 Free sculpture in wood, dating back to the 6th century, is represented by a dignified seated man possibly functioning as a mirror bearer.At least since Late Preclassic times, modeled and painted stucco plaster covered the floors and buildings of the town centers and provided the setting for their stone sculptures.Often, large mask panels with the plastered heads of deities in high relief (particularly those of sun, rain, and earth) are found attached to the sloping retaining walls of temple platforms flanking stairs (e.g., Kohunlich).
