The South Node is neither a planet nor a secret reservoir of memories. It indicates the point where the Moon, in its course, crosses the ecliptic from north to south. Opposite it is always the North Node, the reverse crossing located exactly opposite it. Together, they form the nodal axis, essential to understanding eclipses and present in astronomical and astrological tables for centuries.
Western tradition calls the South Node the “Dragon’s Tail” or Cauda Draconis. Authors attribute to it a function of diminution, separation, or departure, but they do not all interpret it in the same way when it encounters a planet. It therefore does not automatically indicate “karmic past,” already acquired talents, or a comfort zone to leave. In a chart, it first shows where something is reduced, dispersed, exhausted, or needs to be shed; the sign, house, their ruler, and nearby planets clarify its nature.
From the Lunar Orbit to the Dragon’s Tail
The Moon’s orbit is tilted relative to the apparent path of the Sun, called the ecliptic. The two planes intersect at two points. At the North Node, the Moon moves toward northern celestial latitudes; at the South Node, it descends toward southern latitudes. The nodes therefore have neither mass, light, nor surface: they are calculated geometric positions.
An eclipse can occur only when the new or full Moon forms close enough to the nodal axis. This proximity explains the ancient image of the dragon devouring the Sun or Moon. The head and the tail do not represent two independent creatures, but the two ends of the same astronomical line.
Traditional point. The South Node is never interpreted on its own. The house that contains it shows where diminution or departure manifests; the sign describes how it occurs; the traditional ruler of that sign indicates whether this withdrawal relieves, impoverishes, simplifies, separates, or ends a situation that has become powerless.
The nodal axis completes its cycle in approximately 18.6 years and generally moves retrograde through the zodiac. Software usually offers a mean node, whose movement is regularized, or a true node, which follows the oscillations of the astronomical calculation. The two positions remain close, but it is advisable to use the same method when comparing several charts or periods.
What the South Node traditionally means
Diminution, separation, and departure
The Dragon’s Tail is associated with what diminishes, leaves a place, comes undone, or loses its capacity to act. This reduction is not always bad. It can lighten a burden, end a conflict, reduce an excess, or break free from a habit that has become fruitless. It becomes more difficult when it weakens a support, resource, alliance, or ability that the situation needed.
The overly simple formula “the South Node is malefic” must therefore be replaced with a more precise question: what is decreasing, under whose authority, and to the benefit or detriment of what? Reducing a debt is not the same as reducing an income; leaving a quarrel does not have the same effect as losing an ally.
A nature akin to Saturn and Mars
Guido Bonatti describes the Dragon’s Tail as feminine, naturally difficult, and analogous to Saturn and Mars. He associates it with decrease, debasement, and loss of strength. According to this doctrine, it diminishes the good of a favorable planet, but may also lessen the harm of a difficult planet. This rule of subtraction explains why the South Node does not produce the same result in every configuration.
William Lilly reports this earlier opinion, then distances himself from it in the name of his practice. He writes that he often saw the Dragon’s Tail greatly increase the harmfulness of difficult planets and bring about obstacles, controversies, or failure when it joins benefics, unless the significators are strong. This historical divergence rules out automatic formulas: the planet’s dignity, sect, rulership, and the chart as a whole must decide.
An axis, not a karmic past
Interpretations that make the South Node the memory of past lives, a spiritual debt, or a set of already mastered gifts are late developments in Western astrology. They do not constitute the doctrine of ancient, medieval, or Renaissance authors. The Dragon’s Tail does not represent a flawed half of the person that must be renounced in order to progress.
The South Node and the North Node describe two poles of the same movement. One marks departure and decrease; the other entry and growth. Their opposition makes it possible to observe how one matter loses ground while another gains it, without turning this movement into a moral judgment or a spiritual imperative.
How to interpret the South Node
An orderly reading begins with the house of the South Node, then examines the sign and its traditional ruler. The opposing North Node always completes the picture. Close conjunctions deserve particular attention, because the subjects of the planet involved are directly entangled in the movement of decrease or separation.
| Element to examine | Interpretive question |
|---|---|
| The house of the South Node | In what area do a decrease, departure, separation, or exhaustion become visible? |
| The sign | How does this withdrawal act: quickly, slowly, materially, through exchange, rupture, or dissolution? |
| The traditional ruler of the sign | Where is it located? Is it dignified, received, direct, retrograde, angular, or weakened? Can it give a useful form to what is coming undone? |
| The opposing North Node | Which area is simultaneously experiencing an entry, an amplification, or a renewed surge of activity? |
| Conjunctions | Is a planet close enough for its functions to be directly diminished, freed, or obstructed? |
| The Sun and the Moon | Was the chart cast near an eclipse season? Are the luminaries actually close to the nodal axis? |
| The mean or true node | Does the calculation method remain identical in all charts being compared? |
The sign of the South Node does not form a second temperament and replaces neither the Ascendant sign, nor the Sun, nor the Moon. It describes the zodiacal terrain on which the decline takes place. Its ruler reveals what may result from it and toward which other area its effects are directed.
To correctly determine its position, use the birth chart generator, then observe the symbol ☋, the house containing it, the opposing North Node, and the planet ruling its sign.
The South Node in the twelve signs
These indications describe how a matter tends to lose strength, become simpler, or leave the field according to the quality of the sign. They are never sufficient on their own to predict a loss. The traditional ruler, the house, and the planets in conjunction determine whether the decline becomes deprivation, relief, fruitful divestment, or difficulty holding on.
| South Node in… | Traditional ruler | Dynamic of decline |
|---|---|---|
| Aries | Mars | Drive, competition, or struggle lose their strength through a swift severing. This position can help you leave a conflict, but it can also make initiative erratic or too quickly abandoned. |
| Taurus | Venus | Possessions, habits, and sources of security are gradually shed. Simplicity frees you from clutter; weakening resources or attachment calls for caution. |
| Gemini | Mercury | Information, contacts, or travel become scattered and must be sorted through. The superfluous is eliminated; lost messages and fragmented commitments remain a risk. |
| Cancer | Moon | Family, domestic, or protective matters experience a decline. A dependency may loosen, while support or a sense of belonging may become less available. |
| Leo | Sun | Visibility, authority, or the need for recognition diminishes. Stepping away from the spotlight can make creativity more restrained; a loss of support or honor calls for examining the Sun. |
| Virgo | Mercury | Tasks, methods, and details are reduced, corrected, or abandoned. Streamlining makes the work clearer; however, an overly fragile organization may fall apart. |
| Libra | Venus | Agreements, alliances, or compromises lose their hold. An unbalanced relationship may come to an end; conciliation, support, or shared resources may also dwindle. |
| Scorpio | Mars | Power struggles, secrets, and shared affairs are untangled through rupture or liquidation. The end of hostility brings relief; a poorly handled crisis can increase the loss. |
| Sagittarius | Jupiter | Distant ambitions, convictions, or promises are brought back to their proper measure. Excess is corrected, but confidence, protection, or the means of expansion may recede. |
| Capricorn | Saturn | Structures and responsibilities slowly erode or reach their end. An old burden can be laid down; authority, security, or a construction may lose its solidity. |
| Aquarius | Saturn | Networks, institutions, or collective projects tighten. The group sheds a rule that has become unnecessary; isolation and loss of support are possible if Saturn is weak. |
| Pisces | Jupiter | Boundaries dissolve and attachments drift away without always producing a clear break. Compassion can free itself from illusion; reference points and protections may also dissolve. |
The South Node in the twelve houses
The house shows the concrete area in which the South Node acts. It is not necessarily something already mastered: it is a place where influence diminishes, a situation empties out, a separation occurs, or the chart invites you to remove what is no longer useful.
| South Node in… | Area concerned | Possible interpretation |
|---|---|---|
| First House | Personal presence, body, initiative, and the way one enters the world. | Erasure, withdrawal, or transformation of self-image. Simplicity can be liberating; a loss of momentum calls for examining the ruler of the Ascendant. |
| Second House | Property, income, acquisitions, and means of subsistence. | Expenses, decluttering, or fewer resources available. Reduction can cleanse an accumulation, but it requires practical management. |
| Third House | Siblings, neighbors, messages, studies, and short journeys. | Contacts become less frequent, information needs sorting, and journeys or studies are interrupted. Simplification must preserve essential exchanges. |
| Fourth House | Home, family, land, inheritance, foundations, and the outcome of affairs. | Leaving the home, sharing an inheritance, or ending a family situation. A root detaches so that another place can grow. |
| Fifth House | Children, creations, pleasures, love affairs, celebrations, and personal works. | Pleasure becomes less central, a creative project is abandoned, or a casual relationship fades. Reducing excess can make joy more balanced. |
| Sixth House | Daily work, service, illness, constraints, employees, and small animals. | End of a chore, reduction of a burden, or disorganization at work. The easing is useful if essential responsibilities remain fulfilled. |
| Seventh House | Partnerships, marriage, contracts, clientele, declared adversaries, and lawsuits. | Separation, renegotiation, or loss of support in a relationship. A conflict may also run its course and give way to a form of independence. |
| Eighth House | Other people’s resources, inheritances, debts, losses, and financial obligations. | Settlement of a debt, diminished outside support, or division of an inheritance. Withdrawal can liberate as much as it deprives. |
| Ninth House | Long-distance journeys, religion, divination, law, higher education, and transmission. | Revision of a belief, interruption of a journey, or intellectual stripping away. A lost certainty may open the way to more rigorous examination. |
| Tenth House | Public action, profession, reputation, dignities, responsibilities, and authority. | Withdrawal from a role, reduced visibility, or the end of a professional cycle. The exit must be assessed with the ruler of the Midheaven. |
| Eleventh House | Friends, allies, protectors, hopes, and the fruits of action. | A tightening network, an abandoned collective project, or a withdrawn favor. A few strong alliances may replace scattered sociability. |
| Twelfth House | Withdrawal, hidden enemies, enclosed places, servitude, large animals, and concealed matters. | Exhaustion of adversity, emergence from isolation, or weakening of what was acting in secret. Invisible protection may also withdraw. |
The South Node associated with the seven planets
The conjunction is the most direct contact with a node. Aspects can supplement the interpretation, but they require tight orbs and should not be given the same weight as a planet placed on the axis. The Dragon’s Tail combines a planet with a movement of reduction or withdrawal; it does not replace its nature, dignity, or rulership.
| Associated planet | What may diminish or come undone | Point to watch |
|---|---|---|
| Sun | Visibility, authority, honor, will, connection to the father or to prominent people. | A voluntary withdrawal can provide protection from noise; a weak Sun may indicate recognition that is difficult to maintain. |
| Moon | Popularity, mobility, domestic life, habits, maternal ties, and changes. | The luminaries’ proximity to the axis must be real before speaking of an eclipse. The ebb can ease a dependency or reduce support. |
| Mercury | Studies, writings, commerce, calculation, negotiations, messages, and journeys. | Filtering information is useful; errors, omissions, and communication breakdowns are less so. Check the documents and terms. |
| Venus | Alliances, affection, pleasures, arts, agreements, gifts, and pleasant resources. | Simplicity can free one from an attachment; harmony, resources, or gentleness in a relationship may also diminish. |
| Mars | Conflict, competition, severance, effort, and the ability to make decisive cuts. | Some authors see the harm diminish, while Lilly reports a strong worsening near difficult planets. Avoid any mechanical rule. |
| Jupiter | Favors, wealth, honors, protection, justice, teaching, and confidence. | Excess can be corrected, but support, expansion, or generosity may lose some of their impact if Jupiter is weakened. |
| Saturn | Structures, responsibilities, lands, duration, discipline, isolation, and constraints. | An old burden may loosen; solidity, patience, or material resources may also diminish. |
When the Sun or Moon is near the nodal axis, birth may occur during an eclipse season. Nevertheless, the degrees, lunar phase, and actual astronomical event must be checked. Simply sharing a sign is not enough.
Traditional correspondences of the South Node

| Latin name | Cauda Draconis. |
| Symbol | ☋ |
| Astronomical nature | Point where the Moon’s orbit crosses the ecliptic, passing from northern to southern celestial latitude. |
| Celestial body | None: the node is a calculated geometric point, without mass or its own light. |
| Opposite point | North Node or Caput Draconis, always located 180 degrees away. |
| General motion | Retrograde through the zodiac, with a cycle of approximately 18.6 years. |
| Astronomical connection | The axis required for solar and lunar eclipses when the luminaries approach it at the time of a new or full Moon. |
| Nature according to Bonatti | Feminine, analogous to Saturn and Mars, associated with reduction and loss of strength. |
| Traditional function | Reduction, departure, separation, dispersion, or debasement of the planet and area concerned. |
| Nuance according to Lilly | An obstacle near benefics and, depending on the practice, a strong increase in harm near malefic planets. |
| Domicile and exaltation | No attribution is sufficiently consistent in the Western tradition to replace the ruler of the sign where the node is located. |
| Calculation methods | Mean node, with its motion regularized, or true node, which takes the oscillations of nodal motion into account. |
The nodes have been treated differently across periods and astrological traditions. The correspondences presented here belong to historical Western astrology. They should not be confused with the Indian doctrines of Rāhu and Ketu, which have their own texts, rules, and methods.
Guidance for interpreting the South Node
Always read the entire axis. The South Node and North Node are inseparable. A reduction in one house is accompanied by an increase in the opposite house.
Give priority to the sign ruler. The node rules no sign in traditional Western doctrine. The ruler indicates what directs the outcome, where it leads, and whether it can be contained.
Do not confuse reduction with misfortune. Fewer debts, conflicts, obligations, or distractions can be beneficial. The nature of the house and the condition of its ruler determine the value of the outcome.
Tighten the conjunctions. A planet close to the Dragon’s Tail deserves careful consideration. A wide contact or simply sharing a sign does not justify the same conclusions.
Respect differences among authors. Bonatti and Lilly do not describe the South Node’s action near challenging planets in the same way. Judgment should be based on dignity, sect, rulership, and the figure as a whole.
Set moral injunctions aside. The South Node does not command anyone to abandon part of themselves. It shows a dynamic of withdrawal or diminution to be integrated into the overall judgment of the chart.
To keep in mind
A point of diminution, not a spiritual debt
The South Node alone cannot establish past lives, karma, an innate talent, a fault to be repaired, or an inevitable event. A serious interpretation takes into account the sign, house, traditional ruler, North Node, and planets that are actually nearby. Astrology describes a symbolic configuration; it does not remove freedom of judgment or responsibility for one’s decisions.
