Fortune telling and divination is mostly the subject of the pretty patents (below), a quick penny-ante for the fulfillment of the instant treatment of possibility. reckoning via mechanical means,easing folks out of the necessity to think about What May Come, and also, possibly, relieving some of them of the possibilities of worry should the fortunes agree with their hopes. And desires. Opposite, for the opposite.
This thinking goes back a long way into dark and dusty time, though it becomes interesting (to me, anyway) when it gets wrapped up in Renaissance magic and science.
I'm not sure what it reveals except for what people might have wanted to believe in during different periods of time.
Anyway, the patent drawings are pretty.
The ways of telling fortunes are broad and numerous and may have been dictated by the stuff that was readily available at hand; a veritable alphabet can be quickly summoned to deal with the most common of the sort:
Alectromancy (telling the future by relatively brainless modern dinosaur roosters pecking at the ground for stuff);
Astrology (thinking that the motions of stars that are light years away from the observer in a vast sea of space and their annotation on an infinitesimally small speck of universe dust called "Earth" can somehow interact with living organisms that are 1030000 the amount of space that can be affected by the light from the stars that are 1/1,000,000,000 of the age of those stars);
