MÉRIDA, MEXICO—According to a report in Fox News Latino and the Mexico City newspaper Excelsior, Beatriz Quintal Suaste of the Yucatán National Institute of Anthropology and History says that an observatory at the Early Classic Maya site of Acanceh may have helped priest-astronomers track the movement of the planet Venus. The third-brightest object in the sky after the sun and the moon, Venus is thought to have been represented in Maya mythology by a god named Noh Ek. The new study suggests that the southern edge of the observatory aligns with the northernmost position of Venus in the night sky. Three codexes found at the site support the idea that the ancient astronomers would have been able to track Venus’s 584-day cycle through the sky from the observatory.
