Double-chambered Vessel with Figures and Camelid, 1470-1532. Under the Chim?, ceramic seems to have been a less important artistic medium than for earlier north coast cultures. Accordingly, ceramics were mass-produced with molds and, rather than bearing painted scenes, often have an overall dark surface achieved by firing in a smoky atmosphere. The double-chambered vessel was made after the Inka conquered the Chim? in the 1460s.
