Volscian is attested in an inscription found in Velitrae (Velletri), dating probably from early in the 3rd century BC; it is cut upon a small bronze plate (now in the Naples Museum), which must have once been fixed to some votive object, dedicated to the god Declunus (or the goddess Decluna).

This phenomenon of what might have been taken for a piece of Umbrian text appearing in a district remote from Umbria and hemmed in by Latins on the north and Oscan-speaking Samnites on the south is a most curious feature in the geographical distribution of the Italic dialects, and is clearly the result of some complex historical movements.

The name Marica ("goddess of the salt-marshes") among the Aurunci appears also both on the coast of Picenum and among the Ligurians; and Stephanus of Byzantium identified the Osci with the Siculi, who, there is reason to suspect, were kinsmen of the Ligures.

Besides the Aurunci and the dea Marica and the intempestaeque Graviscae (Aeneis 10.184), we have the Ustica cubans of Horace (Odes 1.17.1), the Hernici in the Trerus Valley, Satricum and Glanica in the Pontine Marshes.
