This Adria ("Hadrianus") is Atri, Italy on the coast of Abruzzi south of Ancona. "Praetutia" is "Interamnia Praetutia", capital city of the Petrutii. From Interamnea comes Teramo and from Praetutia comes "Aprutium", later "Abruzzo". The coast of Abruzzo was in Augustus' Region IV; however, Pliny does not say that the Abruzzo was the largest part of Gallia Togata, only that it was the largest part of the region settled by Sicilians and Liburnians. Similarly if "Hadrianus" is taken to be Adria in Veneto then Gallia Togata would appear to be a synonym for all Gallia Cisalpina. However, Veneto is not "this side of Rimini."
