The double spout and bridge vessel form was common to cultures on the south coast of Peru from the Early Horizon period (900–200 B.C.), appearing in Paracas and Nazca (Nasca) ceramic arts. By the 7th century, the highland Huari (Wari) began increasing their interaction with coastal Nazca culture, sharing technical and visual traits through this cultural exchange. This included the blending of Nazca polychrome slip-painting and the coastal double-spouted vessel form with Huari visual motifs.
