Belomancy
A method of divination by arrows that dates as far back as
ancient Chaldea. It existed among the Greeks, and still later
among the Arabians, although its use was forbidden by the
Quran. One popular method was to throw a certain number of
arrows into the air, and the direction in which the arrow inclined
as it fell pointed out the course to be taken by the enquirer.
Divination by arrows is related to rhabdomancy.
