Cumidava (also Comidava, Komidava, Ancient Greek: Κομίδαυα) was originally a Dacian settlement, and later a Roman military camp on the site of the modern city of Râşnov (15 km from Braşov) in Romania.
After Roman conquest of Dacia, the Dacian name Comidava had been modified by the Latin writers to Cumidava. (Note: It is very common in the Late Latin inscriptions to express the letter "o" by "u", e.g. patrunus instead of patronus 'protector', and Latin rumpia instead of Greek ρομφαια (Rhomphaia) 'Thracian claymore / sword'.)
The name Comidava is a compound of dava ‘town’ and “comi”. The scholars' opinions about the meaning of the Dacian word “Comi/Cumi” include:
Another town named Comidava / Cumidava was situated in the Remesiana’s territory
Castra Cumidava was a fort in the Roman province of Dacia. It is located at 4 km northwest of the city Râşnov, at the common border with the city of Vulcan. The archaeological site is located on the middle terrace of Bârsa River. It includes a defensive line of about 2 hectares.
The inscription found in the fort testifies about a Roman cohort of Vindelici who had taken the name Cumidava (Komidava of Ptolemy) from its place of cantonment. The fact that the Romans preserved the Dacian name is quite suggestive. The native Geto-Dacian population, which became the basis for a new civilization, lent its specific characteristics, while the Latin-speaking colonists introduced Roman traits.
The relatively small castrum (110 m x 114 m) belonged administratively to the Dacia Apulensis. It was continuously used by only two cohorts Vindelicorum Cumidavensis (cohors VI and cohors VI Nova).
