Maybe I am going off on a misguided tangent, but it seems to me your piece is similar to the American Federalist Period furniture style - particularly the feet and legs of said furniture style. This furniture was made in America by such famous masters as Duncan Phyfe, and was
based on British furniture from the George III era. Since George III was not a popular King in the American colonies in those days (think American Revolution), his name was not associated with the style, instead using the Federalist title to reflect the new nation's ideals. I would take this a step further and state that PERHAPS the British style, which was borrowed by the early American masters, may have been
based on a Roman style. I think you have a very old piece of something, very possibly Roman. At least I hope so - that would be very exciting.
Check out the leg on the piece of Federalist (American 18th century fine furniture) furniture circled below. Notice the general similarity to your piece of bronze? The similarity between the two is upon which I've based my supposition. In other words, I'm winging it.

Hi I can see what you mean ,cheers Robert,.
