 Several solutions for dividing up and ordering the stuccoed surfaces of buildings were applied, serialization being one of them.The Early Classic walls of the 'Temple of the Night Sun' in El Zotz consist of a series of subtly varied deity mask panels, whereas the frieze of a Balamku palace, also from the Early Classic, originally had a series of four rulers enthroned above the open ophidian mouths of four different animals (a toad among them) associated with symbolic mountains.Conversely, friezes may be centered on a single ruler again sitting on a symbolic (maize) mountain, such as a frieze from Holmul, with two feathered serpents emanating from below the ruler's seat, and another one from Xultun, on which the ruler carries a large ceremonial bar with emerging jaguar-like figures.
