[8] During the 6th century BC, the city of Gelonus was built in the country of the Budini, where the Gelonians set up an important industrial, commercial, and political centre.
The kings of the Budini, Gelonians and Sarmatians accepted to help the Scythians against the Persian attack, while the kings of the Agathyrsi, Androphagi, Melanchlaeni, Neuri, and Tauri refused to support the Scythians.
[17] The Gelonians and Budini brought ores from outside to the industrial section of the city of Gelonus, where iron and copper were smelted from them.
[11] The Gelonians and the Budini participated in the ancient trade route which started from the ancient Greek colony of Pontic Olbia on the northern shore of the Black Sea and continued to the north-east into the steppe and forest-steppe regions.
[11] The Gelonians corresponded to a group of the archaeological Scythian culture which was located outside of Scythia.
