More snow on Saturday, which probably removes the risk that we might see patches of ground again before sometime in March. More shoveling last night, though this time Lilly helped. That was the price of borrowing the car today.

Tenchi Meisatsu (Samurai Astronomer) was an interesting movie. As I was watching it yesterday, it occurred to me that I knew little about the pre-Meiji Japanese calendar, except that it had been borrowed from the Chinese, and tossed out in favor of the Gregorian calendar. Tenchi Meisatsu (2012) is the story of Yasui Santetsu, the first official astronomer of the Tokugawa shogunate, and his dramatized efforts to reform the Japanese calendar in the 17th century.

As the reviewer at the imbd points out, that’s an unusual subject for a movie, yet it’s effective. As a Japan Times reviewer points out, “it’s probably the best film about calendar making you’ll ever see.” So far, that’s true. I don’t expect to see an action thriller about Pope Gregory any time soon, and poor old Sosigenes didn’t even rate a mention in the HBO series Rome that I recall, though he seems to have been a character in the 1963 movie Cleopatra.

Another arcane matter: It’s never occurred to me to have a favorite map projection, but I know enough to find this funny. I’m fond of most any map, except for grossly inaccurate tourist maps. That is, the sort that have a few vague lines of actual geography, but which mostly sport drawings of famous places or random fun-time activities. They aren’t real maps anyway.

These are some interesting maps. Especially this one.
