Planetary Cycles & Speculation

J. P. Morgan is famously quoted: "Millionaires don't use Astrology, billionaires do." 17th century scholars already knew about the impact of sunspots, planetary cycles and the like on economies and financial markets - this book is a compilation of their completely rhymed (to gain monarchs' and wealthy merchants' attention) scripts. It also contains images used to advertise the astrological service.
