Was the Legio IX Hispana stationed on the danube at the-

[Jona Lendering]

I mean was on the danube at the time of it's disappearance

Simple: we don't know. We only know that it disapeared between 122 and 180. That leaves three major wars: the revolt of Bar Kochba, the Parthian war of Lucius Verus (which was provoked by the destruction of a legion), and the Marcomannic wars. The army of the Danube is pretty well-known; the main bases have been excavated. The only evidence for the presence of VIIII Hispana at the Danube is one diploma that mentions a legionary (published in Chiron 2 [1972] 449-457). The date is unknown, but second century. That is very little evidence from a well-researched area.

On the other hand, the Euphrates frontier is not so well-known; there has been little research and many archaeological sites have been inundated. We know for certain that a legion was destroyed in 161, when it invaded -led by "a silly Celt"- Armenia. That this unit was VIIII Hispana is now more or less accepted, but it may also have been XXII Deiotoriana. The matter remains, as Keppie summarizes in his article in the Bohec book, "a subject of contention to this day".
