The Corpus Inscriptionum Latinarum (CIL) was a collection of inscriptions from across the Roman Empire. Launched in 1853 by Theodor Mommsen, the project was backed by the Berlin Academy. The corpus was eventually published in 16 parts, each divided into several volumes, as a collection of all known inscriptions, organised primarily by province. Today it remains an important reference work in epigraphy, with additions since being made to complete its content.
