These techniques enabled them to determine the elemental and mineralogical composition of the tesserae, effectively fingerprinting the materials used.

  Their findings reveal a diverse palette of geological materials sourced from a surprisingly wide geographical range. The study identified various types of limestone, including Egyptian calcite alabaster, which contributes to the mosaic's luminous white hues, and a distinctive gray limestone possibly originating from the Hymettus region near Athens. Furthermore, the analysis confirmed the presence of volcanic glass, specifically obsidian, sourced from the Aegean island of Melos, used for black tesserae. The vibrant red and yellow hues were traced back to terracotta-like materials, likely fabricated locally using clay mixed with specific pigments like hematite or ochre.

  The authors highlight the significant implications of these discoveries. The utilization of materials from distant locations, such as Egypt and Melos, underscores the extensive trade networks and economic interconnectedness of the Hellenistic world. It also speaks to the considerable resources invested in the creation of such prestigious artworks. Furthermore, the identification of specific geological sources offers valuable insights into the artistic choices and technical skills of the mosaicists. The careful selection and combination of different stone types allowed them to achieve a rich chromatic range and create a remarkably lifelike representation of the historical battle scene.

  Beyond its contribution to art history and archaeology, the study demonstrates the potential of applying advanced analytical techniques to investigate ancient artifacts. By examining the geological composition of the mosaic's tesserae, the researchers have unearthed valuable information about ancient material sourcing, trade routes, and artistic practices, offering a more comprehensive understanding of the cultural and economic contexts in which this iconic artwork was created. This interdisciplinary approach paves the way for future studies of ancient mosaics and other artifacts, furthering our appreciation of the sophisticated craftsmanship and global connections of the past.
