The antiquary Sir William Gell (1777–1836) was most famous for his two books on the archaeological discoveries at Pompeii (also reissued in this series) but his interest in the topography of classical sites resulted in several other publications, including this two-volume work, first published in 1834. The work was intended to accompany a map (available to download at http://www.cambridge.org/9781108042109) of the territory of ancient Rome, for which the field research and surveying activities were carried out in 1822. It provides alphabetical entries (from Abbatone to Zagarolo) on all the sites in Rome and its environs, with their modern names and populations, and their significance in ancient history and literature. Volume 2 also contains essays on the history and languages of ancient Italy, and supplements to various entries, where new discoveries had been made during the course of the work's preparation.
