Lugdunum, a city and colony of Gual; according to Herodianus a large and opulent city, now called Lyon, in central France. The Roman mint at Lugdunum was open 15 B.C. - c. 90 A.D., 195 - 196 (for Clodius Albinus), and c. 254 - 423 A.D. (mintmark PLG).
Strabo wrote, "The Romans possess Lugdunum, founded below a ridge at the confluence of the Arar and the Rhone. It is the most populous of all the other cities except Narbo; for it is a centre of commerce, and the Roman emperors strike their silver and gold coinage there." (4.3.2)

Havercamp (ad Morell Fam. p. 26) states that Lugdunum was made a Roman municipium under the provincial quaestorship of M. Antonius Creticus, the father of Mark Antony the triumvir. It was furthermore invested with the jus civitatis Romanae by the Emperor Claudius, who, by his mother Antonia, was related to the Antonii.
An ancient copy of the decree of Claudius, upon brass plates, is preserved at Lyon. They were discovered in 1528.
