Treasured Trash: The Sacred Significance of Ceramic Fragments in Elite Ritual Contexts at Postclassic Xaltocan, Mexico

Abstract

In this article, I examine the use of ceramic fragments to mark sacred spaces at the Postclassic central Mexican site of Xaltocan. Recent excavations in Xaltocan's central precinct revealed a series of ritual features dating to Xaltocan's Middle Postclassic period (a.d. 1240–1350) that were carefully constructed with ceramic fragments. I argue that this practice might represent an effort on the part of Xaltocan's Postclassic leaders to mark these features as sacred. Although Xaltocan was ruled by Otomi peoples during this time, the careful incorporation of ceramic fragments into ritual spaces might be related to the Nahua concept of tlazolli and possibly reflects the increasing influence of Nahua ideologies across the Basin of Mexico. Despite its generally negative connotations, tlazolli was a powerful substance that central Mexicans could manipulate to energize ritual spaces. By carefully reordering ceramic fragments in and around ritual features, Xaltocan's leaders might have imbued these spaces with sacred energy. While the concept of tlazolli might have been quite widespread during this time, the specific practices discussed in this article appear to have been isolated to Xaltocan's Middle Postclassic leaders. Perhaps the specific practices observed were an invention of Xaltocan's Middle Postclassic leaders that never spread.
