During the Classic period, the Maya observed cyclical time through the Calendar Round, in which the Tzolkin or 260-day ceremonial calendar intermeshed with the Haab or 365-day yearly calendar to produce the 52-year cycle so important in Mesoamerican religion. However, they also recognized the need to record linear time as well, observed through the Long Count, in which the current era was calculated from a hypothetical date of 3114 B.C. Elisa Camarena represents date glyphs on this beautiful replica sculpture.
