This from the 5th century...hope we could help in your search.. https://sacredsites.com/europe/russi...of_russia.html
Religious IMO.. St. George..
I'd rather be A "RaD Man than a Mad Man "
It definitely appears to be religious and I think that St. Sergios is on the centerpiece. It's size is probably twice as big most pilgrim flasks so maybe it is for a priest. Thank you for all of your help,
