This etching by Giovanni Battista Piranesi is a detailed plan of the factories that existed at the Villa Adriana, a large Roman imperial villa built by the Roman emperor Hadrian. The plan is a precise and intricate map of the grounds, depicting the layout of the buildings and surrounding landscape. Piranesi's masterful use of line and shading creates a sense of depth and realism, highlighting the architectural grandeur of the villa complex. The dedication to St. M Stanislaus Augustus, King of Poland, suggests a possible connection between the artist and the Polish royal family.
