Bowditch was a pioneer in Maya studies and a terrific writer. In fact, his work was responsible in part for my taking Celestial Navigation (Astro 99) from Francis Wright in Sophomore year as I was building my skills in order to use a box sextant to measure structures in the Northern Peten for suspected celestial alignments . The maya did in fact use a vigesimal place notation system (it dats back to the Olmec who probably invented it) , but their calendric Long Count is actually a modified vigesimal (the 3rd position only goes to 18 uinal) to roughly approximate a 360 day year. By the way, if one plays with the vigesimal system by using stones (or corn) for units and sticks for fives, it is remarkably efficient at doing calculations. Bowditch was a pioneer when he wrote, but later discoveries proved him wrong about the Mayan not calculating long reaches of time. The Maya were very comfortable with large numbers and skilled at predicting cyclic events. The Maya had a fully developed notion of zero. And there are accurate eclipse tables in the Dresden Codex, and they of course understood Venus in the morning and evening star apparition to be the same body. In addition to the Dresden's Venus tables, they did extensive calcs of Mercury's apparitions and accurately predicted of the periodicity of Mercury's rising/setting bearings. There are numerous deep time calcs in the Dresden Codex, and my favorites are several stela at Copan that reach back millions of years. In this instance, the dates of course were mythic, an attempt at giving temporal credibility to the upstart rulers. But they clearly loved calculations. But there are countless other instances of the Maya demonstrating calendric virtuosity and sometimes no small sense of humor. Maya is a language that lends itself to puns (for example, in Tzotzil maya, "- bol" can mean both "stupid" and "in-laws.", and there are even puns to be found in their heiroglyphic texts. This instinct to tie the calendar, human events and the movements of the skies is quite alive among the Maya today, hidden behind the thinnest veneer of Christianity. By the way, this eve's mercury/venus skyshow would have been just the sort of event the Maya would have loved. best -p On Apr 5, at , Frank Reed wrote: > You mentioned the Classic Maya calendar.
