Archaeologists Discover Subtle Indications Within the Alexander Mosaic, With Its 2 Million Miniscule Stones Originating from Unexplored Regions of the Ancient Realm
In the heart of Pompeii, a significant Roman-era mosaic, known as the Alexander Mosaic, continues to captivate historians and archaeologists. This masterpiece, unearthed in 1831 at the House of the Faun, depicts Alexander the Great's victory over Persian king Darius III at the Battle of Issus in 333 B.C.
Recent research has shed new light on the mosaic's composition, revealing that the over two million tiny tesserae were sourced from quarries across Italy, Greece, Tunisia, and the Iberian Peninsula. This wide distribution of materials indicates not only the mosaic’s high value and the resources invested in its creation but also reflects the interconnectedness of these ancient regions through commerce and artistic influence.
Researchers classified the tesserae into four groups based on their composition, providing insights into their distinct geological origins. White tesserae may have originated from Italy's Apuan Alps, while green tesserae hint at serpentinites or other stones sourced from Roman-era quarries across the empire. These insights will go a long way in improving ongoing conservation strategies for the mosaic.
The findings regarding the Alexander Mosaic were published in the journal PLOS ONE. This discovery also helps historians and archaeologists better understand the mosaic’s artistic and technical development, linking it to Greek mosaic traditions and showing how these techniques were adapted and enhanced in Roman art.
In a recent restoration initiative, researchers used non-invasive technologies like portable X-ray fluorescence (pXRF), infrared thermography (IRT), multispectral imaging, Raman spectroscopy, and Fourier-transform infrared (FTIR) spectroscopy to study the mosaic without disturbing it. Past restorations left protective wax coatings and gypsum layers on the mosaic during its 19th-century transport to the National Archaeological Museum of Naples. Infrared thermography was used to pinpoint areas where tesserae had shifted due to environmental stresses in the mosaic.
The Alexander Mosaic serves as a visual and historical document, illustrating ancient artistic networks, economic trade routes, and cultural synthesis spanning multiple civilizations. It enriches our appreciation of the mosaic’s provenance and the complexity behind Roman-era artworks found in Pompeii. By gaining control of key coastal cities along the Mediterranean coast, Alexander cut off Persian naval power and ensured his supply lines were secure for future campaigns, further emphasizing the mosaic's historical significance.
