Tianchan Astrology

Fixed star Tianchan has the spectral type A3, indicating the planetary nature of Venus.

SPECTRAL CLASS A: Great honors, artistic appreciation, unexpected gains, good fortune, riches, good judgment, sociableness, creativeness, idealism, and impulsiveness. A variable star adds a tendency to be argumentative, inconstant and unreliable. Challenging aspects cause wantonness, indiscretion, scandals, foolhardiness, destructiveness, cleverness, many anxious moments and a self-seeking nature. ^[3]

Ma Duanlin (1317)

The one star of Tianchan, within Juanshe, governs doctors and shamans; if it is curved and still, virtuous people will be employed; if it is straightforward and active, slanderers will gain power. If it moves out of the Han River, there will be much falsehood in the world. If there are many surrounding stars, the dead will be as numerous as mountains.^[4]

Song History (1346)

The One Star of Heavenly Slander, located within the Curled Tongue, governs shamans and doctors. Darkness is auspicious; brightness signifies that the ruler accepts flattery. If the star is curved and still, virtuous people will rise; if it is straight and active, many slanderers will emerge, war will break out, and the world will suffer from the harm of gossip. If it moves beyond the Han border, the world will be filled with falsehoods. Numerous surrounding stars indicate many deaths. If the Moon invades, the world will suffer many losses. If the Five Planets invade, treacherous people will be by your side. If the Comet and the Guest Star invade, courtiers will be worried. ^[5]

Constellation Perseus the Champion

12♉02 to 18♊06

PERSEUS. The Champion
Legend. Perseus, the son of Jupiter and Danæ, was furnished with the sword, cap and wings of Mercury and the shield of Minerva. He killed the Medusa by cutting off her head and afterwards rescued and married Andromeda. On his return home he inadvertently killed his grandfather Acrisius and pined away through grief, whereupon Jupiter took pity on him and placed him among the stars.
Influence. According to Ptolemy, Perseus is like Jupiter and Saturn. It is said to give an intelligent, strong, bold and adventurous nature, but a tendency to lying. By the Kabalists it is associated with the Hebrew letter Lamed and the 12th Tarot Trump “The Hanged Man.”
Magical. Frees from envy and witchcraft and preserves from lightning and tempests.” ^[6]
