Cumidava (also Comidava, Komidava, ) was originally a Dacian settlement, and later a Roman military camp on the site of the modern city of RâÃÂnov (15 km from BraÃÂov) in Romania.
After the Roman conquest of Dacia, the Dacian name Comidava was modified by the Latin writers to Cumidava. (It is 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 ÃÂÿüÃÂñùñ (Rhomphaia) 'Thracian claymore / sword'.)
The name Comidava is a compound of dava 'town' and "comi". Scholars' opinions about the meaning of the Dacian word "Comi/Cumi" include:
Another town named Comidava / Cumidava was situated in the Remesiana's territory
Early references to Cumidava are made by the geographer Ptolemy in his Geographia, in the form Komidava ().
An inscription on stone dedicated to Julia Avita Mamaea, the mother of the Roman Emperor Alexander Severus (dated 222-235 AD), allows the localization of the Dacian settlement Cumidava in the area of present-day RâÃÂnov.
The archaeological research at RâÃÂnov was initiated in 1856 by Johann Michael Ackner and continued in 1939 by Macrea Mihail who also recorded the presence of Dacian pottery during the digs at the Rasnov Roman camp
The inscription found in 1939:
After Roman conquest, a part of the kingdom of Dacia was included in the Roman Empire. Septimius Severus (Roman emperor from 193 to 211 AD) pushed Dacia's eastern frontier approximately east of the Olt River (Limes Transalutanus), constructing a series of 14 camps, over a distance of cca. , beginning at FlÃÂmânda on the Danube and stretching northward to Cumidava (now RâÃÂnov).
Cumidava had a military road link with Angustia (now BreÃÂcu), the farthest east of the Roman campus in Dacia.
The Roman military castrum Cumidava was identified at 4 km northwest of the city RâÃÂnov, at the common border with the city of Vulcan.
Cumidava is mentioned also on the controversial Sinaia lead plates in the form Comidava, which is used as example to debunk the myth about them. According to the director of the Romanian Institute of Archaeology, Alexandru Vulpe, the tablets include only what was known before 1900, for example, the form Comidava from Ptolemy, although now it's known that the correct spelling is Cumidava, as found in 1942 in an inscription.
