-ātis), a city of Umbria, mentioned both by Silius Italicus and Ptolemy, as well as by Pliny, who enumerates the Arnates among the inland towns of that province. (Sil. Ital. 8.458
; Ptol. 3.1.54
; Plin. Nat. 3.14. s. 19
.) Both Silius and Ptolemy associate it with Hispellum, Mevania, and other cities in the western part of Umbria; and the inscriptions discovered at Civitella d'Arno,
a small town on a hill about 5 miles E. of Perugia, but on the opposite side of the Tiber, leave no doubt that this occupies the site of Arna. Some remains of a temple still exist there, and besides inscriptions, some of which attest its municipal rank, numerous minor objects of antiquity have been discovered on the spot. (Cluver. Ital.
p 626; Vermiglioli, Dell' antica Città d'Arna Umbro-Etrusca,

), be the same with Arna, but this is probably a stake. [AHARNA
