Maya civilization [SEP] Astronomy
Illustrations in the codices show that priests made astronomical observations using the naked eye, assisted by crossed sticks as a sighting device. Analysis of the few remaining Postclassic codices has revealed that, at the time of European contact, the Maya had recorded eclipse tables, calendars, and astronomical knowledge that was more accurate at that time than comparable knowledge in Europe. The Maya measured the 584-day Venus cycle with an error of just two hours. Five cycles of Venus equated to eight 365-day "haab" calendrical cycles, and this period was recorded in the codices. The Maya also followed the movements of Jupiter, Mars and Mercury.
