Early references 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
Râșnov. The archaeological research at Râșnov 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
Flămânda on the
Danube and stretching northward to Cumidava (now Râșnov). Cumidava had a military road link with
Angustia (now
Brețcu), the farthest east of the Roman campus in Dacia.
From a Dacian town to a Roman military castrum The Roman military
castrum Cumidava was identified at 4 km northwest of the city
Râșnov, at the common border with the city of
Vulcan. == Sinaia lead plates ==
