Two Batavi Iuniores?

[Robert Vermaat]

The Notitia Dignitatum is not a document written and published at one point in time. There have been additions and editions added to the document as we have it in it's current form. That is to say, the troops mentioned in the eastern half (Notitia Dignitatum in partibus Orientis) were not edited and are shown where they existed during the original edition in c. 394AD. The troops of the wester half (Notitia Dignitatum in partibus Occidentis) though sometimes moved about inbetween several editions, and they get to mentioned twice or even more (but no longer in their original spot). Sometimes though a vexillation of a unit was sent elsewhere, but still retaining the name of the parent units, and the unit would indeed exist be in two places at the same time.
