(a) Model of the Temple of the Cross, Palenque, designed to show the Construction. The building has three entrances separated by piers. The middle partition is thickened to support the weight of the roof comb which is a trellis for stucco decoration. The sanctuary is a miniature temple in the inner chamber. The walls are built of slabs of limestone set in lime cement.
(b) Detail of Frieze on the Temple of the Cross. The upper band is the sky with stars and planets. A reptilian monster occupies the main panel with human figures as supplementary decorations upon his legs. The Temple of the Cross represents the highest achievement of the First Empire architects, Fifth Century after Christ.

Architecture.
The idea of a civic center is admirably illustrated in Mayan cities, particularly those of the first brilliant period. The principal structures are built around courts or plazas and there is usually an artificial acropolis which is a great terraced mound serving as a common base or platform from which the individual pyramidal bases of several temples rise. At some sites this acropolis is a natural hill which has been trimmed down or added to, but at other sites it is entirely artificial. At Copan there is an especially fine example of artificial platform mound rising from one end of the Great Plaza and affording space for several temples, as well as for sunken courts with stepped sides that may have been theatres. The river washing against one side of this great mound has removed perhaps a third of it and made a vertical section that shows the method of construction. It is apparent that the mound was enlarged and old walls and floors buried.
