Construction details and an inscription found in the Farnese Gardens 

This etching by Italian artist Giovanni Battista Piranesi (1720-1778) is a detailed plan of architectural elements, including roof designs and decorative elements, which were found in the Farnese Gardens. The plan also includes inscriptions in Latin, and a view of a Roman structure, which may have been reconstructed by Piranesi, who was known for his meticulous reconstructions of Roman ruins. The etching is a testament to Piranesi's fascination with Roman architecture and his skill in reproducing it in great detail.
