A Romano-Egyptian sword grip

[ROMan]

It sounds quite functional, I would imagine that a sword on a cult statue would just be cast in bronze in one piece, unless it was to be used in sacrifice, when a functional blade would be needed.

There was a 4th century Alemannic king called Serapion mentioned by Ammianus, his father, when in Roman military employ, had become a devotee of Egyptian Serapis. As the military worth of native Egyptians was considered negligible at the time, could a Roman soldier who had been initiated into an Egyptian cult have been the owner?

I don't think there would be a problem finding a Roman worshiping the Egyptian gods, especially in Egypt where this was acquired. It is conceivable that just anyone could have a sword with Horus on it, just as you would have deities depicted on other weapons or armour. But judging by other depictions of Horus in the Roman period it seems to be especially associated with the Pharaoh/Emperor, indeed seemed to personify the Emperor as it had previously personified the Pharaoh. As such it might be a rather pretentious sword to have made unless you were the Emperor - of course, it may have been a gift or other award from the Emperor or his representative.
