The Philosophical Merlin is an interesting early British effort at utilizing the fortune teller tradition (a number of 18th century systems of prognostication.) With some such texts claiming a Napoleonic origin, this particular work claims to be able to cast the general nativity of the user. This astrological sign they exist under according to the book supposedly governs their life and allows them to predict what affairs are best to delve into. An altogether dated but fascinating occult system.
