Astrology, a science founded on a presumed connection between the heavenly bodies and human destiny as more or less affected by them, a science at one time believed in by men of such intelligence as Tacitus and Kepler, and few great families at one time but had an astrologer attached to them to read the horoscope of any new member of the house.
