- That is a bit misleading. The study of _computus_ was basic to the
- liberal arts astronomy/arithmetic curriculum -- but it has in fact a
- fair amount of interest. Underlying it, there is in fact a kind of
- modeling of nature (the lunar calendar is central to the study) that
- uses residue arithmetic, done without having any notation to help.
- This is a study that goes back to Mesopotamia of circa 1000 B.C.E.,
- or possibly earlier (and which Europe got in trasnplantation through
- the Greeks.) Otto Neugebauer's classic book _The Exact Sciences in
- Antiquity_ in fact opens with a case study of the (gorgeous) calendar
- pages from the 15th century _Tres Riches Heures_ of the Duc de Berry.

- So there *is* some there there. More to the point, it would be like
- saying that solving quadratic equations was the sum total, or 90%,
- of American mathematics. As a description of what has been *taught*
- at a level accessible to the average student, this is fairly accurate.
- Or one could say that until Sputnik, the very pinnacle of American
- secondary math education was trigonometry (in the elementary surveying
- sense).
-
- The "Dark Ages" were an educational disaster zone in Europe, to be
- sure; but as the centuries wore one, specialized study and interesting
- work *was* done in a fair number of places, both in and out of schools.
- And to imagine *why* the Dark Ages were not so nice, it helps to have
- a picture in mind of something like Bosnia continued without pause
- for several centuries.
