Lighthouse Mosaic

This mosaic (c. 3rd c. AD) from Statio (commercial office) 46 in Ostia’s Piazzale delle Corporazioni depicts a four-tiered lighthouse flanked by two ships—one with a round hull, the other with a ram—and a dolphin below. Likely representing a harbor guild, it underscores navigation, protection, and Ostia’s crucial role in directing maritime commerce safely to Rome.
