TADINUM( Eth. Tadinas: Ru. near Gualdo), a town of Umbria, mentioned by Pliny among the municipal towns of that region. (Plin. Nat. 3.14. s. 19.) It is not noticed by any other ancient author previous to the fall of the Western Empire; but its name is repeatedly found in the epistles of Gregory the Great, and it is evidently the same place called by Procopius Taginae (Τάγιναι, Procop. B. G. 4.29), near which the Gothic king Totila was defeated by Narses in a great battle, in which he was himself mortally wounded, A.D. 552. The site is clearly fixed by the discovery of some ruins and other ancient monuments in 1750 at a place about a mile and a half from Gualdo, where there is an old church consecrated in the middle ages to Sta Maria di Tadino. Gualdois about 9 miles N. of Nocera(Nuceria), close to the line of the Flaminian Way: hence there is little doubt that we should substitute Tadinas for Ptanias,a name obviously corrupt, given in the Jerusalem Itinerary as a station on the Flaminian Way. (Itin. Hier. p. 614; Wesseling, ad loc.;Cramer, Italy, vol. 1. p. 267.)
