A Topographical Dictionary of Ancient Rome

This useful topographical dictionary was compiled by Samuel Ball Platner (1863–1921) of Western Reserve University in collaboration with Thomas Ashby (1874–1931), the third director of the British School of Archaeology at Rome.

Sadly, Platner died before the work was completed, and Ashby eventually published it in 1929. The bulk of the work is an alphabetical list of the buildings, streets and geographical features in ancient Rome mentioned by ancient authors and/or discovered by more recent exploration and excavation of the ruins, with details about literary and historical references, and about the original and any surviving structure.
