LIGAUNI a people of Gallia Narbonensis, mentioned by Pliny (Plin. Nat. 3.4): Regio Oxubiorum Ligaunorumque: super quos Suetri, &c.The next Regio to the east that he mentions is Regio Deciatium.If we can make a safe conclusion from Pliny's text, the Ligauni must have been close to the Oxybii, with the Deciates to the east, and somewhere where between the Argenteus river and Antipolis, Walckenaer ( Géog. &c. vol. 2. p. 42): places the Ligauni in the parts about Saint-Vallier, Callian, and Fayen.
