Mayan art was composed of a complex symbolic language with deeply important social functions. Mainly commissioned by kings and other elite figures, works of Mayan art fulfilled both political and social purposes. Because the art functioned as a type of language, to be understood by the entire population, a certain consistency in subject matter and its portrayal was necessary. Whether on a cylinder vessel or a great mural, Maya art essentially depicts ritual. The impressive Maya ceremonies, recorded for posterity in their art, were crucial events in the lives of the kings, and consequently important to society as a whole. In Maya believe, an actual ritual ceremony is directly connected with the art which represents it; both conceived of as a power process that transformed spiritual beings into corporeal beings on the human level, and allowed people and objects to become the sacred beings they represented.
