It is possible to attribute the Khalchayan reliefs to the first century BC archaeologically, but the historical events reflected in them belong to an earlier period, i.e. to around the middle of the second century BC.
The knights in chain-mail armour have analogies in the Khalchayan reliefs depicting a battle of the Yuezhi against a Saka tribe (probably the Sakaraules). Apart from the chain-mail armour worn by the heavy cavalry of the enemies of the Yuezhi, the other characteristic sign of these warriors is long side-whiskers (...) We think it is possible to identify all these grotesque personages with long side-whiskers as enemies of the Yuezhi and relate them to the Sakaraules (...) Indeed these expressive figures with side-whiskers differ greatly from the tranquil and majestic faces and poses of the Yuezhi depictions.
