Chama Polychromes
The appearance of a lowland style of ceramic painted cylinders in the highland site of Chama is one of the most visible signs of outside influence in the limited archaeological record of the region. This style of pottery was introduced by a new group, perhaps displaced from its lowland city by constant warfare, who took over the town of Chama. They replaced the local tradition of incised ceramics with a lowland pottery style of narrative scenes painted on cylinders, a shape well suited to such illustration. These painted scenes spread the news of the new rulers far and wide.
