Deity of Mars worshipped in Helvetia
Caturix (Gaulish for "battle king") was the war god of the Helvetii.
Names.
Caturix became known as "Mars Caturix" in Gallo-Roman religion by interpretation as Mars. There was a temple dedicated to Mars Caturix in Aventicum, the capital of Roman "Helvetia", another one in Nonfoux, Essertines-sur-Yverdon. 
Other names (epitheta) of Caturix may have been "Cicollus" and "Caisivus". "Caturix" has itself been interpreted as originating as an epithet of Toutatis.
Etymology.
The Gaulish name "catu-rix" means 'battle-king' or 'battle-lord', stemming from Gaulish root "catu"- ('combat, battle') attached to "rix" ('king'). The root "catu-" is cognate to similar words in Celtic languages, including Old Irish "cath" ('battle, troop') and Old Welsh "cad" ('battle'), and is attested in other Celtic personal names such as "Catigern".
The Gallic tribe of the Caturiges ('battle-kings'), settling in the area of modern Chorges (from Latin: "Caturigumagus") was apparently named after the god. The capital of the Caturiges was called "Eburodunum" (modern Embrun), i.e. the same name as that of Yverdon, suggesting a close relationship between the "Caturiges" and the "Helvetii".
Inscriptions.
Five dedicatory inscriptions to Caturix were found in the area settled by the Helvetii, all of them close to Avenches (Aventicum) and Yverdon (Eburodunum). A sixth inscription has been found in isolation in Böckingen, Heilbronn, Germany.
