The walls were plastered and painted with great gods and other mythological features. The Mayans also expressed themselves artistically. Their ceramics were made in a large variety of forms and decorated with complex scenes. The Mayans also designed works of art from flint, bone and shell, along with making decorated cotton textiles. Even metal was used for ceremonial purposes.
Items made with metal include necklaces, bracelets and headresses.
It is evident that all of the structures built by the ancient Mayans were built in honor of the gods. Compounds were built with large open areas, from which all the citizens could view the religious ceremonies taking place on the platforms elevated above the city. On the other hand, the construction of the Castillo, seems to relate to the ancient Maya's obsession with the calendar. For example, each stairway in the temple has 91 steps, making a total of 364 steps in the four staircases, which, counting the platform at the top of the pyramid, equals the total number of days in the solar year. Even more so, each side of the pyramid has nine stepped terraces divided by a stairway, for a total of eighteen sections on each side, consequently, the number of months in the Maya calendar.
