According to an ancient legend, of various different tellings, a magician-god named Itzamna was single handedly supposed to have constructed the pyramid in one night. From archaeological excavation however, we know that the pyramid was constructed in five superimposed phases. The legendary association of the pyramid with a magician may be understood as an indication that the structure, and indeed the entire sacred part of the Uxmal complex, had ancient and ongoing use as a mystery school and ceremonial center. It is also interesting to note that the entire city is aligned with reference to the position of the planets then known, with Venus predominating, and that the pyramid of the magician is oriented so that its stairway on the west faces the setting sun at the time of summer solstice.
