Nantonos, just a thought - i checked my source (Breeze & Dobson 2000, Hadrians Wall, p259) and RIB 1795 is an inscription by the cohors II delematarum, but as i don't have a copy of RIB to access anytime soon (and if anyone would like to put them online as they are doing so wonderfully with the Vindolanda tablets i will love them forever and gladly volunteer my assistance) and i wondered is RIB 1777 associated with RIB 1795 at all, other than location? I appreciate your observation that the location of a unit's origin does not reflect their recruiting ground - this is certainly the case on Hadrian's Wall - but there is a lot of evidence suggesting that regardless of the origins of troops, the unit's gods tend to stay put with them, a look at the names of the gods turning up on Hadrian's Wall long after you expect the bulk of the soldiers to be local is testament to this. Also, any luck on horse headed figures yet?
