[Verginius Rufus]

The article in Der Kleine Pauly by the great Geza Alfoldy (1935-2011) goes like this (rough translation) (under "Rhizon" it says to see "Risinium"):

Risinium (Risan) on the Adriatic in the bay of Kotor (Cattaro) was under the name Rhizon around 230 B.C. a base of the pirate-state of the Illyrian Ardiaioi. In 167 B.C. it accepted a Roman garrison and received exemption from taxes. Under Augustus the inhabitants were granted civic autonomy (Iulium Risinium) at least a later proves the rank of a "colonia" for the city. The settlement was in the late Republic an important commercial center in which many Italian colonists settled. In the imperial period many knights and senators originated from the civic society.

Omitted a word:

after "later" should read "inscription" ("a later inscription proves the rank").
