This guy was appointed consul in the Eastern Roman Empire in 491 when he was 10 (ten) years old. As far as I know this was a rather irregular proceeding - I don't recall other cases where children were appointed consuls (the only thing that comes to mind is a certain horse but he didn't get the job in the end).
Presumably this was done because the boy belonged to an important family of the military aristocracy and the emperor wanted to show a token of appreciation for their support. But the question still remains - why in this particular way? It has a very un-Roman feel about it. It would have made more sense to make the boy's father consul, wouldn't it? But perhaps the emperor didn't want to raise this man too high so he gave the plum title to his son instead?
And of course, I looked up the date - 491. It's just when Zeno died and Anastasius succedded him, so there is a good chance the weird proceedings had something to do with the change of regime - but how exactly?
Or, perhaps I am wrong, and it was a Late Roman custom after all to appoint children to the position of consul?
