Peru's earliest artwork came from the Cupisnique culture, which was concentrated on the Pacific coast, and the Chavín culture, which was largely north of Lima between the Andean mountain ranges of the Cordillera Negra and the Cordillera Blanca. Decorative work from this era, approximately the 9th century BCE, was symbolic and religious in nature. The artists worked with gold, silver and ceramics to create a variety of sculpture and relief carvings. These civilizations were also known for their architecture and wood sculpture.
