Some have put it at Purgessimus, some at Prosascus near the source of the Natisone (Natisio), still others at Borgo Bressana, and finally, and most definitively, near Brischis just outside the city.
Niektórzy wskazują na Purgessimus, inni na Prosascus niedaleko źródeł Natisone (Natisio), a jeszcze inni na Borgo Bressana, a ostatecznie w pobliżu Brischis tuż za miastem.
