I bought, and years later sold, coins of Ptolemy I Soter. Ptolemy was a general of Alexander the Great. After Alexander’s death he ruled Egypt as satrap and pharaoh. He also built the world’s first lighthouse, the Pharos of Alexandria, a Wonder of the World and a model for all lighthouses thereafter. Our new wing of Mona is a lighthouse too, but not one designed to warn ships of the risk of foundering on rocks. Our lighthouse is a testimonial to the power of light as art—not just as a medium for artworks, but as an object.
