1. On what date in the Gregorian calendar (the one we use) does this series of monuments begin? End?
2. How would you divide this series of monuments into groups of related monuments (Look at their locations in the site and at the earlier dates they mention). How many years are spanned by each group?
3. How many different dates are associated with the “vulture” glyph? The “fish head” glyph? How do these dates relate to the dates of the monuments on which they are mentioned?
4. How many years separate the earliest date mentioned in each group of monuments from the carving of the latest monument in the group? What do such lengths of time seem to correspond to?
5. How does all this relate to the scenes depicted in relief carving on the fronts of the monuments?
