The Valley of the Anio, with the Upper and Lower Cascatelle, Mecenas's Villa, and Distant Campagna

Robert Macpherson was a British photographer and antiquarian active in mid-19th-century Rome, where he documented classical sites and Renaissance architecture with large-format paper negatives. Working primarily in albumen print, he produced systematic photographic surveys of Italian cultural patrimony that established him as a pioneering figure in archaeological photography. His archive remains a significant record of Roman monuments and artworks as they existed in the 1850s and 1860s.
