The dry climate favored the adornment of outer walls by color, and those of the Chimu palaces were covered with very tasteful sculptured patterns. Figures of colored birds and animals are said to have been painted on the walls of temples and palaces. Silver and gold ornaments and utensils, mantles richly embroidered, robes of feathers, cotton cloths of fine texture, and vases of an infinite variety of curious designs, are found in the tombs. Cieza de Leon gives us a momentary glimpse at the life of the Chimu chiefs. Each ruler of a valley, he tells us, had a great house with adobe pillars, and doorways hung with matting, built on extensive terraces. He adds that the chiefs dressed in cotton shirts and long mantles, and were fond of drinking-bouts, dancing and singing. The walls of their houses were painted with bright colored patterns and figures. Such places, rising out of the groves of fruit-trees, with the Andes bounding the view in one direction and the ocean in the other, must have been suitable abodes for joy and feasting. Around them were the fertile valleys, peopled by industrious cultivators, and carefully irrigated. Their irrigation works were indeed stupendous. “In the valley of Nepeña the reservoir is three fourths of a mile long by more than half a mile broad, and consists of a massive dam of stone 80 feet thick at the base, carried across a gorge between two rocky hills. It was supplied by two canals at different elevations; one starting fourteen miles up the valley, and the other from springs five miles distant.”[1307] [Illustration: SECTION OF A MUMMY-CASE FROM ANCON. [After a cut given by Ruge, following a plate in _The Necropolis of Ancon_. Wiener (p. 44) gives a section of one of the Ancon tombs.

The researches of Reuss and Stübel at the necropolis of Ancon, near Lima, have been most important. Numerous garments, interwoven with work of a decorative character, cloths of many colors and complicated patterns, implements used in spinning and sewing, work-baskets of plaited grass, balls of thread, fingerrings, wooden and clay toys, are found with the mummies. The spindles are richly carved and painted, and attached to them are terra cotta cylinders aglow with ornamental colorings which were used as wheels. Fine earthenware vases of varied patterns, and wooden or clay dishes, also occur.
