Pierotti, Ermete was an Italian engineer and archaeologist. Details of his life are limited in publicly available sources, and neither his dates of birth and death nor his educational background are clearly recorded. What can be confirmed is that he wrote Jerusalem Explored, a work in two volumes: Volume 1 is the text volume and Volume 2 the plates volume. The book examines the remains and topography of Jerusalem and the Holy Land, combining engineering surveys with archaeological observation and presenting the region's historical relics and landforms through written description accompanied by plates. In style, Pierotti emphasizes fieldwork and empirical recording, focusing on specific monuments and topographical analysis rather than general discussion. The two-volume structure allows the text and images to be read against each other, helping readers understand the spatial layout and condition of the holy sites. The work remains a reference for the archaeology and topography of nineteenth-century Jerusalem and retains some value as a historical source.
