The Moche people of northern Peru (firstseventh century) were among the first to use copper, often with the addition of arsenic to harden the metal and improve the quality of the cast. Moche metalworkers hammered most of their precious metalsgold and silverinto objects of sheet metal, but many works in copper were cast by the lost-wax technique. The Chimú people, who made this ceremonial knife, inherited the rich cultural and artistic traditions developed by the earlier Moche. Clearly a ritual object, indicated by the delicate, projecting details and attractive silhouette, the knife has a semicircular blade. The flat undulating shaft is embellished with circles in relief; stylized birds project from its sides. At the top is a human head wearing a headdress with mushroom shapes. The detailed facial featureswide staring eyes and open mouth framed by age wrinklesgive the face a startled look. The holes in the earlobes once held ornaments. The object is cast of a copper/arsenic alloy; its surface is now covered with copper corrosion developed over many centuries of burial.
