[net.astro] StarDate: October 22 An Early Solar Eclipse

There used to be some pretty dire consequences for astronomers who
failed to predict an eclipse of the sun.  We'll talk about it -- right
after this.

October 22  An Early Solar Eclipse

Today's date goes down in astronomical history as the anniversary of
the first solar eclipse on record.  The eclipse seems to have been in
the year 2137 B.C.  It was seen in China.

An eclipse of the sun takes place when the moon moves in front of the
sun -- and blots it from view.  But in two thousand B.C., in ancient
China, eclipses were believed to be an attack on the sun by a hungry
dragon.  The strategy was to scare away the dragon by making as much
noise as possible.  It always worked -- the sun always returned to
normal.

There's a story -- probably not true, but famous anyway -- concerning
two royal astronomers on eclipse day, October 22, 2137 B.C.  According
to the story, the two astronomers were called Hsi and Ho -- and they
not only failed to predict the eclipse -- they also were "too drunk in
excess of wine" to perform the rites of shooting arrows and beating
drums to chase away the dragon who was eating the sun.  As punishment,
they were beheaded.

Even if it's not a true story, it does show how seriously people used
to take solar eclipses.  Even today, though it's well known that the
moon in the normal course of things often passes in front of the sun, a
total solar eclipse calls up primitive emotions -- when the sun goes
black -- and daytime turns into darkness.
