The Cognomen PERVSIANVS came thinking that this name could mean from the land south of the Aesis river and, in general, from Central Italy.
This is a consequence of the theory expressed by Augusto Ancillotti, a linguist of the Perugia University, found in his book "Le tavole di Gubbio e la civilt� degli Umbri", Iama 1986 (Ancillotti and Cerri).
The word PERAZNANIE is in the Tabulae Euguvinae(2nd Table, B side, line 7). According to Ancillotti this term come from PER-AISIN, formed by
Giacomo Devoto, 1940, ex president of the Accademia della Crusca sees in the Table IIb, a list of all the federate tribes of the community of Gubbio, the town where the tables were found and still are, to whom the sacrifice was done. He translated the term PERAZNANIE as connected with PERAZNANI (or PERSNATI), from PERASNA, ancient name of Perugia.
*Other translation to the Tabulae Eugubine are, among the others: by Stephanus of Cremona, Filippo Buonarrotti, Scipione Maffei, Giacomo Devoto and, lately, Aldo Luigi Prosdocini of University of Padua, Mel Copland and, as said Augusto Ancillotti of University of Perugia.
