As one of the comments neatly pointed out: looks like a butter churn, with a pole-hole to churn with.
It must be me, but those hard and fast conclusions when it comes to ancient inscriptions and names like the link, I rarely follow:
"Ancient Roman Wooden Barrel with Owner's Name Carved in it."
Why on earth should the owner or user carve his name into a butter churn? Or his "God"?
Certainly if it is found close to a Roman fort, where production in all different area's would have been necessary just for daily life and a relative great pastoral community. Or trade.
I for me think it is idd Ianuarius as mark for the month the butter was produced.
Productiondate if you wish in a Romanesk fort/abbey area, maybe even done by priestlike pastors who like to note everything in their lithurgic language.
