4 articles for "Vertex"

Astrologically, the point defined by the western intersection of the prime vertical and the ecliptic, opposite the anti-vertex in the east. Generally, it is the point on a limb of an object farthest from an observer's horizon. The Moon's vertex is used in observations of lunar occultations. The longitude of the Vertex may be computed with the formula:

ARCCOT (-((COT f x SIN e) - (SIN RAMC x COS e))/COS RAMC)

where e is the obliquity of the ecliptic and f is the angle between the zenith and the RAMC. For the mid latitudes, the position of the vertex with an astrological chart is predictable, occurring one or two houses either side of the Descendant angle. Time of day, time of year, and exact latitude are variables in the position of the Vertex. For subtropical latitudes the position of the Vertex is very erratic, just as the position of the Ascendant is in extreme northern or extreme southern latitudes. For a birth at 0 latitude, the Vertex and the Descendant would be one and the same, as would the Antivertex and the Ascendant. In other words, the Vertex and Equatorial Ascendant axes are one and the same for births at 0 latitude. Jayne observes that the Vertex is the descendant of the horizonal house system. Today, the vertex is generally thought of as a sensitive "relationship point"; an astrologer would look for contacts between the vertex and transits or progressions, or planets in another's chart. For example, one person's vertex in conjunction with another's person's Venus: this establishes a love connection. The vertex has even been noted in horary charts, allying the querent with the quesited person (the ascendant in a horary chart is frequently used in this way). Jayne and Johndro are credited with simultaneously and independently giving the vertex interpretive prominence in astrology. Johndro called the Vertex the "electric ascendant" and Jayne thought of the vertex as the whole Vertex/Antivertex axis, and wrote of its "significant end . . . on the setting side of the chart." Using traditional astrological interpretation of the eastern half of the horoscope as "personal" and the western half as "impersonal" (the split occurring along the Midheaven axis), Jayne called the vertex "the most fated of the three Angles" (the others being the ascendant and midheaven): The vertex is naturally of interest in assessing relocated natal charts, since as the "third angle" of the chart it is sensitive to change. For example, relocation moves Venus from the fifth house to the sixth house, and moves the vertex to a partile conjunction with Venus (where there is a separation of several degrees in the natal chart); relocation, then, involves a sort of double emphasis on relationships, bringing Venus, which relates to love, together with the vertex, a sensitive point in relationships. In this sixth house, this relocated suggests a "nonseparation" of work and love with a very critical element; aspects to this formation would determine the nature and productivity of the criticism.

Today the vertex is generally thought to represent a sensitive "relationship point." An astrologer would look for contacts between the vertex and transits, progressions, or planets in another's chart.

"If the ascendant refers to one's BENT or personal inclinations, and the M.C. to one's STATUS, then the vertex may refer to one's ROLE. One's role or the `part one plays' is NOT a matter of personal choice at all but is fated or destined, being determined by one's 'part' in various social and collective situations. In this respect it is much like the actor who asks for a part in a play. He usually takes the part he or she can get. The part was not written by the actor so that an actor is very much at the mercy of the playwright or director. Planets which are strongly linked by aspect to the vertex are, therefore, very much bound up with the impersonally fated part of the life of that native."

The vertex is naturally of interest in assessing relocated natal charts, since — as the "third angle" of the chart — it is sensitive to change.

One of the seven major sensitive points in the horoscope. It is astronomically defined by the intersection of the Prime Vertical and the Ecliptic in the Westerly direction. The opposite point from the Vertex is the Anti-Vertex.

;One of several methods of directions.

This method of direction is based on the distance from the natal vertex to the progressed vertex (derived from a solar-arc directed MC). This arc is applied to all planets in the natal chart in order to arrive at their directed positions and all house cusps are either directed by the same arc or derived from the directed midheaven (see cusp type).

Since the vertex is commonly associated with invo- lutary or "fated" social encounters, planetary developments resulting from vertex-arc directions are thus likely to have special relevance to issues associated with, or arising from, such encounters.
