Boy that is a mixture,, isn`t it ?? Mosaic top, Romanesque columns, wood (looks like) base, !! These were made late, 40`s and 50`s,,,some different types later than that, and were intended to be used as combination end tables and lamps !! I have one on each side of my bed but in a different style !! Yours have a hint of Hollywood Regency with all the metal,, not sure but they may be lightweight brass sheet !! Gold color was very "in" at that time so many things used this type decoration to replicate that look !!
