The nebulous mass in the breast, called the Præsepe, has the same efficacy as Mars and the Moon. The two placed on either side of the nebulous mass, and called the Asini, have an influence similar to that of Mars and the Sun.

The bright one in the heart, called Regulus,[36] agrees with Mars and Jupiter. Those in the loins, and the bright one in the tail, are like Saturn and Venus: those in the thighs resemble Venus, and, in some degree, Mercury.

Virgo. The stars in the head of Virgo, and that at the top of the southern wing, operate like Mercury and somewhat like Mars: the other bright stars in the same wing, and those about the girdle, resemble Mercury in their influence, and also Venus moderately. The bright one in the northern wing, called Vindemiator, is of the same influence as Saturn and Mercury: that called Spica Virginis is like Venus and partly Mars: those at the points of the feet and at the bottom of the garments are like Mercury, and also Mars, moderately.

Scorpio. The bright stars in the front of the body of Scorpio have an effect similar to that produced by the influence of Mars, and partly to that produced by Saturn: the three in the body itself, the middle one of which, called Antares,[38] is ruddy and more luminous, are similar to Mars and moderately to Jupiter: those in the joints of the tail are like Saturn and partly like Venus: those in the sting, like Mercury and Mars. The nebula is like Mars and the Moon.

The stars at the point of the arrow in Sagittarius have influence similar to that of Mars and the Moon: those on the bow, and at the grasp of the hand, act like Jupiter and Mars: the nebula in the face is like the Sun and Mars: those in the waist and in the back resemble Jupiter, and also Mercury moderately: those in the feet, Jupiter and Saturn: the four-sided figure in the tail is similar to Venus, and in some degree to Saturn.

The stars in the mouth are like Saturn, and partly like Venus: those in the feet and in the belly act in the same manner as Mars and Mercury: those in the tail are like Saturn and Jupiter.

The stars in the shoulders of Aquarius operate like Saturn and Mercury; those in the left hand and in the face do the same: those in the thighs have an influence more consonant with that of Mercury, and in a less degree with that of Saturn: those in the stream of water have power similar to that of Saturn, and, moderately, to that of Jupiter.
