The term 'ASTROLOGER's aids' refers to the tools used by astrologers to practice their craft. These tools include charts, which are diagrams that show the positions of the planets and stars in relation to each other. Charts are used to interpret the influence of the celestial bodies on human life. Other tools used by astrologers include ephemerides, which are tables that list the positions of the planets and stars at any given time, and horoscopes, which are predictions based on the positions of the planets and stars.
