heal.abstract	Analytical examination of ancient artefacts is a key component of archaeological research; it can shed light to the ingredients and technologies commonly used in antiquity, or even reveal information about technological exchanges and trade. Τhe Royal Tombs discovered at Aigai (modern Vergina), the necropolis of ancient Macedonians, during the 1970s and 80s by the Greek archaeologist Manolis Andronikos, are extraordinary monuments both to the history and the arts and crafts of ancient Greece. In the main chamber of the so-called “Tomb of Queen Eurydice” an unprecedented monumental marble throne preserves on its back a painted panel depicting Hades and Persephone on their divine quadriga, rendered with costly pigments and gilded decoration. Analytical studies on materials and techniques of application were carried out by handheld X-ray Fluorescence (HHXRF) spectrometry. The analysis of the marble throne of so-called “Tomb of Queen Eurydice” successfully identified the presence of more than eight different pigments, including a variety of iron-based ochres, Egyptian blue, lead white and cinnabar. Moreover, HHXRF analysis aided with Monte Carlo simulations confirmed that gold leafs of few micrometers were superimposed on polychrome layers. The application of in-situ, non-destructive Macroscopic XRF (MA-XRF) imaging analysis emerged as the most suitable method of identifying the original gamut of pigments and re-visualizing the remaining traces of polychrome on Early Cycladic II (2600-2300 BC) figurines and vessels. The in-situ measurements were carried out at the National Archaeological Museum and the Museum of Cycladic Art in the framework of the multidisciplinary project ‘The Technology of Early Cycladic Marble’, using the novel LANDIS-X spectrometer. Twelve figurines and three vessels were examined, in total. The MA-XRF imaging of the artefacts surface (~cm2) revealed clear evidences of the use of specific pigments, but also traces of other, non-correlated with pigments, materials.	el
