History of the star: A star in the left knee of the Lion Leo.

The astrological influences of the constellation: The Lion is associated with the Hebrew letter Kaph and the 11th Tarot Trump "Strength". (Fixed Stars and Constellations in Astrology , Vivian E. Robson, 1923) 

The astrological influences of the constellation 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.]
