The Alexander Mosaic, a Roman-era mosaic, is a faithful copy of a lost painting by Apelles, a renowned painter of Ancient Greece.

The mosaic showcases the dynamic energy of a clash between Alexander and Darius III, highlighting the importance of this historical event. The realism and detail of the mosaic suggest the influence of Apelles, known for his mastery of light and shadow, and his focus on realistic depictions of human figures. Despite its unknown original location, the Alexander Mosaic is a testament to the enduring legacy of both Apelles and Alexander the Great.
