Star-shaped mace heads were a common form for clubs and weapons from at least the Early Intermediate Period (200 B.C.E.-600 C.E.). The first examples appear in stone, associated with Chavín and Salinar cultures. The succeeding Moche and Nasca developed copper mace heads, which they depict in painted scenes of hand-to-hand combat on ceramic vessels. The pointed metal maces would remain popular throughout Andean cultural history. This metal mace head is composed of arsenical copper (or arsenical bronze) with five long cast points. The copper alloy composition suggests that this mace head dates to at least the Middle Horizon (600-1000 C.E.) when such alloys appear within the central Andean regions.
