Litavis

Litavis (Gaulish: Litauī 'Earth', lit. 'the Broad One') is a Gallic deity whose cult is primarily attested in east-central Gaul during the Roman period. She was probably originally an earth-goddess. In medieval Celtic languages, various terms derived from *Litauia came to designate the Brittany Peninsula.

Epigraphic evidence


Her name is found in inscriptions found at Aignay-le-Duc and Mâlain of the Côte-d'Or, France, where she is invoked along with the Gallo-Roman god Mars Cicolluis in a context which suggests that she might have been his consort. Also, a Latin dedicatory inscription from Narbonne (which was in the far south of Gaul), France, bears the words "MARTI CICOLLUI ET LITAVI" ("To Mars Cicolluos and Litavis").

Etymology
The Gaulish divine name Litauī ('Earth', lit. 'the Vast One') likely stems from Proto-Celtic *flitawī ('broad'; cf. Old Breton litan, Middle Welsh llydan, 'broad'), ultimately from Proto-Indo-European  ('the Broad One'; cf. Sanskrit Pṛthvī, Greek Plátaia; also Old Norse fǫld, 'earth').

The Gaulish personal name Litauicos ('sovereign', lit. 'possessor of the land') is also cognate with the Welsh Llydewig, meaning 'pertaining to Brittany', pointing to a Proto-Celtic term *Litauī-kos, here attached to the determinative suffix -kos.

Medieval terms
The medieval or 'neo-Celtic' names for the Brittany Peninsula (cf. Old Irish Letha, Old Welsh Litau, Old Breton Letau, Latinized as Letavia) all stem from an original *Litauia, meaning 'Land' or 'Country'. In the Irish Lebor Bretnach (11th c.), Bretain Letha means 'Britons of the Continent or Armorica, i.e. Bretons.' Linguist Rudolf Thurneysen proposed a semantic development from an Ancient Celtic term meaning 'broad land, continent' into the Insular Celtic names for the part of the Continent nearest the British Islands.
