Many metates from Costa Rica show considerable wear from the grinding of a substance, probably maize, on their upper surface. Their use, however, was most likely restricted to ritual occasions. Carved from a single piece of volcanic rock with only stone, wooden, or other perishable tools, they exhibit remarkably graceful lines and proportions; intricate low-relief volutes and decorative works on the tripod legs set off the sweeping curve of the plain metate plate. The zoomorphic effigies, such as this avian metate, may have been clan symbols or deity representations. Elaborately sculpted, this important metate perhaps was used in grinding maize for ritual consumption, or was reserved for special occasions and limited to wealthy or high-status households. A fine example of such special sculptures, this avian met ate embodies the artistic grace of curving lines of the top plate and delicate carvings of the tripod legs. The carved avian head is undoubtedly beautiful, well suited for special ritual occasions. A work of art with an important function, this metate's beauty is surely to last for times to come.
