The astrological influences of the constellation Leo

Ptolemy makes the following observations: "Of the stars in Leo, two in the head are like Saturn and partly like Mars. The three in the neck are like Saturn, and in some degree like Mercury. . . . Those in the loins . . . Saturn and Venus: those in the thighs resemble Venus, and, in some degree, Mercury." It is said that the stars in the neck, back and wing all bring trouble, disgrace and sickness affecting the part of the body ruled by the sign, especially if they happen to be in conjunction with the Moon. By the Kabalists, Leo is associated with the Hebrew letter Kaph and the 11th Tarot Trump "Strength." [Robson, p.48.]

The astrological influences of the constellation Leo given by Manilius:

"Who can doubt the nature of the monstrous Lion, and the pursuits he prescribes for those born beneath his sign? The lion ever devises fresh fights and fresh warfare on animals, and lives on spoil and pillaging of flocks. The sons of the Lion are filled with the urge to adorn their proud portals with pelts and to hang up on their walls the captured prey, to bring the peace of terror to the woods, and to live upon plunder. There are those whose like bent is not checked by the city-gates, but they swagger about in the heart of the capital with droves of beasts; they display mangled limbs at the shop-front, slaughter to meet the demands of luxury, and count it gain to kill. Their temper is equally prone to fitful wrath and ready withdrawal, and guileless are the sentiments of their honest hearts" [Manilius, Astronomica, 1st century AD, p.237.]
