LEDUS or LEDUM, as Mela (2.5) names it, a small river of Gallia Narbonensis. Festus Avienus ( Ov. Marit. 590) names it Ledus. Mela speaks of the Stagna Volcarum, Ledum flumen, castellum Latera.The Ledus is the Lez, which passes by Sextantio, to the east of Montpellier, and flows into the Etang de Magueloneor Perolsbelow Latera, now Latesor Latte. Pliny (Plin. Nat. 9.8) gives the name of Stagnum Latera to this Etang, and he speaks of it as abounding in mullets, and describes the way of taking them. The mullet is still abundant there. Pliny places the Stagnum Latera in the territory of Nemausus ( Nîmes), which is at some distance. But the Etangand the Castellum Latera may be among the many small places (Plin. Nat. 3.4) which were made dependant on Nemausus (Nemausiensibus attributa). [G.L]
