With the fake Nostradamus quatrains going around e-mail right now, I decided to do some research on him, and found an interesting tidbit.
While Nostradamus was alive, he was in great demand by the various churches and temples in the area. Since this got to be a strain running from place to place, the religious groups got together and hammered out a schedule where they would each get Nostradamus' services for one or two days a month on a rotating basis.
It was the world's first prophet-sharing plan.
