Maya eccentric flint

250–900 CE, Maya

Eccentric flints were placed in caches beneath stelae and temple floors at Classic Maya cities such as Copán, Quiriguá, Tikal and the Belize sites, usually in sets of nine or more. The Belize and Petén cherts allowed large, thin pieces up to 400 mm long showing profiles of kings and gods; obsidian eccentrics are smaller. Nearly all on the market came from looting of cache deposits, and Belize, Guatemala, Honduras and Mexico prohibit export.

Diagnostic traits

A bifacially flaked chert or obsidian object of deliberately non-utilitarian form, such as a human profile, scorpion, crescent or notched lozenge, often with multiple projecting heads.

Identification

An eccentric is not a tool: edges are unworked for cutting, symmetry is thematic rather than functional, and the flaking is fine and invasive. Large Maya bifaces and 'macroblades' are utilitarian and plain. Modern eccentrics made in Belize and Guatemala for tourists are the main confusion.

Reproductions and fakes

Modern knappers in Belize and Mexico produce eccentrics from the same honey-coloured chert; genuine pieces have a patina and surface sheen from burial, sometimes with cinnabar or lime residue in the flake scars, while copies are bright and uniformly fresh. Any eccentric flint offered without a pre-1970s provenance should be treated as looted or modern.
