This folio architectural engraving is from Antoine Babuty Desgodetz work The Ancient Buildings of Rome or Les edifices antiques de Rome. The work was published by George Marshall in 1771. It is the first English edition of the first accurate representation of ancient Roman architecture.
Desgodetz work was extremely detailed and highly decorative. He was sent to Rome to create engravings of the monuments and antiquities to further instruct French artists and architects.
