Caballo Muerto is an archaeological complex located on the northern coast of Peru, in the Moche Valley, in the Laredo District of La Libertad Region. It represents a series of mound sites that span both the Initial Period and the Early Horizon. This site became prominent during the period of the Cupisnique culture. It includes about a dozen architectural sites built upon interlocking platforms. One of them is the important site of the Huaca de los Reyes. It has been declared as belonging to the Cultural Heritage of Peru by the Decree No. 999 of 4 October 2001.
Caballo Muerto was discovered in 1972 by archeologist Michael E. Moseley of Harvard University, then director of the Chan Chan-Moche Valley Project. Other archaeologists working on the project include Luis Watanabe, Thomas G. Pozorski, and Jorge Ruiz Barcellos.
The archaeological complex of Caballo Muerto features stone and adobe constructions, with mud used as mortar. It consists of a dozen ceremonial buildings on constructed platforms, among them the Huaca de los Reyes. Several of these buildings exhibit a "U-shaped" layout that is common for Cupisnique sites. The walls are decorated with reliefs depicting snakes, cats and other images. Apart from the Huaca de los Reyes, there are the following constructions:
The estimated volume of material used for the six Early Formative Caballo Muerto Complex mounds is about 510,000 cubic meters; construction took place over a period of about 500 years.
Huaca Herederos
Huaca Herederos Chica is a monumental site that is part of the Caballo Muerto Complex. This mound was excavated from 1970 to 1973, and is now partially destroyed. It represents a superposition of several phases of occupation and building over some 1000 years period—each phase separated by phases of abandonment. Some of the architectural elements here are similar to those of the Kotosh Religious Tradition at the highland sites of La Galgada and Huaricoto as well as in the coastal Casma Valley. Huaca Herederos Chica was abandoned from 1200–400 CAL B.C. only to be reoccupied and rebuilt in the late Early Horizon.
Huaca de los Reyes
The most important and well studied in this area is the site of Huaca de los Reyes, showing a very complex structure with a "U-shaped" layout. It also includes overlapping platforms featuring access stairs, with plazas and hypostyle halls. The site includes friezes, as well as the giant heads constructed of clay representing characters with feline features, similar to Chavin style, yet preceding the Chavin chronologically.
Economy
The economy of the inhabitants of Caballo Muerto was based on the use of irrigated land reclaimed from the desert. Irrigation canals were constructed. The proteins were obtained from land animals like deer; later, llamas were consumed. The people of Caballo Muerto, belonging to the Cupisnique culture, were the direct ancestors of the great Moche civilization.
