A Few Questions

[Robert Vermaat]

As for Fullofaudes, I'd imagine he died fighting against the Saxons, while Nectaridus fell in the north, though the lack of concrete evidence either way gives me room for a bit of interpretation. Also, Ammianus suggests the Wall garrisons rebelled and mutinied, allowing the invaders through, this doesn't suggest it wasn't manned (I very much doubt that) but that they conscientiously betrayed the Roman authorities, and the areani played a bit part in that.

In regards to the books you've provided, the second one seems very very useful, than you so much for that. As for the first... it is with no small degree of disappointment I see someone has more or less beat me to my chosen topic (the conspiratio barbarica) - I spent a good amount of time researching the available fiction to see what had already been done (obviously not enough though!) and in a sense my novel will lose its "novelness". Oh well! ;-)

Two things about Ammianus and the events of 367.

1) Ammianus clearly did not know what had happened. Either he did not have the sources who had the details, or the situation had been confused so that no one really had the details. Or the details were suppressed - there is something very strange about this episode as well as the end of it.
2) The word 'conspiracy' is extremely overrated. Anmmianus uses this word to described the origins of the crisis, but earlier in his work he describes a similar 'conspiracy', which includes just about every enemy of the Roman empire. Of course, no historian took that conspiracy as a real event, while chosing differently for the smaller conspiracy of 367. In my opinion, without any good reason. In my opinion, both conspiracies are based on a similar origin - the pen of the author. There was an event in 367, possibly related to enemey incursions, but possibly a rebellion of sorts can also be to blame, resulting in military defeat and chaos, due to or exploited by foreign enemies.

Zosimus totally ignores this 'conspiracy'. He mentions only this:
"About this time, a person named Valentinian for some offence was banished to the island of Britain, and endeavouring there to render himself absolute, was at once deprived of his life and his hopes." (Book IV)
Together with the strange province named 'Valentia', we may have to look for a rebellion with disastrous results, rather than three barbarian peoples being able to make a pact (never seen before or after) and overturning Roman Britain as a result.
