Municipium in Picenum, tribus Velina, Regio V, established in the 2nd cent. BC on the left bank of the upper Flusor (modern Potenza) (Str. 5,4,2; Ptol. 3,1,52; Plin. HN 3,111); located 2 km to the east of San Severino Marche near Macerata. S. was on a connecting road between the Via Salaria and the Via Flaminia (It. Ant. 312; 316; cf. CIL IX 5936). Remains of the city wall survive. The existence of a 7th cent. BC Piceni settlement with a necropolis at Pitino 4 km to the northeast of S. has been demonstrated.
