Celtic Bronze Openwork Brooches – 3rd to 1st Century BC A pair of Celtic bronze openwork brooches of the Iron Age, each formed with a circular central opening, an upper perforated terminal and a rectangular lower section. The geometric openwork construction and symmetrical proportions are characteristic of La Tène-period metalwork, while the surviving green and brown patina with mineral deposits is consistent with archaeological burial. Both pieces retain a strong and clearly readable form despite surface wear from age.
