"The alleged palaces and temples merge into one another by continuous gradations.
Probably a cardinal objective of the Maya architect was to achieve differentiation by height, in many levels marking the rank of the vague functions to which the edifices were dedicated.
At the same time he was always extremely sensitive to the spaces engendered between and among edifices, seeking to achieve large and rhythmically ordered open volumes.
Such open volumes with storeyed changes of level are the most striking formal achievements of Maya architectural history."
