From the Lion of Braunschweig, a brass monument cast in 1166, about 60 samples were analyzed. Though the lion appears to be homogeneous (apart from numerous repairs), it was found that quite different compositions of brass occur. A detailed examination of the sculpture revealed vertical boundaries, which on some places had been broken up. It is obvious that the lion was cast by small portions of molten brass of varying composition, which were heated separately and poured one after the other into the mold. -- AATA
