Late roman officer and Lorica Musculata!

[Caballo]

Just a couple of well known sources:-



Again, as mentioned in the earlier thread, note the shoulder pieces on Honorius' musculata.

Subject to all the medieval copyist issue, the Notitia Dignitatum, where the copyist has clearly illustrated both mail and some kind of plate chest armour.



The columns of Arcadius and Theodosius









Interesting discussion on the columns and also musculata here http://www.ancient-warfare.org/rat.html?...=20#289400

Overall, I think you'd have a strong case for a musculata with that magnificent helmet. The case is on iconography rather than archaeological finds, but I wonder whether the small number of musculata finds would tend to be classified as earlier rather than Late Roman unless very clearly stratified and incontrovertibly datable?
