Is it true that attila set in the throne of Roman Emperor while being painted and the emperor itself have seated from his right hand side footing?

im sorry but im not sure but you could look it up on google I never hear this one, but if it is true it happened when Attila was young and lived in Rome under the hostage exchange program used in that time. Attila and Aetius had known each other since childhood when Attilla was a hostage of the Western Romans. Aetius also served as a hostage to the Huns and the Visigoths. After Atilla and his brother Bleda became kings of the Huns, Attila never met a Roman emperor to my knowledge.
