Aeromancy

[1] Aeromancy uses cloud formations, wind currents, and cosmological events such as comets, to attempt to divine the past, present, or future.

[2] Variations on the concept have been used throughout history, the practice is thought to have been used by the ancient Babylonian priests, and is probably alluded to in the bible.

[4]The ancient Etruscans produced guides to brontoscopic and fulgural divination of the future, based upon the omens that were supposedly displayed by thunder or lightning that occurred on particular days of the year, or in particular places.

[3] In contrast, english christian bibles typically translate the same hebrew words into "soothsayers" and "conjurers" or the like.

In Renaissance magic, aeromancy was classified as one of the seven "forbidden arts", along with necromancy, geomancy, hydromancy, pyromancy, chiromancy (palmistry), and spatulamancy (scapulimancy).
