Description
Fashioned from mottled, light blue-green jade, this plaque is rectangular, with well-rounded corners. A pair of biconically drilled holes pierces the back upper edge of the piece, concealing suspension holes that are not visible from the front. The back side of the plaque is slightly convex, and bears two curving grooves running parallel to one of the vertical sides, probably aborted cuts made during the original blocking out and shaping of the piece. The front side has a gently concave and highly polished surface. In a detailed study of this object, John Carlson (1993) suggests that it represents an effigy copy of an iron ore Olmec mirror. He notes that the dimensions of the concave surface are virtually identical to those known for Olmec mirrors. Although Carlson interprets this item as a "non-functional" copy of an iron ore mirror, it is quite possible that as with the metallic ore examples, this pectoral could have also been used in divinatory scrying. In such divination, the play of light is at least as important as the quality of the reflection. Although rare, other examples of Olmec jade mirrors do exist. The use of mirrors in divination is widely documented in Mesoamerica, and such mirrors often seem to have served as powerful emblems of high office.
