The Cupisnique (ca. 1000-200 B. C.) and the Moche (ca. 100 B. C.-A. D. 800) inhabited much of the same territory of Peru's north coast in Precolumbian times, and both are noted for their extraordinary and distinct artistry. Despite the distinctiveness of the two art styles, various similarities between them have been noted. One investigation concluded that archaistic copying was the explanation for the similarities (Rowe 1971). In contrast, the present study arrives at the opposite interpretation: that the Moche knew the symbolic content of the earlier images and retained it. Decapitation is a concept that is essentially pan-Andean and, therefore, it is not surprising that both the Cupisnique and the Moche subscribed to it. What is surprising, particularly in view of the universality of the idea, is that both groups employed virtually the same cast of characters. This paper demonstrates a continuity of belief between Cupisnique and Moche societies through an investigation of the Decapitator theme.
