Religion- Mayan religion revolves around time. They developed a number of different calendar systems. One of their man calendars was one called tzolkin, which means sacred calendar. It consisted of 260 days. In addition to tzolkin, they had another one called tun, which had 360 days, plus an additional 5 days that were considered unlucky days. These were the 2 central calendars, but they also had, a half year lunar calendar, a Venus calendar, and a cycle of the gods. These calendars made the Mayans the most accurate predictors of time; they were only off by one day, every 6,000 years. These calendars marked many days of religious celebration. Religious ceremonies consisted of the following; dancing, sacrifice and prayer. The reason for sacrifice was this; the gods needed support from the Humans otherwise, they would but be capable of upholding the duties of a God. The two most often sacrificed things were food and human blood. The amount of blood that the person had to give depended on the social rank of the person. The higher up you were on the social ladder, the more blood was expected during sacrifice. Sometimes a person would even have to give their heart to the gods in sacrifice. They would be held down, cut open, and they would be required to rip out their own heart. The mayans believed that only people who had been sacrificed, hung, or died on childbirth would be the ones to go to the afterlife. That’s why people were so willing to donate themselves to the gods, because everyone who didn’t went to hell. The cross was a symbol for the tree of life. They worshiped Nature Gods, especially the gods of rain, sun, and maize.
