Argedava
Argedava (Argedauon, Sargedava, Sargedauon, Zargedava, Zargedauon, Ancient Greek: Αργεδαυον, Σαργεδαυον) was an important Dacian town mentioned in the Decree of Dionysopolis (48 BC), and potentially located at Popeşti, a district in the town of Mihăilești, Giurgiu County, Romania.
Decree of Dionysopolis
This decree was written by the citizens of Dionysopolis to Akornion, who traveled far away in a diplomatic mission to meet somebody's father in Argedauon.
The inscription also refers to the Dacian king Burebista, and one interpretation is that Akornion was his chief adviser (Ancient Greek: πρῶτοσφίλος, literally "first friend") in Dionysopolis. Other sources indicate that Akornion was sent as an ambassador of Burebista to Pompey, to discuss an alliance against Julius Caesar.
This leads to the assumption that the mentioned Argedava was Burebista's capital of the Dacian kingdom. This source unfortunately doesn't mention the location of Argedava and historians opinions are split in two groups.
