In my 30 years of practice, few fixed stars provoke as much curiosity and caution as the Pleiades. Known as the Seven Sisters, this cluster in Taurus has been observed by astrologers since antiquity. Ptolemy described them as of the nature of the Moon and Mars, and Guido Bonatti assigned them a violent, blind quality. When they appear in your natal chart, they are never neutral—they mark a point of intense fate, often involving vision, loss, or sudden upheaval.

The Mythological and Astrological Background

The Pleiades are named after the seven daughters of Atlas and Pleione. In Greek myth, they were pursued by Orion and eventually placed among the stars. The brightest, Alcyone, is often considered the central star. Traditional astrologers like Vivian Robson noted that the Pleiades give “ambition, desire for power, and a restless disposition,” but also “blindness, disgrace, and accidents.” This duality stems from their lunar-Martian blend: emotional sensitivity combined with impulsive action.

In the Liber Astronomiae, Bonatti lists the Pleiades among the “fixed stars of a violent nature,” causing “quarrels, wounds, and sudden death” when rising or culminating with malefics. Yet they also confer a sharp mind and artistic talent when well-aspected. The key is their conjunction with planets or angles—this is where their influence becomes personal.

The Pleiades in the Natal Chart: Conjunctions and Effects

Conjunction with the Ascendant or Midheaven

When the Pleiades conjoin the Ascendant, the native often has striking eyes—large, bright, or unusual—but may suffer from eye problems or accidents affecting sight. I have observed this in several clients who later developed cataracts or experienced eye injuries. On the Midheaven, the Pleiades can bring fame or notoriety, but often through scandal or sudden reversal. A classic example is a public figure who rises rapidly then falls just as fast.

Conjunction with the Sun or Moon

A Sun-Pleiades conjunction in the natal chart gives a proud, ambitious nature, but with a tendency to act rashly. The native may be drawn to leadership but face violent opposition. The Moon here intensifies emotional volatility and a need for security that is rarely satisfied. Robson writes that the Moon with the Pleiades “causes trouble through women and brings loss of reputation.” In my experience, it often indicates a mother who is either absent or overbearing, shaping the native’s lifelong struggle with trust.

Conjunction with Mars or Saturn

Mars with the Pleiades is one of the most dangerous combinations in traditional astrology. It can indicate a violent temper, accidents with sharp objects, or a tendency toward self-destructive behavior. Saturn here brings chronic ailments, especially to the eyes or bones, and a heavy, melancholic disposition. Yet if Saturn is well-placed by sign and house, the native can channel this into disciplined artistic work—especially music or poetry, as the Pleiades are linked to the voice and hearing.

How to Interpret the Pleiades in Your Chart

First, locate the Pleiades at approximately 29°58' Taurus (sidereal) or 0° Gemini (tropical). In modern practice, most traditional astrologers use the tropical zodiac with a 1° orb for conjunctions. Check if any planet or angle falls within 1° of this degree. If so, note the house and aspects. A conjunction with a benefic like Venus or Jupiter can soften the harshness, but the core nature remains testing.

Second, consider the house. The Pleiades in the 1st house affects the body and personality; in the 2nd, financial ups and downs; in the 7th, partnerships marked by conflict or sudden endings; in the 10th, career volatility. The 12th house can indicate hidden enemies or institutional confinement.

Third, look at the ruler of the degree. If the Pleiades fall in a house ruled by a malefic, the effects are more acute. For example, if they are in the 6th house and the 6th house cusp is in Aries (ruled by Mars), health issues may be sudden and inflammatory.
