Fixed Star Regulus Astrology
“According to Ptolemy it is of the nature of Mars and Jupiter, but most later authors liken it to Mars only, while Alvidas states that it is similar to the Sun in good aspect to Uranus. It gives violence, destructiveness, military honor of short duration, with ultimate failure, imprisonment, violent death, success, high and lofty ideals and strength of spirit, and makes its natives magnanimous, grandly liberal, generous, ambitious, fond of power, desirous of command, high-spirited and independent. From Regulus, a Little King, and often called Cor Leonis, the Lion’s Heart, and symbolically the Crushing Foot. It was one of the four Royal Stars of the Persians in 3,000 B.C., when, as Watcher of the North, it marked the summer solstice.” 
“It may convey royal properties, noble mind, frankness, courage. The importance of this star is accentuated by its nearness to the ecliptic. Its effect is in the best sense that of Jupiter and Mars. On the Ascendant, it will give a courageous and frank character, especially if in conjunction with the Sun, Moon, Jupiter or Mercury. Positioned on the MC, Regulus will raise the native to high positions in life, positions far exceeding the environment the native was born into. On the MC it is not only a good omen for a military career, but also for careers connected with the public, such as lawyers, civil servants, bankers and the clergy, especially if Regulus is also in conjunction with the Sun or Moon or with a benefic stellar body. According to tradition, Regulus conjunct MC will bring with it connections with rulers, honorable people or famous people. If the cosmogram as a whole points to this possibility, Jupiter conjunct Regulus is one of the best configurations for success. People like this can reach high positions, positions of trust, preferment and favors; fortunes. Riches and power could fall to these natives easily. Elsbeth Ebertin had this star near the MC. An old saying goes that Regulus in the 10th house ‘makes astrologers to kings. people in high positions and noble men’. Naturally not everyone who has this configuration will make a ‘Royal Astrologer’ even if he has the necessary knowledge and capabilities. But with Frau Ebertin, this rule was borne out. During the first world war, her book ‘Royal Nativities’ was published. There followed commissions from royal houses and ruling industrialists. Elsbeth Ebertin studied historical events with the planetary configurations in each case and came to the following conclusion; ‘when Mars or Saturn are in conjunction with Regulus, especially exciting events are always recorded e.g. assassinations, coup d’états, revolutions, revolts, demonstrations, overthrow of heads of state and similar events’.”

Conjunctions to Regulus Star
Ascendant conjunct Regulus: Great honor and wealth, but violence and trouble, sickness, fevers, acute disease, benefits seldom last, favor of the great, victory over enemies and scandal. The 145th Consideration of Guido Bonnets is as follows: -” That thou see in Diurnal Nativities whether Cor Leonis be in the Ascendant, that is to say, in the Oriental Line or above it one degree or below it three degrees; or whether it be in the tenth in like degrees, without the Conjunction or Aspect of any of the Fortunes, for this alone signifies that the Native shall be a person of great note and power, too much exalted, and attain to high preferment and honors, although descended from the meanest parents. And, if any of the Fortunes behold that place also, his glory shall be the more increased; but, if the Nativity be nocturnal, his fortune will be somewhat meaner, but not much; but if the Infortunes cast their aspects there it will still be more mean; but if the Fortunes behold it also they will augment the good promised a fourth part, and mitigate the evil as much; yet still, whatever of all this happens, it signifies that the Native shall die an unhappy death; or at least that all his honors, greatness and power shall at last suffer an eclipse and set in a cloud. 
Midheaven conjunct Regulus: Honor, preferment, good fortune, high office under Government, military success. If with Sun, Moon or Jupiter, great honor and ample fortune.
