Final answer:
The claim that the Chavin nose ornament is made of hammered gold alloy is false; it refers to Moche craftsmanship, which is known for its advanced metalwork such as hammering, soldering, and techniques like depletion gilding.
Step-by-step explanation:
The statement that the Chavin nose ornament is made of hammered gold alloy is false. The Chavin civilization predated the Moche, and while they also had metalworking skills, the nose ornament mentioned, specifically identified as belonging to the Moche culture, originated from a different time period and cultural context. The Moche were known for their exquisite metalwork, particularly in creating gold and silver jewelry, including nose ornaments. These artifacts are evidence of their advanced metallurgical skills, including hammering, soldering, and applying advanced techniques such as depletion gilding.
Additionally, the Chavin did not use the same aesthetic in their ornaments as the Moche, whose work often featured intertwined serpents and other motifs distinguishable from the Chavin style.
