic to the Mycenaean material culture of the palatial elite. In this pap…
Microscopic X-ray fluorescence analyses (μ-XRF) of copper-based and silver alloy coins minted in Rhodes, Greece, from the fourth century BCE to the second century CE
The present study provides new data from the analysis of 111 copper-based and 11 silver-alloy coins from the ancient city of Rhodes, Greece. This is the first time that an elemental analysis has been carried out on copper-based coins issued by the Rhodian mint from the mid-4th c. BCE to the 2nd c. CE. Based on the μ-XRF results, three different groups of copper-based alloys are formed, with tin and lead as their major alloying components. The ele…
Characterization of black crust on archaeological marble from the Library of Hadrian in Athens and inferences about contributing pollution sources
Samples of black crust from the Roman-era monument of the Library of Hadrian (Athens) have been collected to perform chemical and mineralogical characterization of the degradation products on built heritage, utilizing a synergy of analytical techniques. The decay features consist of typical black crusts and a Fe-rich aluminosilicate patina. The chemical composition of the crusts, the element distribution along the crust and the characterization o…
Bronze votive pins from the sanctuary of Athena Alea at Tegea, Arcadia, Greece, ca. 9th-7th BCE
Macroscopic XRF imaging in unravelling polychromy on Mycenaean wall-paintings from the Palace of Nestor at Pylos
Micro‐XRF analysis of silver decorations on Archaic helmets from Olympia
Quantitative micro‐X‐ray fluorescence (XRF) analyses were performed on 19 silver decorations of six Archaic bronze helmets from the archaeological site of Olympia, Greece. The principal aim of the study was to investigate technological aspects of the smelting process that influence the composition of Ag, reveal possible elemental correlations and shed light on its source, assigning a likely provenance. The XRF results revealed that all decoration…
Characterization and provenance of ceramic artifacts and local clays from Late Mycenaean Kastrouli (Greece) by means of p-XRF screening and statistical analysis
The “lost art” of Archaic Greek painting
In the present work, four wooden panels dated to the second half of the 6th century B.C., discovered in 1934 inside a cave located in Corinthia near the ancient city of Sicyon, are examined. The “Pitsa pinakes” are the oldest known examples of panel painting in ancient Greece. The application of non-invasive and non-contact imaging and analytical techniques (imaging techniques, including infrared-reflected and visible-induced luminescence, micros…
The Height of Denier Tournois Minting in Greece (1289–1313) According to New Archaeometric Data
The years 1289–1313 witnessed particularly prolific minting activities at different southern and central Greek mints on behalf of different polities. The coin issues are of great economic and political relevance, and therefore of interest to modern historians. Our understanding of these is based on traditional sources, either numismatic (types and finds), or historical. This paper aims to investigate the possibilities of adding further details to…
Combined in situ micro-XRF, Libs and SEM-EDS analysis of base metal and corrosion products for Islamic copper alloyed artefacts from Umm Qais museum, Jordan
New evidence for the use of cinnabar as a colouring pigment in the Vinča culture

A smiting-god-figurine found in the Sanctuary of Poseidon at Kalaureia
In 2007 a Reshef figurine was found in a secondary context southeast of the Temple of Poseidon at Kalaureia. This article discusses its origin in the Syro-Palestinian area in the thirteenth century BC and suggests it arrived at Kalaureia towards the end of the Late Bronze Age and was deposited in a sacral context. As Reshef in later history was identified with Apollo in the Greek environment, the author speculates on there being perhaps a kernel …
