The geography of Celtic personal names in the Latin inscriptions of the Roman Empire

The study of Celtic proper names in the Roman Empire is still in its infancy, but it has come far since Alfred Holder began publishing his monumental Alt-keltischer Sprachschatz in 1896. However, two recent reference volumes by Marilynne Raybould and Patrick Sims-Williams, A Corpus of Latin Inscriptions of the Roman Empire Containing Celtic Personal Names (henceforth Corpus) and The Geography of Celtic Personal Names in the Latin Inscriptions of the Roman Empire (henceforth Geography), make a crucial contribution to this field.
